For SaaS companies offering services through subscriptions, customer retention significantly controls the bottom line. Customers generally pay only a fraction of their lifetime value upfront. Therefore, retaining them is crucial for driving recurring revenue. According to HubSpot, increasing customer retention rates by just 5% can boost profits by 25% to 95%. 

However, retention alone isn't enough—businesses must balance acquiring new customers and keeping existing ones to sustain growth. Effective customer retention also opens up more opportunities for revenue growth through cross-sells, upsells, upgrades, and referrals. This also drives sustainable growth for many SaaS companies.

As Forbes points out, a company cannot grow without attracting new buyers. The key is finding the right customers with a high lifetime value (LTV) that justifies their customer acquisition costs (CAC) and retention costs.

Also, great products and services are the baselines—to thrive truly, SaaS sellers must develop tailored retention strategies that keep current customers subscribing. This is especially critical given the continual nature of SaaS tools and the potential for multi-year contracts with add-on upsell opportunities. 

In this article, we will explore how, with the right approach and tools balancing acquisition and retention, SaaS companies can acquire more valuable customers while preventing churn of existing higher-value ones.

Why is SaaS Customer Retention Important?

Here’s why SaaS customer retention is important:

Faster growth and increased revenue

According to a recent ChartMogul report, companies that prioritize customer retention grow 1.5 to 3 times faster than others.  If these numbers tell us one thing alone, it’s that customer retention is the centerpiece when looking to scale your business and drive revenue growth.

Indicates a strong product-market fit

Product-market fit is a nuanced concept. Despite conducting pre-launch feasibility studies, many businesses fall into a real vs perceived demand fallacy, realizing one or both of these a little too late:

• Their product is not needed
• Customers are unwilling to pay for it.

One surefire way to confirm product-market fit early and pivot, as needed, is to look at customer retention rates over time. A steady stream of return buyers shows that you’re solving a real problem and providing adequate value to customers.

Reduced CAC

Acquiring new customers is often expensive, so retaining existing ones can enhance cash flow and reduce marketing costs. The happier your customers are, the less you'll spend on acquiring new ones. 

As a SaaS company, Zendesk's success demonstrates this, as their focus on customer satisfaction lowered acquisition costs and improved loyalty.

Increased loyalty

Satisfied customers who consistently choose your product and have positive experiences tend to become more loyal. This fosters trust, making them less likely to switch to competitors, even if offered similar features or lower prices.

Repeat customers are more likely to recommend 

Satisfied customers who regularly use your product are more likely to become loyal brand advocates and refer others. This translates to a lower CAC and higher customer lifetime value (CLTV) for your SaaS business. 

By prioritizing a consistently positive customer experience, you're not just building a loyal following; you're creating a sustainable growth engine.

How Do You Measure Customer Retention?

Your customer retention rate (CRR) shows how you retained customers over a specific period. 

Calculate customer retention by first subtracting the number of new customers you acquired within a period from the total number of customers you have at the end of the period. Next, divide that figure by your number of customers at the start of the period and multiply your answer by 100.

Here’s the simple formula for calculating your SaaS retention rate over a specific period:

Customer retention rate (CRR) = [(No of customers at the end of the period - No of new customers acquired during the period))/No of customers at the start of the period] x 100

SaaS Customer Retention Metrics and Benchmarks

SaaS customer retention metrics are KPIs that measure how effectively a company retains customers over time, providing insights into customer loyalty, satisfaction, and overall business health.

Here are some key B2C and B2B SaaS retention benchmarks to note as you grow your business:

• Customer Retention Rate: Some experts say best-in-class SaaS businesses have customer retention rates between 85% and 87%. Meanwhile, UserPilot asserts that a good SaaS retention rate to aim for is 90%. Either way, this number can fluctuate over time due to factors like product updates, economic instability, average uptime percentage, and more.
• Customer Retention Rate by ACV: According to 2023 SaaS Capital benchmarks, products with higher annual contract values (ACV) record higher net and gross retention rates (GRR). Companies with ACVs over $250,000 had a median NRR of 110% and a GRR of 95%, while those under $12,000 had a median NRR of 100% and a more variable GRR.

• ARR Per FTE Benchmark: Founder and angel investor Bartek Pucek suggests that at scale, companies should target a high revenue per employee, aiming for $200k+ in ARR per FTE. This range indicates efficient use of human resources relative to revenue generation, suggesting operational effectiveness. 

Understanding and tracking key metrics

Consider tracking these additional SaaS customer retention metrics for deeper insights:

Customer churn rate

Customer churn rate is the percentage of customers who stop using your product or service during a specific period, the opposite of customer retention rate.

Churn Rate = (No of customers lost during a period/No of customers at start of period) x 100

Customer lifetime value (LTV)

Customer lifetime value estimates the total revenue your company can expect from a single customer throughout their relationship with you, reflecting the long-term impact of your acquisition and retention efforts.

Customer LTV = Average purchase value x Average purchase frequency x Customer lifespan

Repeat purchase rate

Repeat purchase rate shows the percentage of your customers who make more than one purchase from you over a specified period. It is a key customer loyalty indicator.

Repeat purchase rate = (No of repeat customers/Total no of customers) x 100

Net promoter score (NPS)

Net promoter score (NPS) measures customer loyalty and satisfaction by asking how likely they are to recommend your product or service on a scale of 0 to 10. 

It categorizes customers into promoters, detractors, and passives, then calculates the score by subtracting the percentage of detractors from promoters.

Net Promoter Score = % Promoters - % Detractors

Where: 

• Promoters are respondents who rate your company 9 - 10
• Passives are respondents who score 7 - 8.
• Detractors are respondents who rate your company 0 - 6 

Customer satisfaction score (CSAT)

Customer satisfaction score measures customers’ satisfaction with your company by asking them to rate their experience on a predefined scale, typically from 1 to 5 or 1 to 10. This helps you assess customers' immediate sentiment about your business and identify areas for improvement.

Customer Satisfaction Score = (No of satisfied customers/No of survey responses) x 100

Where:

• Satisfied customers are respondents who rate their experience with your brand positively (usually 4 or 5 on a 5-point scale or between 8 and 10 on a 10-point scale).

Active users

Active users are the number of unique users engaging with your product or service over a specific period. They indicate product stickiness, user-friendliness, and utility. 

Calculate active users daily, weekly, or monthly to gain insights into engagement patterns and the impact of marketing campaigns, new features, or other changes.

• Daily active users (DAU) refers to the number of unique users who engage with your product or service in a single day.
• Weekly active users (WAU) refers to the number of unique users who engage with your product or service within one week.
• Monthly active users (MAU) refers to the number of unique users who engage with your product or service over the span of a month.

For deeper insights, segment users by demographics or behavior and analyze activity patterns. 

