# I cannot log in because the verification code is sent to an old phone number

If you can't log in to Payhawk because the two-factor authentication code is sent to a phone number you no longer use, you can either try to fix this yourself, or ask a Payhawk Administrator at your company to request the change on your behalf.

## Changing your number from the Mobile App

- If you have an ongoing session in the Payhawk Mobile App, you can [change your phone number](/help/updating-your-phone-number) yourself.
- If, apart from SMS, another second-factor method is enabled, you can log in to the Payhawk Mobile App by using that method and then change your phone number.

## Asking a Payhawk Administrator for help

To update the old phone number so you can log in, you can also ask a Payhawk Administrator at your company to send the request on your behalf:

1. Ask a Payhawk Administrator to send an email from their registered Payhawk email address to [support@payhawk.com](mailto:support@payhawk.com).
2. In the email, the Payhawk Administrator must include your name, your old phone number, and your new phone number, with the full country code, for example, +44 for the UK.

Once Payhawk updates the phone number, the verification code is sent to your new phone number so you can log in.

> [!TIP]
> Once you log in again, you can update your phone number yourself from the Payhawk Mobile App, so the number stays updated for future logins.

You also need a verified phone number to [register a trusted device](/help/adding-and-managing-trusted-devices-for-your-personal-payhawk-account). Payhawk will ask you to verify your number before you can set up a trusted device for push authentication. Once Payhawk updates the number and you verify it, you can add your trusted device.
