What is the Alphanumeric Sender ID?

Alphanumeric Sender ID allows you to set your company name or brand as the Sender ID when sending one-way SMS messages to international destinations.

Alphanumeric Sender IDs must be between 3 and up to 11 characters in length. Accepted characters include both upper- and lowercase ASCII letters, the digits 0 through 9, and space: A-Z, a-z, 0-9. They may not be only numbers.

Alphanumeric Sender ID can be set dynamically on the POST request to our API when sending an SMS. You just need to set a valid alphanumeric ID in the FROM field and we will use that.

Consider that you need to have your account verified to Level 2 in order to use this feature. At this time, alphanumeric is not supported by the carriers in the US or Canada.
