Registration for customers that have switched from the Post Office

You must complete your registration in the app or online. Afterwards, you’ll be able to log into either to manage your credit card.

Useful tips before registering

Make sure you have your credit card to hand before you register.
  • Step 1

    Begin by entering your date of birth, followed by your card details, exactly as they appear on your Post Office Credit Card, including long card number and expiry date.

  • Step 2

    You’ll be asked to confirm your mobile phone number and then asked to enter a 4-digit verification code via text message.

    If your phone number is different to the one we have on file, we’ll also send you a code to your email we have on file.

  • Step 3

    Follow the security instructions and create your new password and 5 digit passcode. You will need these to log in.

    Finally, select your marketing preferences, then choose ‘continue to login’ to complete your registration.
