# 63007: Twilio could not find a Channel with the specified 'From' address

Log Type: APPLICATION

Log Level: ERROR

## Description

### Possible causes

* Sending a message using a `From` address that is not associated with any Channel or WhatsApp installation.
* Sending a message using a `From` address for a Channel that is pending approval.
* Using incorrect Account Credentials for the account that owns the Sender

### Possible solutions

* See [here](/docs/messaging#channel-addresses) for supported formats of Channel endpoint addresses.
* To send messages using WhatsApp, the `From` address should be `whatsapp:<sandbox phone number>` or `whatsapp:<your twilio number>` . This can be found on the [WhatsApp sandbox page](https://www.twilio.com/console/messaging/whatsapp/sandbox) or [WhatsApp numbers page](https://www.twilio.com/console/messaging/whatsapp/numbers).
* If you are using the WhatsApp sandbox, ensure that you have activated the Twilio Sandbox for WhatsApp. This can be found on the [WhatsApp sandbox page](https://www.twilio.com/console/messaging/whatsapp/sandbox).
* Check your account SID and auth token are correct and correspond to the account that owns the Sender. You can find your account credentials in the Console [here](https://console.twilio.com/).
