AWS End User Messaging expanded its capabilities by supporting Rich Communication Services (RCS) for Business, allowing messages to appear with verified business identities including names and logos, increasing customer trust compared to generic SMS numbers. The integration supports common notifications like one-time passcodes as well as richer conversational experiences via verified RCS agents manageable through AWS consoles and APIs.

The service includes automatic SMS fallback for devices lacking RCS support and integrates with AWS tools such as Amazon EventBridge and Amazon Lambda, enabling bidirectional, AI-powered conversational applications. This feature was made available in all AWS Regions supporting End User Messaging by March 2026, with guidance provided through AWS documentation for implementation.
