A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.
Unlike a 10-digit (long code) phone number, Twilio does not handle your Short Code HELP & STOP replies, or your opt-out list. You should build this functionality into your own short code messaging application.
For information on carriers’ requirements for short code HELP and
STOP replies, please see the following resources:
