Requesting 10DLC numbers, toll-free numbers, and P2P long codes for SMS messaging with Amazon SNS


Effective June 1, 2021, US telecom providers no longer support using person-to-person (P2P) long codes for application-to-person (A2P) communications to US destinations. Instead, you need to use another type of origination ID for these messages. For more information, see 10DLC.

To request 10DLC numbers, toll-free numbers, and P2P long codes, use the Amazon Pinpoint SMS console. For detailed instructions, see Requesting a number in the Amazon Pinpoint SMS User Guide.


US mobile carriers have recently changed their regulations, and will require that all toll-free numbers (TFNs) complete a registration process with a regulatory body before September 30, 2022. For more information about registering a toll-free number, see Registering your toll-free number.

If you purchased your toll-free number on or before September 30, 2022 its status will be in the Active state until October 1, 2022, unless you've completed your registration and it has been returned with the state set to Completed. Otherwise, it will be placed in the Pending state and you will not be able to send messages with it until you've register the number, the registration has been returned or the registration is set to the Active state.

Registration can take up to 15 business days.
