WhatsApp error 133006: Phone number re-verification needed

Code 133006 means the phone number you are trying to register has not completed ownership verification, or its verification has lapsed, so the platform will not register it until it is verified again. Verification is the SMS or voice code step (request_code followed by verify_code) that proves the business controls the number. Registration, which connects the number to the Cloud API, can only happen after that.

You see this when a number was added to the WABA but never verified, when a number is moved between accounts, or when a previous verification was invalidated. It can also show up in migration scenarios where the number was verified under a different product.

Nothing is wrong with your PIN or token; the sequence of setup steps is incomplete.

Verification errors are synchronous and always precede registration errors in the setup sequence, so hitting 133006 actually tells you the platform can see your number - the request is just early. The end-to-end order (add, verify, register) and the codes each step can raise are laid out in the registration troubleshooting guide; the follow-on failure once verification passes is usually 133005 if the PIN is wrong.

Encode the full sequence (add number, verify, register) in your onboarding flow with state checks between steps, and do not let automation skip ahead. Keep someone who can receive the SMS or voice call on hand for the number, especially for landlines or numbers routed through a PBX, where verification is often the slowest step.
