## Description

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

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.

### Possible Causes

The toll-free phone number cannot be verified because the business or message content was found to be associated with a known Phishing campaign.

### Possible Solutions

Contact Twilio Support to provide Additional Information that explains your use case.
