10-Digit Long Code (10DLC)

10-Digit Long Code (10DLC) is the sanctioned standard for Application-Person (A2P) text messaging utilizing a traditional 10-digit phone number. 10DLC is a reliable messaging channel with throughput levels suitable for SMS campaigns.

Support

The Campaign Registry (TCR) manages A2P 10DLC registration on behalf of major U.S. wireless carriers, providing visibility into the messaging source and content. Campaign Verify is an independent, nonprofit organization that serves as one of the vetting providers for TCR. Campaign Verify aims to prevent spoofing and disinformation in political messaging by acting as the verification layer for campaigns, committees, and PACs – ensuring campaigns are who they say they are.

VERIFICATION

After successful verification from Campaign Verify, entities should provide their Authorization Token to their Campaign Service Provider (CSP), the campaign’s text messaging provider. The CSP will register the political entity with TCR, import the Authorization Token, and unlock approval for the Political special use-case that grants higher messaging capacity, leading to increased voter engagement.

Support

TCR guidelines require Users to follow industry best practices. Please refer to the CTIA Messaging Principles and Best Practices Guide.
