“The match list” most commonly refers to one of two things: the rank order list used in the medical residency Match, where graduating medical students are paired with training programs, or the Mastercard MATCH list, a database that flags high-risk merchants in the credit card processing industry. Both carry significant consequences, but they work in completely different ways. Here’s what you need to know about each.
The Medical Residency Match List
In medical education, “the match list” refers to the rank order list (ROL) that applicants and residency programs submit to the National Resident Matching Program (NRMP). Medical students rank the programs where they want to train, from most preferred to least preferred. Programs do the same with applicants. A computer algorithm then pairs them up, and the results are announced on Match Day.
The term also gets used more casually to describe the published results: the list of which students matched to which hospitals. Many medical schools release this publicly, and it’s a point of pride for students and institutions alike.
How the Matching Algorithm Works
The NRMP algorithm is “applicant-proposing,” meaning it starts by trying to place each applicant into their most preferred program. If that program doesn’t also rank the applicant, the algorithm moves to the applicant’s second choice, then the third, and so on down the list.
An applicant gets a tentative match with a program when two conditions are met: the program also ranked the applicant, and either the program still has open spots or the applicant is preferred over someone already tentatively matched there. If a previously matched applicant gets bumped, the algorithm goes back to that person’s rank order list and tries the next program down. This process continues until every applicant’s list has been fully considered. At that point, all tentative matches become final and binding.
The key takeaway for applicants: rank programs in your true order of preference. The algorithm is designed so that you can never be hurt by ranking a reach program first. If you don’t match there, the algorithm simply moves to the next one on your list, with no penalty.
Match Day Timeline
For the 2026 Main Residency Match, the rank order list certification deadline is March 4 at 9:00 p.m. ET. After that point, neither applicants nor programs can change their lists. Match Day is March 20, when results become available at 12:00 p.m. ET through the NRMP’s R3 system and courtesy emails. Medical schools typically hold Match Day ceremonies at the same time.
Students who don’t match to any program on their list enter the Supplemental Offer and Acceptance Program (SOAP), where unfilled positions are offered to unmatched applicants during the days between Match Week Monday and Match Day.
The Mastercard MATCH List for Merchants
In the credit card processing world, MATCH stands for Member Alert to Control High-risk Merchants. It’s a database maintained by Mastercard (though Visa runs a similar system called VMSS) that payment processors check before approving a business for a merchant account. If your business is on the MATCH list, most processors will decline to work with you, which effectively cuts off your ability to accept credit and debit card payments.
The list exists to protect banks and card networks from businesses that have a history of fraud, excessive chargebacks, or other serious violations. It’s sometimes called the Terminated Merchant File (TMF), a name that reflects its original purpose: tracking merchants whose processing accounts were shut down.
What Gets a Business on the MATCH List
A business can land on the MATCH list for either qualitative or quantitative reasons. Qualitative reasons include fraud convictions, transaction laundering (processing payments on behalf of another business to disguise the true nature of the transactions), data breaches, identity theft, illegal transactions, merchant collusion, and violations of card network standards or PCI data security requirements. Bankruptcy, liquidation, or insolvency can also trigger a listing.
The quantitative triggers are more specific. For Mastercard, excessive chargebacks means your chargebacks in any single month exceeded 1% of your sales transactions and totaled $5,000 or more. Excessive fraud means your fraud-to-sales ratio hit 8% or higher, with 10 or more fraudulent transactions totaling at least $5,000 in a calendar month. Visa’s thresholds are different: excessive fraud kicks in at $250,000 in fraud with a 1.8% fraud-to-sales ratio, while excessive disputes require 1,000 disputes and a 1.8% dispute-to-sales ratio in a single month.
The acquiring bank, meaning the financial institution that provided your merchant account, is the one that adds you to the list. Mastercard doesn’t add businesses directly.
How Long the MATCH Listing Lasts
Once a business is placed on the MATCH list, the listing stays active for five years. After that, it’s automatically removed with no application process needed. Early removal is possible but uncommon. It only happens if the listing was made in error or if the acquiring bank that placed you on the list agrees to take it off. Mastercard itself doesn’t handle removal requests.
If you believe your business was listed incorrectly, contact the processor that terminated your account. Ask which reason code they used and whether the listing matches what actually happened. If you have a case, you’ll need to submit a written request to the bank with supporting documentation: contracts, emails, financial records, or anything that demonstrates the listing was inaccurate. Be prepared for a slow process with no guarantee of success.
Practical Impact of Being on the MATCH List
For merchants, a MATCH listing is one of the most damaging things that can happen to a business that depends on card payments. Most mainstream payment processors run a MATCH check during onboarding, and a listing is usually an automatic disqualification. Some high-risk processors will still work with listed businesses, but they charge significantly higher processing fees and may impose rolling reserves, where a percentage of your sales is held back as a buffer against future chargebacks.
You won’t receive a notification when you’re added to the list, and there’s no public search tool to check your status. You’ll typically find out only when a new processor declines your application or when you ask your former processor directly. If you’re a business owner whose merchant account was recently terminated, it’s worth confirming whether you were added so you can plan accordingly and explore your remaining options for accepting payments.