However, first, define what “active users” or “user activity” means for your business. This could include specific user actions like logging in, engaging with content, making purchases, or other key activities. Analytics tools like Google Analytics or Amplitude can then be used to monitor and optimize user activity.

SaaS Customer Retention Strategies in 2024 with Examples

SaaS retention strategies, shaped by personalization and the right CX software, can significantly boost customer satisfaction and loyalty. Different CX providers offer varying features that support customer retention, from live chat functionality to chatbots, in-depth reporting dashboards, and more. 

We will also explore how the Service module of Plivo CX, as an all-in-one omnichannel customer service platform, can help amplify the impact of your customer retention strategies. 

To help you get started, here are five proven strategies to retain SaaS customers, reduce churn, and drive growth:

1. Create personalized onboarding experiences

Personalizing onboarding experiences for customer segments is more effective than generic onboarding. It improves customer stickiness and retention by tailoring the process to their needs. 

Utilize data gathered during sign-up, purchase, or account creation to personalize the experience.

Example

Take Notion’s onboarding flow, for instance. After signing up, the app asks you how you’d like to use it to tailor your user experience accordingly.

Next, Notion asks you to share some more details about yourself so it can show you the most relevant content and features.

The app will then prompt you to name your workspace and add an icon, like using your company name or branding, so any added collaborators can easily recognize the invite.

SaaS buying software Vendr reports that Notion’s customer retention rate is 65.83% so they’re definitely doing something right. This rate indicates long-term usability and strong user satisfaction, especially in the SaaS industry where apps with 35% retention are considered elite.

2.Offer omnichannel customer support

Excellent customer support on the channel customers prefer can significantly drive customer retention. In fact, one of the top four brand loyalty drivers worldwide is top-notch customer service.

Focus on providing a true omnichannel support experience so your service agents can promptly address customer issues or requests. 

Example

With Plivo CX's Unified Agent Desktop, agents can seamlessly switch between AI-powered live chat, voice, SMS, email, and WhatsApp. As for customers, here’s how they benefit: 

1. Faster resolution times: They experience quicker responses and resolutions to their inquiries. Since agents have immediate access to all necessary information and tools in one interface, they can address customer needs more efficiently.
   
   
2. The same quality of service on any channel: Customers enjoy a seamless experience as they move across different communication modes without having to repeat their issues or re-provide information.
3. Personalized interactions: As agents can tailor their interactions based on past engagements and known preferences, customers feel more valued and understood. This promotes their overall satisfaction and loyalty to the brand.
4. Reduced errors and miscommunications: The aggregation of communication channels and customer data in one place eliminates scopes of miscommunications and errors in handling high volume customer requests. This leads to more accurate support and a better customer experience.

3. Monitor product usage

Track product usage to identify engagement patterns and potential churn risks. At-risk customers often show signs like decreased usage or unresolved support tickets. 

Also, analyzing customer data by user segments helps you promptly identify and address churn potential.

Example

Before adopting Hotjar, the social media planning and approval brand HeyOrca needed a clearer way to measure user engagement and satisfaction. 

With the website and app analytics tools, HeyOrca has been able to assess its user experience, monitor how users interact with their app, and adjust site elements as needed.

4. Use customer journey maps

Customer journey maps help you understand the different stages users interact with your product and identify pain points or opportunities to enhance their experiences.

For example, analyzing your customer journey maps may uncover delayed verification email delivery during the signup process, which frustrates new users and leads them to churn. 

With this information, you can then troubleshoot the issue and ease the account creation process, subsequently driving up retention.

5. Make self-service more accessible

Research from 2018 showed that 88% of customers expect companies to have online self-service support portals. 

Want to keep us with modern customer requirements? Leverage live chat technology, chatbots, interactive voice response (IVR), and comprehensive help centers to help customers self-serve even when agents are unavailable or otherwise occupied.

Example

Plivo CX partners with OpenAI, keeping your customer support at the forefront of innovation. The OpenAI-driven self-service chatbot helps you offer 24/7 support to your customers. You can also train the chatbot to use only your selected content, ensuring accuracy and relevance. 

Easily build custom knowledge bases to empower both bots and human agents. When issues require human intervention, easily escalate them to your agents for faster resolution. 

With a customizable IVR, you can automate your first customer touchpoint. Guide callers through self-selected options for faster routing, shorter wait times, and quicker issue resolution. You can also further personalize the experience by incorporating customer data into greetings and voice prompts.

Customer retention is often influenced by a multitude of factors, including the quality of the website experience, response times, and the level of personalization offered. 

However, maintaining customers, especially new ones, for an extended period is a challenging and unpredictable process. 

In 2023, the retention rate for banks improved the most (4.3 percentage points) among other industries globally. On the other hand, the electronics industries witnessed negligible improvement (0.4 percentage points).

In this scenario, the right customer retention software can help you maintain existing customers and even re-engage those you may have lost along the way.

Now, let’s check out the 11 best customer retention software available today.

Plivo is introducing PIN-based authentication to its robust Number Masking API. This feature is designed to expand the utility and coverage of our number masking capabilities, catering to a broader range of use cases, including scenarios where calls originate from numbers that are not part of the number-masking session.

What is PIN-based Number Masking?

PIN-based number masking builds on our existing number masking solution, which anonymizes the phone numbers of parties in a call by using an intermediate virtual number. The new feature introduces a PIN authentication layer, enabling seamless connection even when calls originate from numbers that are not part of the number-masking session. This is particularly useful for situations where users may have multiple phone numbers or when calls are made from a number not previously associated with the application.

For example, imagine a user who signed up on a ride-sharing app with their primary phone number (let's call it Number X). One day, they need to call their driver but find that their primary phone is out of battery. They decide to use a different phone (Number Y) and call from a number that is not part of the number-masking session. Thanks to PIN-based Number Masking, they can still make the call. In such scenarios Plivo will ask for a PIN, and once the caller enters it correctly, the call connects to the driver, all the while keeping both parties' actual numbers hidden.

Who Benefits from PIN-based Number Masking?

This solution is tailor-made for businesses that operate in dynamic environments where end users or service providers use multiple SIMs or phone numbers. Whether it's a delivery service connecting drivers and customers, or a healthcare provider ensuring patient confidentiality, PIN-based number masking ensures that every call is securely connected, regardless of the phone number used.

How Does It Work?

When a call is initiated from an unregistered number, the caller is prompted to enter a PIN. This PIN, either set by the user or automatically generated by Plivo, verifies the caller's identity and connects them to the intended party, all while maintaining the anonymity of both parties' phone numbers.

Getting Started with PIN-based Number Masking

The adoption of PIN-based Number Masking involves a straightforward process, ensuring businesses can easily integrate this feature into their existing systems. Here's how to get started:

• Account Setup: Ensure you have an active Plivo account. If not, sign up with your business email and acquire a voice-enabled Plivo phone number, essential for creating number masking sessions. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.
• Creating a PIN-Based Session: Use a simple cURL request to kickstart your number masking session with PIN authentication enabled. This request should include both parties' phone numbers, a flag to enable PIN authentication (is_pin_authentication_required), and the PINs for both parties. You can also specify audio prompts for PIN entry and incorrect PIN attempts. 

