# 63113: Sender Cannot Be Verified

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs during WhatsApp sender registration when the verification code cannot verify ownership of the sender. Request a new verification code and complete verification again through the Senders API.

### Possible causes

* The verification code submitted in `configuration.verification_code` is incorrect.
* Too many verification attempts were made in a short period, which can prevent the sender from being verified with the current code.
* OTP delivery was delayed or the phone number could not receive the SMS or voice verification needed to complete registration.

### Possible solutions

* Wait a few minutes, then request a new verification code by making another `POST /v2/Channels/Senders` request.
* Submit the new code with the correct `configuration.verification_method` and `configuration.verification_code` in `POST /v2/Channels/Senders/{Sid}`.
* If SMS verification does not work, try the `voice` verification method when the phone number can receive voice OTPs.
* Confirm the phone number can receive inbound OTPs. Numbers behind IVR or computer-operated systems, or numbers that only support outbound traffic, cannot complete manual OTP verification.
* Fetch the sender and confirm that `status` changes to `ONLINE` after registration completes. If it does not, review the sender error logs and follow the recommended actions.
