PROGRAMMABLE MESSAGING
ERROR

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 messaging use case requires a double opt-in process, but:

  • Only a single opt-in was provided
  • The double opt-in process was not documented
  • The confirmation step was missing or incomplete

Double opt-in is required for certain use cases including shopping cart reminders.

  • Implement a double opt-in process for your specific use case

  • Ensure the process includes:

    1. Initial opt-in (web form, keyword, etc.)
    2. Confirmation message asking user to confirm subscription
    3. User's affirmative response to complete enrollment
  • Document the complete double opt-in flow in your submission

  • Provide example messages for both steps of the double opt-in process