 Here’s a basic template:

Ensure that is_pin_authentication_required is set to true for sessions requiring PIN verification. This step is vital for authenticating calls from unknown numbers.

• Configuration and Customization: Tailor the session to your specific needs by configuring optional parameters. These include setting custom PIN prompts and actions for incorrect PIN entries, thus offering a personalized experience for your users. Further details about these attributes can be found in the session object description.
• Session and PIN Management: Upon session creation, both parties receive the same virtual number. The PIN generated by Plivo will be unique for each party. Customers also have the option to generate unique pins for the parties involved. Plivo's system seamlessly handles the authentication, connecting calls upon successful PIN verification.
• Monitoring and Feedback: Plivo's infrastructure provides callbacks for real-time updates on PIN authentication status and session interactions. This feature is invaluable for maintaining oversight and optimizing the call experience based on actual usage.

SMS has long been the workhorse of business messaging—but there’s a new show pony in town. 

Rich Communication Services, or RCS messaging, offers a powerful upgrade that goes beyond plain text to transform business-to-customer communications.

In this guide, we’ll detail how RCS is different from OTT, SMS, and MMS, the advantages RCS can offer your business, and some tips to help you leverage its full potential for your business.

What is RCS messaging?

RCS, which stands for rich communication services, is a revolutionary protocol that upgrades traditional SMS and MMS text messages with a host of advanced features. These features include images, read receipts, suggested replies, group chats, and e-commerce integrations, making RCS messaging more engaging and informative. 

Many of these features are already familiar to consumers who use chat tools like OTT services like Facebook Messenger and WhatsApp. The big difference is that RCS messaging builds these features directly into Android and iOS; it will inevitably replace SMS altogether. 

Does RCS work on Android and Apple devices? 

Most major carriers in the US offer RCS messaging on Android devices. However, Apple only recently announced that it will adopt RCS with the release of iOS 18 in the fall of 2024.

"We believe RCS Universal Profile will offer a better interoperability experience when compared to SMS or MMS. This will work alongside iMessage, which will continue to be the best and most secure messaging experience for Apple users,” said an Apple spokesperson. 

Apple has started testing RCS messaging with iOS 18 developer beta 2, suggesting a wider release is imminent. 

Where is RCS messaging used?

The use of RCS messaging is contingent on two factors: carrier support and device compatibility. Currently, RCS messages are only compatible with newer Android phones, such as the latest devices from Samsung and Google. 

Carrier support is comparatively more common. Most major carriers in North America support RCS messaging, including AT&T, Verizon, T-Mobile, and Sprint. The map below shows where RCS messaging is available and in use in more detail. 

While RCS isn't universally available yet, it's being adopted by more and more carriers and becoming increasingly common on newer devices.

How does RCS messaging compare to MMS, SMS, and OTT?

RCS, MMS, SMS, OTT — these acronyms can quickly become confusing. SMS and MMS are legacy systems from which RCS has evolved. Let’s go through the key differences between different messaging protocols to understand why RCS messaging is so promising.

SMS (Short Message Service)

SMS messages are the most basic types of text messages. These texts can be up to 160 characters and text-only, meaning you can’t send images or video over SMS. SMS messages are compatible with virtually every mobile phone on the market and do not require an internet connection.

MMS (Multimedia Messaging Service)

MMS messages are an extension of SMS designed to send multimedia content, including images, video, audio, and text. MMS allows for more text than SMS, up to 1,600 characters. These messages are compatible with most mobile phones, but there are sometimes issues with formatting between different devices and carriers. MMS messages work over cellular networks but often benefit from an internet connection to transmit media content. 

OTT (Over-the-Top Services)

OTT messages use your phone's internet data connection rather than your mobile carrier's traditional SMS/MMS network. Apps like Facebook Messenger, WhatsApp, Telegram, and WeChat are all OTT messaging services. OTT messaging apps tend to offer more features than SMS, such as sending photos and videos, voice and video calls, group chats, and read receipts. These apps aren’t native to iOS or Android devices and must be downloaded by the user before OTT services can be accessed. 

RCS (Rich Communication Services)

RCS messages are an upgrade to MMS. These texts support text, high-resolution images, videos, audio messages, file transfers, location sharing, and more interactive elements like group chats and read receipts. However, RCS requires both the sender and recipient to have RCS-enabled devices and carriers that support RCS. 

RCS messaging offers the best set of features and security compared to legacy text messaging protocols. The only drawback is the lack of market penetration — something we expect will change with Apple’s new iOS launch. 

The future of RCS messaging for your business

The potential of RCS messaging hasn’t been fully realized, but early analysis has forecasters excited about what RCS texting can do for businesses of all sizes. “New feature-rich messaging apps, such as those built on the RCS platform, offer businesses powerful new opportunities for successfully interacting with consumers,” wrote the experts at Harvard Business Review. 

Brands such as Citi, UnoTV, Overstock, and Subway are early adopters of RCS. These companies provide case studies of how other businesses can make the most of RCS messaging. For example, Overstock uses RCS texting to send purchase, shipping, and delivery confirmations. Subway used RCS messages to send promotions with high-quality images; the campaign saw a 144% increase in its coupon redemption rate compared to the same promotion sent via SMS.

The analysts at Juniper forecast significant growth in RCS usage, expecting the user base to surpass 2 billion by 2028 — a prediction that seems well within reach given Apple’s planned release to its customers. Here’s what the mobile market could look like over the next few years. 

Given that RCS is poised to make MMS and SMS campaigns obsolete, let’s dive into why RCS can make such a big difference for your business. 

The advantages of RCS chat for your company and customers

The adoption and popularity of OTT apps signal how RCS will work for your company. Let’s break down in more detail how RCS messaging can strengthen your customer relationships. 

Deliver a better customer experience

Like WhatsApp and other OTT messages, RCS is packed with features that improve the user experience. Here are a few media capabilities built into RCS chat that can upgrade the customer experience. 

• Quality images, video messages, and GIFs
• Delivery and read receipts
• Video-calling capabilities
• Suggested replies
• Suggested actions
• Location sharing
• In-message payment options
• Sender verification
• QR codes

“With RCS, which has the richness of OTTs but is universal, consumers will get graphically branded messages from a verified sender, which may include suggested action buttons quick button replies, along with high-definition images and video,” wrote Harvard Business Review. “Survey respondents emphasize the importance of these messaging capabilities, with 81% saying that the ability to offer verified sender information is highly important.” 

Boost trust with sender verification

Brands that use RCS texting can be verified by a Verification Authority—a specialized entity, Mobile Network Operator, Chatbot Platform provider, etc. Once verified, your brand’s logo will appear at the top of the conversation along with your brand name and status badge (such as a checkmark).  

