Requesting Sender IDs for SMS Messaging with Amazon Pinpoint

A sender ID is a custom name that's displayed as the message sender on the receiving device. For example, you can use your business brand to make the message source easier to recognize.

Support for sender IDs varies by country or region. For example, messages delivered to U.S. phone numbers don't display the sender ID. For the countries and regions that support sender IDs, see Supported Regions and Countries.
