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 console. For detailed instructions, see Requesting a number in the Amazon Pinpoint 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.

Amazon SNS SMS messaging is available in Regions where Amazon Pinpoint is not currently supported. In these cases, open the Amazon Pinpoint console in the US East (N. Virginia) Region to register your 10DLC company and campaign, but do not request a 10DLC number. Instead, use the Amazon Service Quotas console to create a service limit increase case while requesting the 10DLC number for that Region. For information on Regions where Amazon Pinpoint is available, see Amazon Pinpoint endpoints and quotas in the Amazon General Reference.


If you're new to SMS messaging with Amazon SNS, you should also request a monthly SMS spending threshold that meets the expected demands of your SMS use case. By default, your monthly spending threshold is $1.00 (USD). For more information, see Requesting increases to your monthly SMS spending quota for Amazon SNS.