Verified sender information is among the most promising features of RCS messaging. By becoming a verified sender, your brand avoids being marked as spam and can build customer trust. Today, 70% of consumers have worried brand texts pose a data security risk; sender verification helps mitigate that anxiety.

Build strong customer communication

The many features available in RCS messaging enable brands to boost engagement and create a meaningful channel for two-way communication with customers. Interactive messaging lets customers take action directly, reducing admin for your brand while making it as easy as checking a text for customers to engage.

Imagine sending messages enriched with buttons that trigger specific actions. Customers can click a button to view product details, book an appointment, or initiate any relevant action – all within the same message thread. This ability saves customers time and frustration by eliminating the need to navigate through separate platforms.

Learn more from your data 

RCS messages generate better data and analytics from which your brand can learn. UnoTV’s RCS pilot gave the brand useful information that can trigger smarter, more targeted future campaigns. 

“With SMS, we don’t even know if the message was delivered to the user, but with RCS

we can see if it was delivered, if it was opened, and if it was interacted with,” said Violeta Rosales, UnoTV digital development lead. “It gives us a much better understanding of interactions.”

Leverage a more targeted UX 

RCS's rich multimedia experience lets your brand leverage chat history, analytics, and other customer data to build rich customer profiles. These detailed profiles become the key to crafting highly targeted messages – whether for automated responses or marketing campaigns. Tailoring compelling content that resonates with individual customers becomes much easier with this protocol. 

Use RCS messaging to grow your business

RCS messaging can supercharge your sales, marketing, and customer service. Here are a few ways to make the most of RCS’s advanced features to grow your business. 

Send captivating promos and specials

RCS messages allow brands to create eye-catching promos with image carousels, media cards, and GIFs. Many brands are already using WhatsApp to do this. Showcase multiple products at once with a call-to-action that takes the viewer straight to the shopping page, streamlining checkout. 

Early data suggests that media-rich promos significantly outperform traditional mobile campaigns. BodemerAuto, a car dealer, launched a Black Friday campaign using RCS to increase customer engagement. The campaign delivered a 17-fold clickthrough rate (CTR) improvement compared to a concurrent, text-only SMS campaign.

Manage appointments and reservations

Healthcare and hospitality companies can use RCS texting to manage appointments, send reminders, and sell event tickets. Live support, suggested actions, and AI chatbots can all be used in RCS texting to help customers manage their relationships with your business without tangling up customer service channels. 

How does this work? A salon could prompt a customer to set up an appointment with a “schedule now” button. The client would schedule their appointment directly through the text conversation. Suggested actions could also include a “reschedule” autoresponse. 

Automate account alerts 

Citi has traditionally used SMS to ask customers to verify account information, receive alerts on their spending, and get notified immediately of suspicious transactions. With RCS messaging, Citi can do more. 

“This RCS functionality allows customers to message Citi through the standard Android Messages app on their device and to access information such as their current balance and payment due date,” Wooters notes. “Our customers can also escalate their inquiry to a live agent, to address additional servicing needs.” 

Not only can Citi customers get real-time account alerts, but they can also take action directly in the message. 

Beat the competition with a great RCS strategy: 3 tips

Now is the time to start developing an RCS strategy. As this messaging protocol grows, brands that are prepared will have a competitive advantage over those that continue to rely on SMS or MMS. 

Treat your RCS text campaigns like e-mail. 

The features of RCS messaging allow you to be more sophisticated in your mobile marketing strategy. RCS messages can deliver powerful, specific CTAs, so customer segmentation is imperative. Set campaign goals, segment your contact list, and measure results the same way you would an email campaign. 

Please note that we do not suggest writing RCS messages that are as long or detailed as your e-mail campaigns. RCS messages should be used to augment your other communications channels in a more targeted, impactful way.

Start developing content on OTT apps.

More brands are signing on to use this messaging protocol every day. But, in the meantime, develop an OTT strategy that can help hone in on what content works and doesn’t. Plivo’s WhatsApp Business API allows users to effortlessly deploy WhatsApp for customer engagement while keeping costs low. 

WhatsApp for Business allows brands to send images, videos, and documents, making the messaging experience richer and more engaging. Plivo makes it easy to use the WhatsApp Business Platform to showcase a new product through a video, share a brochure as a PDF, or simply update customers on their latest transactions.

Like any tool, it’s best utilized with customer data from across your company — sales, customer service, marketing, and operations. Integrate RCS messaging with your other systems and channels to get the best results.  

Conclusion

RCS messaging is poised for explosive growth. Preparing your business for this messaging protocol now is a smart way to build customer loyalty and trust in the future. Learn more about RCS and how Plivo can help your business engage customers by getting in touch with sales.

The high risk of a security breach makes protective measures, such as two-factor authentication (2FA) and two-step verification (2SV), non-negotiable for businesses. 

An all-in-one solution like Plivo’s Verify API enables you to use 2FA and 2SV to confirm a user’s identity, yet these options operate in distinct ways that can impact your customer experience.

In this guide, we will share in-depth information about two-step verification vs two-factor authentication: their processes, semantic differences, security advantages, and how to determine which option is right for your company. 

What is two-factor authentication (2FA)?

Consumers often use two-factor authentication (2FA) in their day-to-day transactions, such as online banking, digital payments, accessing apps on their mobile devices, and others. 

Two-factor authentication uses two separate factors from different categories to authenticate a user and complete the login process. These categories could be something you know (like a password), something you have (like a smartphone or hardware token), or something you are (like a fingerprint or facial recognition). 

For instance, 2FA could require the user to know a password as well as a code from an authentication app, a fingerprint, or facial recognition. Typically, the user will type in their username and password on a device,  and then the website sends a separate one-time code (OTP) via text, voice call, or mobile app to enter the login page. Or, the user inputs their password and then uses a fingerprint or facial recognition on a separate device, like a phone or tablet, for authentication. 

This combination of using different factors from separate categories makes it significantly harder for a hacker to breach an account, even if they have the user’s password. They will still lack access to the second method (another device or biometric data). 

Examples of two-factor authentication

Here are some real-world examples of 2FA.

• Password and facial recognition on a laptop: After entering the credentials, users must complete the login by scanning their face using their laptop's built-in camera.
• Password and security token: A user inputs their password and then enters a code generated by a physical security token, such as a YubiKey.
• Password and push notification approval: A user enters their credentials on the desktop and then approves a push notification sent to their mobile device to confirm their login.

Benefits of two-factor authentication

• Provides better security: This multi-layered approach is especially effective in thwarting cyber attacks by requiring multiple forms of identification.
• Provides enhanced protection against phishing: Phishing attempts rely on social engineering to trick individuals into revealing passwords. However, biometric info or physical tokens can't easily be compromised through these methods. Even if a password is stolen, the second factor, such as a fingerprint or a security token, remains secure. 
• Designed to enhance customer trust: 2FA boosts user confidence and trust in account security. This leads to higher user satisfaction, engagement, and loyalty as customers feel more secure in their online interactions. 

