How to Keep Your SMS Messages from Getting Blocked: A Step-by-Step Guide for SMS/MMS Registration Under 10DLC Through The Campaign Registry (TCR)

As of February 1, 2025, significant changes have been implemented regarding SMS registration, particularly affecting businesses that utilize SMS for communication.


Here is a breakdown of what this new ruling has affected and how to prepare your business to stay in compliance with new regulations.


Mandatory Registration for Business SMS Campaigns:

U.S. mobile carriers now require all businesses to register their SMS campaigns through The Campaign Registry (TCR). This initiative, known as 10DLC (10-Digit Long Code), aims to enhance the security and reliability of SMS communications by ensuring that all business-related messages are sent from verified sources. Unregistered SMS traffic is subject to blocking by carriers, leading to potential disruptions in message delivery. Therefore, businesses must complete their registration to maintain uninterrupted SMS services.


Registration Process and Requirements:

The registration process involves providing detailed information about the business, including the legal name, tax identification number (EIN), and a description of the intended SMS campaign. Businesses are also required to submit sample messages and outline their opt-in and opt-out procedures to ensure compliance with regulations. The registration process can take several days, and businesses are encouraged to initiate it promptly to avoid service interruptions.


Implications of Non-Compliance:

Failure to register SMS campaigns can result in messages being blocked or filtered by carriers, leading to communication breakdowns with customers. Additionally, businesses may face increased fees and potential fines for non-compliance. To prevent these issues, it is imperative for businesses to adhere to the new registration requirements and ensure all SMS communications are properly vetted and approved.

The changes effective from February 1, 2025, underscore the importance of compliance in business SMS communications. By registering through The Campaign Registry and adhering to the outlined guidelines, businesses can continue to engage with their customers effectively while maintaining trust and credibility in their messaging practices.
