Adding and verifying phone numbers in the SMS sandbox

To get started with sending SMS messages while your Amazon account is in the SMS sandbox, create an origination identity, add the destination phone numbers, and then verify them.


As with accounts that aren't in the SMS sandbox, an origination identity is required before you can send SMS messages to recipients in some countries or regions. For more information, see Supported countries and regions.

Origination IDs include sender IDs and different types of origination numbers. To view your existing origination numbers, in the navigation pane of the Amazon SNS console, choose Origination numbers. Currently, sender IDs don't appear in this list.

To add and verify destination phone numbers
  1. Sign in to the Amazon SNS console.

  2. Create an origination identity for the phone number.

  3. In the console menu, choose an Amazon Region that supports SMS messaging.

  4. In the navigation pane, choose Text messaging (SMS).

  5. On the Mobile text messaging (SMS) page, under Sandbox destination phone numbers, choose Add phone number.

  6. Under Destination details, enter the country code and phone number, specify what language to use for the verification message, and then choose Add phone number.

    Amazon SNS sends a one-time password (OTP) to the destination phone number. If the destination phone number doesn't receive the OTP within 15 minutes, choose Resend verification code. You can send the OTP to the same destination phone number up to five times every 24 hours.

  7. In the Verification code box, enter the OTP sent to the destination phone number, and then choose Verify phone number.

    The destination phone number and its verification status appear in the Sandbox destination phone numbers section. If the verification status is Pending, verification was unsuccessful. This can happen, for example, if you didn't enter the country code with the phone number. You can delete pending or verified destination phone numbers only after 24 hours or more have passed since verification or the last verification attempt.

  8. Repeat these steps in each Region where you want to use this destination phone number.
