Alphanumeric Sender IDs For Improved Authentication and User Verification Security

Twilio is introducing a new Alphanumeric Sender ID, AUTHMSG, to improve authentication and user verification security through SMS. This change aims to increase conversion rates by providing personalized sender names and reducing the risk of message filtering or misattribution. The new feature will be automatically delivered via Twilio APIs for both Authy and Verify services, supporting 79 countries initially. With Alphanumeric sender IDs, users can expect better end-to-end international conversion, reduced friction, and increased trust in the sender's identity. This move aims to address the complexities of international SMS delivery and carrier regulations, providing a more reliable and scalable solution for developers.
