An Alphanumeric Sender ID is a combination of alphabetical and numerical characters that can be displayed as the "sender" information in SMS messages, instead of a standard numerical phone number. They must contain 3-11 characters, and include only letters, numbers and spaces, e.g.: 1800NEWTOWN.

The benefits of sending SMS campaigns from an Alphanumeric Sender ID can include: *

• Increased brand awareness, with messages coming from a consistent, recognisable name.
• Higher open rates and levels of trust, with recipients more likely to open messages from a recognisable sender than an unknown numeric number.

* Alternatively, you can set up and send from your mobile number, or you can set up both options.

Possible use cases for sending from an Alphanumeric Sender ID might be:

• Communications that reflect your company message, rather than that of an individual.
• Updates and alerts that do not require a response, as recipients cannot reply to these messages.

Your Alphanumeric Sender ID must pass a verification process before you can begin sending from it.

All SMS messages (sent via standard number, or Alphanumeric Sender ID) must contain an opt-out link, to comply with spam regulations.
