The US business text messaging landscape is shifting due to new carrier requirements around A2P 10DLC messaging, aimed at protecting consumers and promoting engaging experiences. The changes require businesses sending or receiving SMS over local long codes to register with carriers, introducing transparency and trust around messages sent across networks. Dedicated routes for A2P traffic will improve reliability and throughput, while eliminating spam and unwanted messages. Registration requirements for 10DLC numbers will share information about businesses, determining their trust score and message fees. Twilio is partnering with businesses to navigate these changes, enabling registration through its Trust Hub console, streamlining the process and providing up-to-date resources and support.
