Release a phone number in AWS End User Messaging SMS

If you don't need a phone number that you had previously requested through AWS End User Messaging SMS anymore, you can release it from your AWS End User Messaging SMS account. When you release a number, AWS stops charging you for it in your bill for the next calendar month.

Important

Releasing a phone number from your AWS End User Messaging SMS account is permanent and can't be undone. If you release a phone number, you won't be able to obtain the same number again in the future.

Deletion protection has to be disabled before you can release a phone number. For more information on deletion protection, see Using phone number deletion protection in AWS End User Messaging SMS.

To release a phone number from your AWS End User Messaging SMS account using the AWS End User Messaging SMS console, follow these steps:

Release a phone number (AWS CLI)

You can use the release-phone-number CLI to release phone numbers from your account.
