VerifySMSSandboxPhoneNumber - Amazon Simple Notification Service


Verifies a destination phone number with a one-time password (OTP) for the calling AWS account.

When you start using Amazon SNS to send SMS messages, your AWS account is in the SMS sandbox. The SMS sandbox provides a safe environment for you to try Amazon SNS features without risking your reputation as an SMS sender. While your AWS account is in the SMS sandbox, you can use all of the features of Amazon SNS. However, you can send SMS messages only to verified destination phone numbers. For more information, including how to move out of the sandbox to send messages without restrictions, see SMS sandbox in the Amazon SNS Developer Guide.
