# 22132: Not Portable - Already in Twilio different owner

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio returns this error when a portability check returns `ALREADY_IN_TWILIO_DIFFERENT_OWNER`. The phone number already exists on another Twilio account, so you cannot port it into the target account as a new port-in request. Move the number to the correct account instead.

### Possible causes

* The phone number already exists on another Twilio account.
* You tried to port a number that is already in Twilio's inventory instead of transferring the existing Twilio number to the account that should own it.
* The target account for the portability check is different from the account that currently owns the number in Twilio.

### Possible solutions

* If the number needs to move between different Twilio accounts, request a phone number transfer through Twilio Support. Include the phone number, the losing and gaining Account SIDs, approval from both sides, and any required regulatory `AddressSid` or `BundleSid`.
* If you are moving the number between your main account and a subaccount, or between subaccounts under the same parent account, transfer it with an HTTP `POST` to the `IncomingPhoneNumber` resource and set `AccountSid` to the destination account.
* Reconfigure the number after the transfer completes. Number configuration does not carry over automatically, and messaging settings such as opt-outs, A2P registrations, and related WhatsApp sender setup may need to be recreated or moved separately.
