US A2P10DLC for Developers

The A2P10DLC initiative aims to increase customer trust in SMS and reduce fraud by introducing changes to the way telecommunication carriers handle Application-to-Person (A2P) messages in the US. The new rules will separate trusted senders from untrusted ones, allowing for increased throughput and better handling of application-to-person messaging. This change impacts developers using Twilio's Programmable Messaging for SMS in the US, with some changes including carrier-imposed fees, brand registration requirements, a Trust Score concept, and restrictions on certain use cases such as cannabis-related messages. The goal is to improve the security and trustworthiness of SMS, while minimizing disruptions to developers.
