# 63102: Account already linked to another WABA ID

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when your Twilio account already has WhatsApp Senders linked to a WhatsApp Business Account (WABA) and you try to register or link a sender with a different WABA ID. Use one WABA for all WhatsApp senders in the same Twilio account or subaccount.

### Possible causes

* You selected a different WABA ID than the one already linked to the Twilio account.
* You are registering an additional WhatsApp sender in the same Twilio account or subaccount and selected a different Meta Business Portfolio or WABA than the one used for the first sender.

### Possible solutions

* Use the same WABA ID that is already linked to the account when you register another WhatsApp sender.
* If you need to move this account to a different WABA, delete all existing WhatsApp senders from the account first. The WABA mapping stays connected to the account until all WhatsApp senders have been deleted.
* If you need to use a different WABA without removing existing senders, create a different Twilio subaccount and connect the new WABA there.
