  30513: Toll Free verification rejection - Opt-in not sufficient: Language
  Unclear
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

The opt-in language in your submission is insufficient because:

- It lacks clear language requesting consent for messaging
- SMS or text messaging isn't explicitly mentioned
- Consent language is hidden in terms of service or privacy policy
- The language doesn't clearly indicate what the user is agreeing to receive

### Possible Solutions

- Add explicit language to your opt-in form that clearly requests consent for SMS messaging
- Separate messaging consent from other agreements (privacy policy, terms of service)
- Use clear statements like "I agree to receive text messages from \[Business Name]"
- Ensure consent language is prominently displayed, not hidden or in small print
- Describe the types of messages users will receive (e.g., promotions, account alerts)