Challenges of two-factor authentication

• Costs can easily escalate: Implementing 2FA can be costly and complex, requiring significant investment in new technologies, training, and ongoing maintenance and support. These costs can be a barrier for smaller businesses or those with limited budgets.
• Adoption by consumers may take time: Additional steps to log in can be seen as inconvenient, leading to potential resistance from users who prefer simpler, single-step logins. 
• Managing two devices adds complications: Losing the device used for 2FA can lock users out of their accounts, making it complex and time-consuming to recover access. Likewise, the need for two devices can be inconvenient or inaccessible for some customers. 

What is two-step verification (2SV)?

2SV also involves two verification stages, but unlike 2FA, which relies on two different methods, two-step verification relies on two knowledge factors. 

Compared to a simple one-step login process, 2SV is considered more secure. A user needs to know two separate pieces of information to access their account. However, 2SV is considered less secure compared to 2FA. 

How does 2SV work?

2SV generally involves the following steps:

1. The user enters their password to initiate the login process.
2. The user provides a one-time code sent to a registered device or answers a preset security question. The code is often sent via SMS, email, or generated by an authenticator app.

By requiring these two steps, 2SV ensures that even if an attacker obtains the user's password, they would still need access to the second verification method to gain entry.

Examples of two-step verification 

Here are some examples of 2SV in action:

• A one-time PIN in email or text: After entering their username and password, the user receives a single-use PIN or link to enter to access an account. Unlike push notifications, texts and emails are protected by their own passwords, making this method part of the same authentication category (knowledge factor) as the initial password.
• Security questions: Users are required to answer one or more security questions before they can complete the login process. This additional step ensures that only individuals who know the correct answers can gain access.
• Recovery codes: These are unique, system-generated codes provided when a password is forgotten, allowing users to regain access to their accounts. Often referred to as temporary passwords, recovery codes serve as a backup method for account recovery.

Benefits of two-step verification 

• Provides enhanced security: 2SV adds an extra layer of protection beyond just a password. This dual-step process makes accessing an account more challenging for unauthorized users.
• Easy to implement: Implementing 2SV is generally straightforward and can often be integrated with existing systems without major modifications. This makes it an accessible option for many organizations, regardless of size and budget.
• Better accessibility and experience for users: Users don’t need to switch between different devices or methods while logging in. They can access their accounts from anywhere with just a single device.

Challenges of two-step verification 

• More susceptible to phishing: While 2SV is more secure than using a password alone, it can still be vulnerable to phishing attacks, especially if the second verification step involves SMS verification or email codes. 
• Security questions weakness: Using security questions as a second factor can be weak, as answers can be guessed or found through social engineering. For instance, many people use security questions like their mother’s maiden name, which hackers can easily discover on social media. 
• Recovery process complexity: If users lose access to their registered device, they may be unable to complete the second verification step, which locks them out of their accounts. Recovery processes can be complicated and time-consuming, adding inconvenience.

What’s the difference: two-step verification vs two-factor authentication

Here’s a simple chart to illustrate the difference between two-factor authentication vs two two-step authentication. 

Picture the safety features of a car. All airbags are safety features, but not all safety features are airbags. 

Similarly, every two-factor authentication is a form of two-step verification, but not all two-step verification methods qualify as two-factor authentication.

The key difference between two-step verification vs. two-factor authentication? 2FA requires two factors from separate categories. On the other hand, 2SV has two knowledge factors, such as a password followed by a code sent via SMS text message or email​. 

For example, logging into your bank account using 2FA might involve entering your password (something you know) and then scanning your fingerprint (something you are). This approach uses two distinct types of factors, significantly enhancing security. 

In contrast, 2SV for logging into an email account might involve entering your password (something you know) and then entering a code sent to your email or phone (also something you know). 

Why 2FA is considered better than 2SV

2FA is inherently more secure and trusted in industries such as banking, government, and healthcare due to its use of varied authentication factors. 

Other security tips for verifying access

To enhance the security of your accounts and systems, consider implementing the following additional measures.

1. Use strong, unique passwords: Use passwords that are long, complex, and unique for each account. Avoid using easily guessable information like common words, birthdays, or names.
2. Enable multi-factor authentication (MFA): Whenever possible, use MFA, which combines several types of authentication factors, such as something you know (password), something you have (hardware token), and something you are (biometric data).
3. Use authenticator apps: Authenticator apps are less susceptible to interception and SIM-swapping attacks. Authenticator apps generate time-based one-time passwords (TOTPs) that can only be accessed on the registered device​.
4. Secure your devices: Lock your devices using passwords, PINs, or biometrics. Also, regularly update your devices to the latest software versions to protect against vulnerabilities​.
5. Monitor account activity: Regularly check your account activity for unauthorized access attempts. Many services will notify you of suspicious login attempts so you can quickly respond to potential threats​.
6. Educate yourself and your users: Stay informed about the latest security threats and best practices for online security. Awareness and education are key to defending against the evolving threat landscape.

By combining these security measures with 2SV or 2FA, you can significantly enhance the protection of your accounts and sensitive information, making it much harder for unauthorized users to gain access.

Governments worldwide have started mandating 10DLC registrations in response to the rise in SMS fraud. The US government has declared that all SMS/MMS messages sent to US phone numbers from unregistered 10DLC numbers will be fully blocked from September 1, 2023. Elsewhere, the consequences of not registering your number include increased carrier fees and other penalties. 

10DLC registration helps differentiate legitimate messages from spam. Here’s everything you need to know about registering your 10DLC phone number to make sure your messaging campaigns reach their intended customers and don’t get flagged as fraudulent. 

What is 10DLC registration?

10DLC registration is the process of registering your 10-digit long code (10DLC) phone number with a specific campaign (known as the messaging use case, or the reason for sending your message). Registration shows that your number and messages associated with it are approved by a mobile carrier. This approval helps verify your organization’s legitimacy and the purpose of your messages.  

Some common campaign types for 10DLC phone numbers are:

• Marketing: Promotional offers, loyalty program updates, and more
• Transactional: Order confirmations, delivery notifications, or password reset codes.
• Customer support: Real-time support through SMS chat.

Registration is especially important for application-to-person (A2P) 10DLC phone numbers. Most phones filter and sort messages based on the campaign type. For example, transactional messages and OTPs will be prioritized, whereas other marketing messages might be delivered late. 

Ultimately, registering your 10DLC phone number can build your brand’s credibility, prevent compliance issues, and ensure campaign success.

How does the 10DLC process differ for direct customers vs. resellers?

The 10DLC registration process can vary depending on your business type. A brand that directly communicates with customers can register its business entity directly.  

