Alphanumeric Sender IDs are supported with registration. Alphanumeric Sender ID registration is required.

Non-registered Alphanumeric Sender IDs will either be rejected or overwritten. However, this is on best-effort basis.

The use of generic Alpha Sender IDs is not recommended. Alpha Senders should be directly related to the message content.

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

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