How do I resolve the "No origination identity available to send to destination number" error when sending SMS messages to United States destination numbers from Amazon SNS or Amazon Pinpoint?

Short description

SMS messages using Amazon Simple Notification Service (Amazon SNS) or Amazon Pinpoint fail to deliver if the sender doesn't have a supported origination number.

Resolution

Depending upon the destination country, your SMS messages have different requirements that must be met to make sure they can be delivered.

To be sure that your SMS messages are sent to the United States using Amazon SNS or Amazon Pinpoint, review this setup information:

Acquire a supported origination number

Send SMS messages to the United States numbers using a 10-digit long code (10DLC), short code, or a toll-free number to make sure that they can be delivered.

Note: The short code has a higher cost and a longer delivery time.

Make sure your origination number is for your AWS Region

AWS Regions have their own origination numbers. Each origination number is specific to its AWS Region and can't be used in a different Region. Be sure that you get one for your AWS Region.

Note: Each supported United States origination number has different sending capabilities, cost implications, and provision time. Keep these factors in mind when you choose an origination number.
