# 63116: WhatsApp Sender failed to be automatically registered as OTP was not received

Log Type: CARRIER

Log Level: ERROR

## Description

OTP required to automatically verify and register WhatsApp Sender was not received by Twilio despite a successful request to Meta

### Possible causes

* An internal error at Meta is preventing the OTP from being sent.
* SMS deliverability issues between Meta and Twilio are causing the code to be lost before reaching Twilio.

### Possible solutions

* Retry your request later.
* Request the OTP to be sent via a voice call and manually verify it using the [Senders API](/docs/whatsapp/api/senders#verify-a-whatsapp-sender).
* Submit a support ticket to Twilio for further investigation. Twilio can escalate the issue to Meta if necessary, as they can adjust how the OTP is sent, potentially improving deliverability.
