10DLC SMS Registration Overview

In 2021, major US mobile carriers implemented significant changes to the requirements that allow 10DLC (10-digit long codes) / local SMS to send traffic to their networks.

In an attempt to limit spam and phishing attempts through SMS/MMS, carriers such as T-Mobile, Verizon, and AT&T have partnered with The Campaign Registry (also commonly referred to as TCR).  If registering directly with TRC provide GTE Campaign ID as provided by TCR, along with the desired display name for your campaign.

TCR is responsible for gathering information from the end users that generate B2C (business to consumer) communications from local DIDs. The goal of gathering such information is to provide a sanctioned environment for B2C communication and ensure that users are following best practices as defined by the CTIA.

As of 3/31/23, Service Providers are required to have all outbound-SMS enabled numbers registered with The Campaign Registry or through Global Telecom Exchange to remain compliant with the newest US mobile carrier 10DLC policies.

Providers that do not register their traffic ahead of the deadline may experience rejected outbound SMS traffic.

It is highly recommended to add the the TCPA language to your website that allows for customers to OPT in and Opt out from receiving SMS.  To successfully register the 10DCL process may crawl your website to verify the TCPA form exists.  


Frequently Asked Questions
