Starting August 31st, 2023, major carriers such as ATT, Verizon and T-Mobile are regulating the sending of SMS and MMS messages to their subscribers in order to reduce spam and unwanted messages. They are now requiring senders to register their businesses and their phone numbers with The Campaign Registry.

If you send SMS or MMS through, you will want to register your business, a process known as 10DLC registration (10 Digit Long Code - our industry finds acronyms irresistible)

Any organization that sends SMS or MMS without registering for 10DLC will see its outbound messages being blocked or filtered.

Who is impacted?

All customers who use the Business SMS functionality of to send SMS and MMS are affected by these carrier regulations.

What happens if I don't register for 10DLC?

Any organization that does not register for 10DLC (10 Digit Long Code) will be subject to messages being heavily filtered or blocked. In short, your text messages are at high risk of not being delivered.

How does the 10DLC registration process work?

  1. You submit a business registration and SMS campaign form

  2. We send your information to our carrier

  3. Our carrier sends your information to The Campaign Registry (TCR)

  4. The Campaign Registry approves or denies your registration

  5. We get the status back and let you know if more info is needed, or if it was approved.

How can I get my business registered on the first try / quickly?

  • Carriers want to know unambiguously which business and which brand is responsible for sending the messages

  • Carriers want to ensure that you obtain an opt-in permission from the leads/customers you want to text

  • Carriers don't accept opt-in that was collected by a third party - if you buy phone lists from third parties and then text them, that is not acceptable consent.

  • Carriers are allergic to certain industries (cannabis, prescription medications, sex, hate, firearms)
