You can update the email address of your PBS account at any time by visiting your PBS Account User Profile.
Open the above link to your user profile, log in with your current account, and then click "Update Personal Information" and enter your new email address.
If you encounter an error message that a PBS account already exists with that email address, then you will be unable to update the email address as two PBS accounts cannot exist with the same email address. Please log out and log back in with the other PBS account you have previously set up.
If you own multiple PBS accounts but would like to switch the account linked to your Passport benefit, you can reactivate your benefit with your preferred account using the Passport Reset Tool.
