To change contact number in QBO from Canadian to Indian, it sends code to previous contact which is deactivated as I moved but I can login through code from authenticator

If you can access your QuickBooks Online(QBO) dashboard using your authenticator code, you'll be able to update your phone number right away.

Just navigate to the upper right corner of your screen and follow the steps below:

1. Click your Intuit Account button next to the Gear icon.
2. Pick Manage your Intuit Account.
3. Choose Sign in & security and then Phone.
4. Hit the Change option and update it to the new Indian number.
5. Select Save.

After saving, the system will send a verification code to the new number to confirm it. You can also refer to this article for more details about the process: Update or change your Intuit Account sign-in information.
