# 80606: Proxy Identifier Not Owned By Account

Log Level: WARNING

## Description

This warning occurs when you explicitly assign `ProxyIdentifier` or `ProxyIdentifierSid` for a Participant, but the proxy number does not belong to the account making the request. When you specify a proxy number for a Participant, Proxy attempts to use the Twilio number you provide, and that number must be owned by your account.

### Possible causes

* The `ProxyIdentifier` value points to a Twilio number that belongs to a different account or subaccount.
* The `ProxyIdentifierSid` value references a `PN` SID that is not owned by the account used for the request.
* Your application is creating or updating the Participant with credentials for the wrong account or subaccount.
* You are trying to reuse a proxy number from another project instead of selecting a number that is owned by the current account.

### Possible solutions

* Verify that you are using the correct `AccountSid` and auth credentials for the account that owns the proxy number.
* Confirm that the `ProxyIdentifier` value is a Twilio number on your account, or that the `ProxyIdentifierSid` value matches a `PN` SID on your account.
* If you need to assign a specific proxy number, use a Twilio number that is owned by the same account as the Proxy Service.
* Add the correct Twilio number to your Proxy Service before assigning it to a Participant.
* If the number is owned by a different account or subaccount, move the number to the correct account or update your request to use a number owned by the current account.
