Effective August 31, 2023, all 10DLC phone numbers used to send SMS messages to U.S. phone numbers must be fully registered to an approved campaign under your brand. Messages sent using unregistered phone numbers will be subject to a full block of all unregistered U.S.-bound messages sent after August 31, 2023.

What is the A2P 10DLC?

A2P 10DLC refers to a system in the United States that allows businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code (10DLC) phone numbers.

Having your brand registered and approved with the 10DLC means better delivery quality and lower filtering risk for you and your team. This process is required for any brand that is messaging candidates in the US – no matter where you're texting from.

What do I need to do?

If you do not send any messages to users in the United States using long code numbers, you do not need to do anything.

If you do send messages to the United States using long code numbers you will need to submit your Brand Registration and your Campaign Registration.

Brand Registration (see Brand Registration & the 10DLC)
- Registered business information
- Point of Contact

Step 2. Campaign Registration

Candidate opt-in / call-to-action	The call-to-action must be explicitly clear and inform end users of the campaign. If multiple opt-in methods can be used for the same, please list them all.
Message samples	Sample messages should reflect actual messages to be sent under campaign and indicate templated fields with brackets.

Please note:

All submissions are subject to a manual vetting process and can take up to 3 weeks.

Accounts are considered to be unregistered until there is an approved and verified result – this means your team will not be able to send any messages within that time frame.
