Using Alphanumeric Sender IDs with Twilio

You can send SMS status notifications with an Alphanumeric Sender ID, such as Status, so recipients see a recognisable sender name instead of a phone number.

How to use a Sender ID with Sorry™

Add the alphanumeric sender to the sender pool of the Twilio Messaging Service connected to your status page. Complete any registration Twilio requires for your destination countries first.

See Configuring Twilio for SMS Notifications for the connection steps.

Choosing a valid Sender ID

• Use no more than 11 characters.
• Use ASCII letters, digits and spaces.
• Include at least one letter. A sender ID cannot contain only numbers.

Check Twilio's current sender ID requirements before choosing a name.

Country-specific limitations

Alphanumeric Sender IDs are for one-way messages and are not supported in every country. Some destinations require registration. Where alphanumeric senders are not supported, Twilio uses a phone number from the Messaging Service, so your sender pool must also suit those destinations.
