Mastercard’s Automatic Billing Updater (ABU) is a free service participating merchants can use to retrieve cardholder account changes, like new card numbers or expiration dates, to ensure as little disruption as possible for your card-on-file transactions and automated payments.
These payments are processed using a card number you’ve stored with a merchant and websites with whom you’ve created an account and saved your card information, for example:
When you get a new card for any reason—for example, expired, lost or stolen cards—these merchants will be able to update your information so you don’t miss a payment.
Automated Billing Updater is only available to participating merchants and the merchants 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 card information is updated.
