Legislation was passed in 2023 requiring all businesses using SMS to communicate with customers to register their phone lines for A2P 10DLC in an effort to reduce the number of spam messages that people were receiving. Regardless of your SMS provider, you’ll need to complete the A2P 10DLC registration.
What is A2P 10DLC?
According to Twilio, “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. Carriers in the US consider all Twilio traffic to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality and lower filtering risk than long code SMS of the past, using the same phone numbers” (Twilio: What is A2P 10DLC).
- Toll Free Number Verification: if you send more than 2k messages per day or regularly work with Canadian numbers this should be done.
