  30517: Toll Free verification rejection - Shopping cart reminders must follow
  specific guidelines
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 shopping cart reminder messages, but does not meet the specific requirements for this use case:

- The opt-in terms don't explicitly mention shopping cart reminders
- There is no double opt-in mechanism via text
- The privacy policy doesn't disclose how abandoned cart data is captured
- The terms and conditions don't reflect the shopping cart reminder policy

### Possible Solutions

- Update your opt-in terms to explicitly state that the program includes shopping cart reminders
- Implement a double opt-in mechanism via text that clearly informs users about cart reminders
- Revise your privacy policy to disclose how abandoned cart data is captured (cookies, plugins, etc.)
- Ensure terms and conditions reflect your shopping cart reminder policy
- Limit reminders to one alert per unique abandoned cart within 48 hours
- Confirm cart notifications do not complete transactions or collect payment via text
