## Description

The Toll-Free phone number verification submission has been reviewed and it was rejected. Messaging traffic on this Toll-Free number is blocked until it's verified.

Verification is one component of ensuring A2P SMS is used by businesses in a legal and compliant manner. The review process looks at the business sending messaging (not the software powering it), the use case, sample content, the web presence, the opt-in/consent collected and associated website terms and privacy policies.
