# 63002: Channel could not find the From address

Log Level: ERROR

## Description

Twilio returns this error when the `From` address in a Programmable Messaging request does not map to a configured Channel endpoint address. This error applies to WhatsApp and other non-SMS messaging channels. For WhatsApp sandbox traffic, use the `whatsapp:<sandbox phone number>` format, and for live senders use the sender address assigned to that channel.

### Possible causes

* The `From` address in the request is incorrect or does not match the channel address exactly.
* The sender address is not associated with the Channel or WhatsApp installation you are using.
* You are sending from a WhatsApp sandbox or live sender without using the channel-specific `From` format Twilio expects.

### Possible solutions

* Use the exact Channel endpoint address shown on the Channel page, and make sure the `From` value matches that address for the channel you are sending through.
* If you are sending via WhatsApp sandbox, set `From` to `whatsapp:<sandbox phone number>` and activate the sandbox before sending messages.
* If you are sending via a live WhatsApp sender, use the `whatsapp:` sender address that is configured for your number.
* Check Error Logs and Programmable Messaging Logs to review the request details, sender configuration, and the associated Message SID.
