Alphanumeric Sender ID

The alphanumeric sender ID allows the sender to send messages using a custom ID constructed from a combination of alpha (a-z, A-Z) and numeric (0-9) characters. This makes the caller identifiable to the receiver and companies can set their brand name as the caller ID (e.g., “PLIVO”). This is optimal for sending SMS text messages as the receiver of the message will not be able to reply to a message sent with an alphanumeric sender ID.

You can send SMS text messages with alphanumeric sender IDs by changing the src parameters to alphanumeric characters and making an HTTP POST request to the Message API.

POST https://api.plivo.com/v1/Account/{auth_id}/Message/
Note: Alphanumeric sender ID is not allowed in some countries including US, Canada, and Brazil because of carrier regulations. Therefore, non-compliance to these local carrier regulations may prevent your messages from getting delivered.

Getting Started

  1. Sign up for a free Plivo trial account.
  2. Check out our server-side SDKs page and install the right helper based on the programming language you want to use.
  3. Buy a Plivo phone number (optional).
    Note: A phone number is required only for sending SMS to US and Canadian phone numbers. However, country-specific carrier conditions may still apply. You can buy a US or Canadian phone number through the Buy Numbers tab on your Plivo account UI.
  4. Use a web hosting service to host your web application. There are many inexpensive cloud hosting providers that you can use for just a few dollars a month. Follow the instructions of your hosting provider to host your web application.
    Note: If you are using a Plivo Trial account for this example, you can only send sms to phone numbers that have been verified with Plivo. Phone numbers can be verified at the Sandbox Numbers page.

Implementation

  1. Copy the relevant code below into a text file and save it.
  2. Replace 'Your AUTH_ID' and 'Your AUTH_TOKEN' with the AUTH ID and AUTH TOKEN found on your Plivo dashboard.
  3. Add your 'src' (source) phone number. This will show up as your Sender ID. To create an alphanumeric sender ID, simply change the 'src' parameter to the alphanumeric ID you prefer (e.g., src: PLIVO). If you’re using a phone number, be sure that all phone numbers include country code, area code, and phone number without spaces or dashes (e.g., 14153336666).
    Note: You can send SMS text messages to any country using the Message API and set any 'src' number except for US and Canadian numbers. In order to send text messages to phones in the US or Canada, you will need to purchase a US or Canadian phone number from Plivo and use it as the 'src' number. You can buy a Plivo number from the Buy Numbers tab on your Plivo account dashboard.
  4. Add your 'dst' (destination) phone numbers. These are the phone numbers you wish to send SMS text messages to. To send multiple messages in a single API request, separate your destination phone numbers with the “<” character (e.g., 14156667777<14157778888<14158889999). Be sure that all phone numbers include country code, area code, and phone number without spaces or dashes (e.g., 14153336666).
    Note: If you are using a trial account, your destination number needs to be verified with Plivo. Phone numbers can be verified at the Sandbox Numbers page.
  5. Edit the 'text' field with your SMS text message.
    Note: text messages that are longer than 160 characters are concatenated and billed separately as individual text messages.
  6. Make the 'HTTP POST' request to Plivo. If successful, Plivo will queue your SMS deliver it to your recipients at a base rate of 1 message per second.