However, if you’re an independent software vendor (ISV) who sends SMS and MMS messages on your customer's behalf, you must register separately for each customer. 

For example, consider a hypothetical messaging platform for businesses in the United States Ovilp Corp. It should register its own brand and each of its customers' brands as individual brands. 

How does the 10DLC registration process work?

You can register your 10DLC phone number via campaign service providers (CSP) who liaise between your business and carrier. This CSP is usually the A2P provider or messaging service you use to send your messaging campaigns.

Here’s a general overview of the registration process. 

1. Submit your details  

The first step is sharing your business and campaign details with your CSP or A2P provider. This includes information like:

• Business type
• Business registration number
• Phone number
• Physical address
• Tax ID
• Website details 
• Campaign type and purpose
• Opt-in and opt-out methodology
• Sample messages

You might also have to submit extra information depending on your A2P provider. Some A2P providers offer pre-defined campaign categories to choose from, while others might ask you to create custom campaigns.

2. Register your campaign

Once you share all the relevant details with the A2P provider, they will send your 10DLC application to The Campaign Registry (TCR). TCR is a central database that stores information about registered 10DLC phone numbers and their associated campaigns and is managed collaboratively by phone carriers in the United States. 

3.  Vet your campaign

Once the A2P provider submits your campaign to TCR, mobile carriers will thoroughly vet it. This process verifies the legitimacy of your business and ensures your intended use aligns with the chosen campaign category. 

As all campaigns are manually verified by carriers, it can take anywhere from one to two weeks for your registration to be processed. 

You can track the status of your 10DLC registration through your A2P provider. You can send SMS or MMS messages immediately if your registration is approved. 

However, if your registration is rejected, you’ll have to share additional information depending on the feedback provided by the phone carrier and go through another round of vetting.

How much does it cost to register your 10DLC number?

There are three main costs associated with registering your 10DLC number, as shown in the table below. 

Here’s what each of these fees goes toward. 

Brand registration fee

This is a one-time fee to register your brand with the registry. It costs $4 for sole proprietors and low volume standard brands (those that have less than 6,000 messages per day). 

If your business sends over 6,000 messages, you must register as a standard brand, which costs $44 and includes extra vetting.  

Campaign vetting fee

This is another one-time payment, typically around $15 per campaign. It pays for the manual vetting process required to analyze each campaign's purpose and deliverability factors.

Monthly campaign fees

These are recurring fees you pay based on the type of campaign you're running, ranging from $1.50 to $10 per month. The first payment will be for three months and must be paid when your campaign is approved. After that, you’ll be charged either monthly or quarterly, depending on your A2P provider’s protocols. 

Here’s the fee breakdown for different campaign types. 

• Regular campaigns: $10 per month
• Low-volume mixed campaigns: $2 per month
• Political campaigns: $10 per month
• Charity campaigns: $3 per month
• Sole proprietor campaigns: $0.75 per month

Additional fees

In addition to the fees mentioned above, mobile carriers charge a fee for every message sent. This fee depends on the message type and your brand’s registration status. 

Unregistered brands must pay a higher surcharge, varying from $0.01 (AT&T and Verizon) to $0.006 (T-Mobile).

Standard brands might also sometimes opt to pay a Trust Score Appeal fee.  Every time a brand undergoes the vetting process, it’ll be given a Trust Score—this reflects your business’s legitimacy and potential for spam. You can apply for an appeal if you get a low trust score. 

Here are the rates:

• $10 if the score is less than 45 days old
• $40 if the score is more than 45 days old 

Also, Low-volume Standard and Standard brands pay an additional $40 when resubmitting a brand registration application. 

Note: These are the rates when publishing this blog and may vary in the future. We recommend checking with your A2P provider or mobile carrier. 

10DLC vs. Toll-free phone numbers

While most organizations prefer using a 10DLC number for A2P messaging and a toll-free number for voice calls, that’s not always the case. You can register your toll-free number via your service provider and they’ll send it to the Toll-Free Number Administration (TFNA) for approval. 

Unlike 10DLC registration, there’s no extra fee for registering your toll-free number. Plus, you can use it while your application is being processed.

However, toll-free numbers take longer to process (typically four to six weeks) and only support one-way broadcast messages. 

Depending on your preferences, you can use 10DLC or toll-free numbers for SMS/MMS messaging campaigns. Make sure you register either number type with the relevant authorities and comply with the SMS/MMS messaging regulations. 

Registering your 10DLC number with Plivo

If you’re looking for an A2P provider to manage your 10DLC phone numbers and campaigns, then Plivo can help you streamline the entire process in four simple steps.

1. Create a profile

Start by creating a profile for your brand on Plivo. Your profile will include details like your legal name, authorized contact, physical address, and business registration details. This is also where you’ll specify the type of business you run—private, public, nonprofit, government, or sole proprietor.

If you’re a reseller, you can use Plivo’s Profile API keys to set up individual profiles for each customer.

2. Register your brand 

The next step is registering your brand (or brands, in the case of resellers) with TCR. Standard brands (those who send more than 6000 messages per day) can opt for additional vetting at this point. 

Track the status of your brand registration application via the Plivo Console.

3. Register your campaigns

Once your brand is registered, you can register each of your campaigns. Here’s where you add details like campaign description, type, sample messages, and opt-in workflows for each campaign to the form shown below.

Add your campaign details to the Plivo console and initiate the campaign registration process.

In the console, you can track the status of your campaign registrations—active, processing, or failed. If a campaign is rejected, you can review the feedback provided and reapply.

4. Link campaigns to phone numbers

The final step is linking each active campaign to a phone number. Also, while there’s no limit on the number of campaigns a 10DLC phone number can be linked to, we recommend segmenting your numbers based on the campaign type—separating things like appointments, promotional offers, and customer support, for example. 

This makes it easy to keep track of numbers and helps you avoid snowshoeing—sending the same message from different numbers, which is considered a violation by most mobile carriers.

SMS marketing has an open rate of over 90%, compared to just 20%- 30% for email. However, managing a text message marketing campaign with a standard 10-digit phone number can be cumbersome. 

Fortunately, SMS short codes are a great alternative. This article explains why SMS short codes are your secret weapon for high-volume text message marketing. We'll explain what they are, why short codes are better than regular numbers, and how to leverage them to boost audience engagement.

What is a short code?

Short codes, also known as short numbers, are brief digit sequences, typically five or six digits long. They enable businesses to send and receive text messages at scale. Short codes are easy to remember and quick to type in, improving the user experience.

Let's delve into the different types of short codes and how they function.

Types of SMS short codes

There are two types of short codes used in SMS marketing and communications. 

Shared short codes

• Shared short codes are like public phone numbers. Multiple businesses can use the same short code.
• They are the most affordable option.
• However, you have no control over who else uses the code, which can confuse customers.
• You might also miss out on replies sent to the shared code by other companies.

