It’s easy to verify a toll-free number with Twilio. After buying a toll-free number or porting in an existing toll-free number, you can choose to verify your number through the Messaging Compliance API or Console.
This requires you to create a Customer Profile with business, contact, and location information along with your messaging use case and submit it for review.
All toll-free numbers in the US and Canada need to be verified for transparency with the carriers, compliance, and optimal delivery.
