The MATCH List is a list maintained by MasterCard for itself, the other brands, the other payment companies, and credit card, processors. It is a list that contains those merchants that these members believe pose a high risk for problems in the future. They may be problems related to high chargebacks, problems related to data-breach, or something else. And the list is also called, the “Member Alert To Control High-Risk Merchants”, and once a merchant is on that list it’s going to be very hard to get credit card processing into the future.