Note: Shared short codes are phased out in countries like the USA and Canada.  

Dedicated short codes (leased short codes)

• Dedicated short codes are exclusive to your business.
• You have complete control over how the code is used.
• They ensure customers only receive your messages and the replies go directly to your system.
• Dedicated codes come at a higher cost than shared codes.

Whichever type you decide to use, all short codes can offer specific benefits to your business. 

What are the benefits of short codes for businesses?

Short codes offer several advantages over long codes or email. 

1) Improved deliverability

One of the foremost challenges in marketing is ensuring your messages reach the intended audience. Emails can be blocked by spam filters and social media ads get lost in viewers’ feeds. Short codes, however, have high delivery rates. People are accustomed to checking their text messages frequently, and short codes stand out from spammy marketing tactics.

2) Enhanced brand recall

Short codes are far easier to remember than standard ten-digit phone numbers. This memorability translates to better engagement and campaign participation. Vanity short codes take recall a step further. These spellable codes align with your brand name or campaign (e.g., "4Alerts" for a notification service). Vanity codes enhance brand recognition but may come with an additional cost.

3) High throughput and performance

Designed to handle large volumes of messages efficiently, short codes are a feasible solution for high-traffic campaigns like contests, discount alerts, or appointment reminders. They allow you to send messages to a large audience quickly and reliably, ensuring smooth communication and timely delivery.

4) Cost-effectiveness (for shared short codes)

Shared short codes offer an excellent solution for businesses looking to optimize their SMS marketing campaigns without breaking the bank. Multiple companies can share the same short code, reducing overhead costs.

Here’s a quick comparison of pricing in the United States for the different types of short codes. 

We recommend shared short codes for businesses exploring SMS marketing on limited budgets. However, a shared code means less control over branding than a dedicated code. Also, they can be used to send messages only in countries where they are provisioned. So, if your customers are not located in the US, do not get a US short code.

How do businesses use short codes?

Short codes aren't a one-size-fits-all solution. This section helps you learn how short codes are used across different industries for different purposes. 

Short codes in financial services and banking 

Banking and financial services rely on short codes to implement multi-factor authentication (MFA) for their customers. MFA adds a layer of security to protect sensitive information and prevents unauthorized account access. 

For example, the bank sends a text message with a unique code to the customer’s phone. The customer must enter the code to make the transaction or access their accounts online.

Short codes in retail/e-commerce 

Short codes can send a high volume of text messages over a short period of time. This capability makes them useful for retail and e-commerce marketing campaigns, such as sweepstakes or giveaways, as well as flash sales, discounts, and promos. Short codes can also be used in event-based promotions. 

Short codes in healthcare 

SMS short codes support two-way communication, allowing patients to respond to messages such as booking reminders. Healthcare providers and organizations can send post-visit surveys to understand patient feedback and satisfaction, regular checkup reminders, and vaccine availability. 

How do you get short codes for business text messaging?

Here’s how to secure a short code for your business with Plivo: 

1. ‍Read the guidelines: Before applying, ensure your campaign meets the guidelines for the US or Canada.‍
2. Download the application: Get the application form for your country and fill it out carefully.‍
3. Submit your application: Apply with Plivo's support team. They will review it and may ask for more information. This usually takes less than a week.‍
4. Add funds to your account: Carriers require upfront leasing fees (minimum three months). Plivo will collect these fees when you submit your application. These fees cover setup and the initial rental period, even if your application is rejected.‍
5. Plivo submits your application: Plivo will purchase the short code for you and apply it to all carriers.‍
6. Go through the carrier review process: Each carrier will comprehensively review your application and may seek clarification. Plivo will collaborate with you to address any queries, but approval is not guaranteed. This thorough process can take 6-8 weeks.‍
7. Short code goes live after testing: Once approved, the short code will be integrated into the carrier's network and tested. Then, Plivo will configure the short code for your account and make it ready to use.

Important note: Plivo cannot control carrier regulations or interpret laws. We recommend you consult a lawyer to ensure your campaign complies with all applicable laws.

Porting an existing short code

You can also switch your existing short code from another provider to Plivo. Before starting this process, make sure that you meet the following requirements. 

US port-in: Provide Plivo with three months of payment receipts from your current provider. You may also need authorization from the Common Short Code Administrator.

Canada port-in: Provide Plivo with a copy of your approved short code application from your current provider or a copy from the Canadian Telecommunications Association. You may also need a migration letter on your company letterhead.

Plivo will submit the porting application to the carriers. For a short grace period, traffic will flow through Plivo and your previous provider to avoid downtime.

By following these steps, you can get short codes and leverage the power of SMS advertising to communicate with your customers conveniently and effectively.

In 2023, fraud remained a top challenge for banks, fintechs, and credit unions. Nearly 60% of these business types suffered direct fraud losses exceeding $500K in that year. Fraud rates are increasing in both consumer and business accounts, making data security a top priority for companies. 

Phone number verification is a common, and highly effective, security best practice. By verifying a user's phone number, companies can ensure that the user is who they say they are and mitigate the risk of fraud. 

In this guide, we'll explore how to implement phone number validation during new user enrollment and highlight the benefits of using Plivo's robust phone verification solution. 

What is phone verification?

Phone verification involves confirming the ownership of a phone number entered by a user. Businesses and services commonly use it to authenticate their users' identities and ensure they can access the phone number they provided during signup. 

The verification process involves sending a code to the user's phone number, which can be delivered via text message, phone call, or messaging app. This process is particularly useful for enhancing security in online banking, e-commerce, and social media platforms. 

• Online banking: Banks and other financial institutions use verification codes to increase the security of their online services. They send a code to the user's phone number when they log in from a new device or initiate a large transaction. 
• E-commerce and marketplaces: Online retailers use verification codes to confirm the phone numbers of their shoppers before processing orders to prevent fraud and ensure that delivery updates are sent to the right customer. 
• Social media platforms: Websites like Facebook and Twitter also use phone verification codes to verify new accounts, prevent spam, and block fake numbers. 

Why use phone verification software?

Phone verification can be used for various purposes. For example, when a customer attempts to log in from a new device or location. Or, when sensitive changes are made to their account, phone verification acts as an immediate check to ensure the authenticity of the person requesting the transaction. 

Verifying phone numbers during new user enrollment is not new—companies have been doing it for decades. However, verification during new user onboarding has become increasingly susceptible to interception by fraudsters. They employ various tactics such as SIM swapping, phishing, and exploiting vulnerabilities in mobile networks.

1. SIM Swapping: Fraudsters can convince mobile carriers to transfer a victim's phone number to a new SIM card under their control. This allows them to intercept verification codes sent via SMS, gaining unauthorized access to the victim's accounts.
2. Phishing: Fraudsters send fake messages or emails that appear to be from legitimate companies, tricking users into revealing their verification codes or personal information.
3. Network Exploits: Some fraudsters exploit weaknesses in mobile networks to intercept SMS messages. These vulnerabilities can be found in older, less secure protocols still used by some carriers.

