# Can't change the phone number for a technician

## Problem

The problem is that the user wants to change the technician's phone number to start the setup process. A technician already has the same phone number in their deactivated account, and the system doesn't allow you to use that number for the new technician's account.

## Solution

To solve the problem, delete the phone number from the technician's inactive account profile and then add it to the active account.

### Delete the phone number and add it to the active account

To remove the phone number from the inactive account:

1. In ServiceTitan, go to the navigation bar and click **Settings**.
