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

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.
