Carrier / Twilio A2P 10DLC

What you need to know about the New Carrier / Twilio A2P 10DLC Updates

Effective July 5, 2023, all 10DLC phone numbers used to send SMS and MMS 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 gradual increase of message blocking by Twilio, beginning on July 5, 2023, ultimately leading to a full block of all unregistered U.S.-bound messages sent after August 31, 2023.

• Following other U.S. carriers raising fees for unregistered messages to encourage 10DLC registration, Verizon will increase its per-message rate on unregistered traffic, effective July 1, 2023.

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.
Special Use Cases are now supported, however if you are a customer registering a special use case requiring additional carrier approval or a 527 Political Organization, please see our guidance on Special Use Cases before proceeding with registration.

Register now to benefit from improved deliverability and increased throughput in the new verified A2P 10DLC ecosystem. A2P 10DLC comes with new registration requirements for businesses who intend to send long code messages to AT&T in the US.
