Using Alphanumeric Sender IDs with Twilio

ou can configure SMS status notifications so that they're delivered to your audience using an Alphanumeric Sender ID such as "Status" rather than a phone number.

Using a Sender ID helps your users quickly spot who the message is from and also means you don't have to buy a dedicated phone number from Twilio.

Choosing a Valid Sender ID

• It must be between 1 and 11 characters long.
• Only contain numbers and letters.
• It cannot contain spaces or special characters.

Country-Specific Limitations

Some countries don't support using Alphanumeric Sender IDs or impose limits on when and what you can send; you can find out which countries support this feature on the Twilio help centre.
