Mastercard® Automatic Billing Updater

Find updating your card information for your automatic payments inconvenient? Citadel has a solution!

How it works: Your debit or credit card will be automatically enrolled in Mastercard® Automatic Billing Updater (ABU) service. With ABU, Mastercard® will provide updates to participating merchants who maintain your debit or credit card information on file to process your preauthorized payments. Examples of these merchants include subscription service providers, utility companies, etc., with whom you have set up automatic payments. This free service will allow participating merchants to obtain your updated debit or credit card information when you receive a new debit or credit card for any reason, such as an expired card and/or lost or stolen card. Although you are automatically enrolled in ABU, you may opt-out of this service by logging into Online and Mobile Banking and selecting 'MC AutoBiller Updater' under 'Services' from the main menu.

What are card-on-file automated payments?

  • Online retailers (Amazon, etc.)
  • Movies/music/eBook download services (Netflix, Spotify, etc.)
  • Online payment services (PayPal, etc.)

Will my debit or credit card payment information be automatically updated?

No. Automatic Billing Updater is only available to participating merchants, and they can choose the frequency at which they check for updated payment information. To avoid late payments and penalties, you must check with your merchant to ensure your debit or credit card information is updated.

What if I don’t update my debit or credit card information?

Automatic payments will fail and merchants may charge you late fees. Most merchants will contact you by phone, email, or text to notify you that your payment did not go through.

For card-on-file transactions, if you try to submit an online order using your old card number, once your Mastercard® debit or credit card is deactivated, the transaction will be declined. You should have the opportunity to update your card information and re-submit your online order.

How do I know what merchants I need to update?

We recommend contacting all of the merchants that have your old card on file for recurring payments or card-on-file transactions to confirm they have your new, updated card information. If they are an  Automatic Billing Updater partner, they may already have your new card information on file.

Why is this service being offered to cardholders?

The Mastercard® Automatic Billing Updater is required by Mastercard® for all consumer and business credit and debit cards.
