Alphanumeric sender ID

Alphanumeric Sender IDs are displayed as a custom alphanumeric phrase like the company’s name (CONTOSO, MyCompany) on the recipient handset. Alphanumeric sender IDs can be used for various use cases like one-time passcodes, marketing alerts, and flight status notifications.

There are two types of alphanumeric sender IDs:

• Dynamic alphanumeric sender ID: Supported in countries/regions that don't require registration for use. Dynamic alphanumeric sender IDs can be instantly provisioned.
• Preregistered alphanumeric sender ID: Supported in countries/regions that require registration for use. Preregistered alphanumeric sender IDs are typically provisioned in 4-5 weeks.

For list of supported countries/regions, see SMS overview page.