Given these growing threats, customers are more cautious than ever about sharing their personal information with businesses. Phone verification software is crucial for upholding the high-security standards that build customer trust. The best verification software includes robust governance, access controls, and compliance with security regulations to safeguard your business. 

Plivo’s phone verification platform software is designed to help companies get granular access over their verification methods, with features that: 

• Monitor your messaging patterns, establish thresholds for each country, and send automatic alerts if a pattern emerges that is unusual. 
• Fine-tune and override messaging throughput thresholds for each country. 
• Calculate your cost savings from preventing fraud with the built-in reporting. 
• Use pre-approved templates optimized for conversions.
• Reduce implementation by up to 90%.

Even if the phone number is verified, there are chances of fraudulent calls and illegal activities which can be prevented with reliable verification software. Plivo’s Verify API ensures just that—SMS and voice verification with robust fraud control. 

How does phone verification work?

Verifying a customer’s phone number is relatively straightforward. Companies most often partner with players like Plivo to add verification to their apps and platforms. Here’s how the typical phone number verification process works:

• Customer Enters Phone Number: The system automatically requests the phone verification service to send a one-time passcode (OTP).
• Sending OTP: The OTP can be sent via text, voice notification, or app notification.
• User Receives OTP: The customer receives the OTP and types it into the app.
• Verification: The app checks the entered OTP with the server to ensure it’s correct.
• Confirmation: If the OTP is correct, the user’s phone number is confirmed as verified.

When a customer enters their phone number, the system automatically asks the phone verification service to send a one-time passcode (OTP). This could be sent via text, voice notification, or app notification. Once the user receives the OTP and types it into the app, the app checks this code with the server to ensure it’s correct. If it’s right, the user’s phone number is confirmed as verified. 

To safeguard against fraud or unauthorized virtual phone numbers, codes can be sent only a certain number of times (to avoid spam), and all data sent back and forth is encrypted. Sometimes, a CAPTCHA ensures the user is real and not a robot. 

How does phone verification improve risk management?

Phone verification is an important tool to detect potential fraud early on. A reliable API call assesses the number and delivers critical information about it, such as:

• Availability (reachable or not) 
• Current network 
• Country of origin 
• Original network 
• Roaming country (if roaming is on)
• Roaming network name
• Roaming status
• Risk score 
• Unusual patterns
• Validity 

Unusual patterns may mean something's not right, like the current network being different from the original one, or the phone being associated with multiple accounts. While these patterns don’t always mean fraud is happening, it's a good idea to be cautious when dealing with those phone numbers or specific country codes.  

Best practices for phone number verification for new user enrollment 

When you have a new user, you’ll need to focus on three areas: 

• Phone number input: Collecting phone numbers from the user through an input field
• Phone number validation: Validating the phone number to ensure it is legitimate and follows the required format
• Phone number verification: Verifying the phone number by confirming the user has access to it

Best practices for phone number input

1. Place the country code in a distinct field

Plivo offers an easy-to-use interface that accommodates various global phone number formats. By separating the primary international phone code, Plivo enhances user-friendliness and ensures that phone numbers are correctly formatted into the standard E.164 format.‍

2. Change the phone number to E.164 format

‍E.164 is a standardized international format that guarantees unique identifiers for each number. Plivo’s Lookup API returns this virtual number format, which is also utilized across most of Plivo’s services, including the Verify API and Messaging APIs.

For instance, if a user inputs a Lithuanian phone number, such as 370860112345, Plivo instantly converts it into the international E.164 format as +37060112345, before sending it to other carriers. It’s important to note that the “8” is dropped in this format; the “'8” is only needed when calling within Lithuania.

Best practices for phone number validation

When you integrate Plivo's phone number Lookup API into your system, you gain access to comprehensive phone number intelligence that helps you programmatically determine the carrier, number type, format, and country for any phone number worldwide. 

Use the Plivo Lookup API to:

1. Confirm the phone number is valid 

Before including the customer in your contact list, validate phone numbers to ensure clean customer data and minimize delivery errors. SMS API calls to invalid or non-SMS-capable numbers result in a 400 Bad Request API response, which developers can conveniently relay upstream. Here’s an error message as an example. 

{ "api_id": "df5d4304-66af-11eb-91d8-0242ac110004", "error": "19332631167 is not a valid phone number" }

2. Check for line type, including mobile, landline, and VoIP numbers

Identify mobile and landline phone numbers correctly to select the right channel for your messaging and get the best conversion rates. SMS or push notifications have high conversion rates; plus, if you want to send rich media formats SMS messages, sending them via a mobile phone number will drive engagement. 

3. Create a list of approved country codes to permit 

Using a list of allowed countries when users sign up helps you meet compliance requirements, reduce fraud, and manage new user registrations smoothly. Plivo’s Lookup API automatically includes the country area code in its responses, making it simple to set up and maintain an allow list tailored to your business needs.

4. Reduce fraudulent transactions

Mitigate risk by comparing the location of the IP address and the country with other details of the phone number. If needed, add extra verification steps. for high-risk or invalid phone numbers, like premium or VoIP numbers, or if the carrier network is suspicious to improve the customer experience.

Best practices for phone number verification

1. Send a one-time passcode to verify user access to that number

Plivo’s Lookup API integrates directly into your application, allowing you to automate the process of sending OTPs via SMS when a user registers, logs in, or performs a security-sensitive action. For users who might not have reliable SMS services or prefer not to use text messages, Plivo offers the option to deliver OTPs through automated voice calls. 

Like SMS, the voice call process is integrated into your application via Plivo’s Voice API. When an OTP needs to be delivered, the API triggers a voice call to the user’s phone number.

2. Use adaptive routing for OTP delivery 

Plivo’s adaptive routing technology automatically selects the best possible route for delivering SMS and voice messages based on real-time conditions. Implement adaptive routing to increase the reliability of OTP deliveries, especially in regions known for fluctuating network conditions. This approach helps ensure that your OTPs reach your users promptly, regardless of their location.

3. Add a secondary 2FA layer

Plivo's two-factor authentication features go beyond messaging. The platform handles over a billion transactions each month and achieves an impressive 99.99% API uptime. Besides, Plivo offers senders a direct route to end users, with a one-hop maximum without route blending or dilution. This helps users send messages or make voice calls to every country globally, avoiding delays or paying for repeated failed messages. 

4. Enable real-time analytics and reporting

Plivo provides detailed analytics and real-time reporting on the status of every OTP sent, whether via SMS or voice. Use Plivo’s analytics dashboard to monitor and analyze OTP transactions. This enables you to identify and resolve delivery issues quickly, optimize the verification process, and enhance the overall user experience by reducing delays and failures in OTP reception.
