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.

Why am I getting calls from these strange numbers?

If you're getting inbound calls from a strange number that doesn't look like a real phone number, check to see if it's one of the numbers below. Sometimes, the originating carrier for a call will pass through one of the following words. Twilio converts this word to digits and uses those digits as the From parameter.

RESTRICTED 737 874-2833
BLOCKED 256-2533
UNKNOWN 865-6696
ANONYMOUS 266696687
UNAVAILABLE 86282452253
No Caller ID 464


Notice: These statuses are more common when the caller is calling from a VoIP service.
