Alphanumeric Sender IDs are partially supported. Alphanumeric Sender ID registration is possible towards T-Mobile (23001) and O2 (23002).

Without registration to these networks, Alphanumeric Sender IDs can be overwritten to a random Short Code or a Generic Sender to ensure delivery.

For more information on Alpha Sender ID registration kindly reach out to alpha_sender_id@telnyx.com.

Please make sure to always refer to our Acceptable Use Policy for Messaging.
