  30511: Toll Free verification rejection - Verbal consent script must be
  provided
level: ERROR
product: Programmable Messaging
---

## 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.

### Possible Causes

Your submission indicates verbal consent is used, but:

- No verbal consent script was provided
- The script or documentation for verbal opt-in was incomplete
- The verbal consent process could not be verified

### Possible Solutions

- Submit a detailed script showing the exact language used for obtaining verbal consent
- Include a simulated conversation demonstrating how users are informed and how their consent is collected
- Provide documentation of how verbal consent is recorded and stored
- Include instructions for how users can opt-out after providing verbal consent
- Consider implementing a confirmation text message after verbal opt-in
