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).

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 VoIP Innovations 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.

• Effective 2/1/23 – Campaigns with at least one associated A2P 10DLC number and no active messaging traffic with T-Mobile since December 1st, 2022, may be subject to a $250 monthly recurring non-use pass-through fee per Campaign starting on February 1, 2023.  

  • T-Mobile requires that A2P 10DLC Campaigns have at least one 10DLC number associated with a Campaign which has active T-Mobile messaging traffic during a rolling 60-day period.
