Transit CallerID Sunset: Migrate to Verified CallerID or Immutable Call Forwarding Before May 31, 2026
Twilio Sunsetting Transit CallerID Feature by May 31, 2026 Twilio is discontinuing its Transit CallerID feature, which allows customers to present a different phone number than the one they're calling from. Customers currently relying on this functionality must migrate to alternative solutions—either Verified CallerID or Immutable Call Forwarding—before the May 31, 2026 deadline. This sunset represents a significant shift in how Twilio manages caller identification and phone number presentation, likely driven by regulatory compliance requirements and industry standards around caller ID authentication and fraud prevention.
