10DLC Overview

10DLC is a local 10-digit phone number that requires Brand & Use Case registration and supports throughput levels suitable for A2P SMS campaigns. 10DLC is sanctioned by mobile carriers for A2P messaging and is intended to provide a reliable user experience, better deliverability, and higher messaging speed.

If you want to send A2P messages via 10DLC in the United States, you must register your Brand & Use Case. Major Mobile Operator Networks (MNOs) offered a grace period for registration, which is now over. All current and future MessageBird customers must adapt to the 10DLC requirements to use this number solution as the originator. Please be sure to register your brand and use cases or your SMS traffic will be blocked by network operators (carriers).

The Campaign Registry (TCR)

TCR works with North American mobile operators and companies that are in the messaging business to register Application-to-Person (A2P) text messaging Campaigns.

The registry supports a sanctioned A2P 10 Digit Long Code (10DLC) text messaging Campaign ecosystem and provides visibility into the messaging source and content, allowing mobile carriers to provide a more reliable and predictable messaging service for Campaign Service Providers (CSPs) and Brands.

Requirements for using 10 Digit Long Code (10DLC) numbers in the United States

Please note that these requirements for messaging via 10DLC do not relate to or affect toll-free numbers, WhatsApp services, and voice-only long-codes.

  • Before going live in the US, you must register and obtain approval for your brands and messaging programs per use case. Step-by-step guides on setting up brands and registering use cases are available.

  • US numbers can no longer be shared by different brands/customers. If you are sending messages on behalf of multiple brands, each brand will need to have its own dedicated 10DLC.

  • US carriers charge additional fees for brand and use case registrations as well as carrier fees per message. See below for more information on pricing changes.

  • Carriers will determine the actual messaging throughput after registration.
