Sender IDs & Usage
Sender ID is the name or number that is displayed as the sender of the SMS message to the receiver of the SMS message. This can be either alphanumeric (for example, PLIVO) or numeric (for example, a mobile phone number). Sender IDs identify your business and help your customers recognize and recall your brand.
These are the different types of sender IDs your company might utilize.
Longcode Sender ID
Long code sender IDs are normal phone numbers used to send and receive SMS messages. These are ten-digit numbers that enable you to have a conversation with your customers.
Shortcode Sender ID
Shortcode sender IDs are six-digit phone numbers (for example, 123456) used to send and receive SMS messages. There are no restrictions on the number of SMS messages you can send per day, per shortcode sender ID. This allows you to communicate with your customers on a large scale.
Toll-Free Sender ID
Toll-Free phone numbers in the US can be provisioned to send and receive SMS messages. Plivo is one of the few Toll-Free phone number providers who also have the capability to provision Toll-Free numbers for SMS. Best suited for official business communication as people already perceive Toll-Free numbers as business lines. Plivo can also enable your existing Toll-Free phone numbers to handle SMS.
