If you encounter an error message while trying to connect or reconnect your WhatsApp Business number, please refer to the guide below.

#### Error Code #133006

Message: `Phone number re-verification needed`

**⚠️ What does this mean?**

This error comes directly from Meta (Facebook). It indicates that for security reasons, your phone number requires re-verification before it can continue sending or receiving messages through the API.

This often happens if there has been a change in the number's status, or if Meta's security systems require a fresh confirmation of ownership.

**✅ How to fix it**

You cannot resolve this error alone inside the Zaapi app. We need to help you re-trigger the verification process.

Please reach out to the Zaapi Team immediately so we can assist you:

1. Contact us via our in-app live chat or email support.
2. Send a screenshot of the error or mention code #133006.
3. Our team will guide you through the re-verification steps to get your number back online quickly.
