There is no public way to check the MATCH list, because it is an acquirer-facing database with no merchant portal and no lookup service. What you can do is ask the acquirer that terminated you whether it placed a listing and under which reason code, and read the pattern of your declines. Both routes work, and one of them is fast.
How to check the MATCH list when there is no public lookup
Start with the acquirer that ended your account, because it is the only party that knows for certain and the only party that could ever remove an entry. Ask two specific questions in writing: was a MATCH entry placed for this business, and if so, under which reason code. Keep it factual and unemotional. You are asking for a record, not arguing a case, and the person answering is far more likely to answer a narrow question than an angry one.
Put it in writing rather than on the phone. A written answer gives you something to hand the next underwriter, and it forces the acquirer to be precise about the code, which is the detail that determines everything downstream.
What the pattern of your declines tells you
If you have applied to several unrelated processors and every one has declined quickly, without asking for documents, that pattern is itself informative. A normal decline comes after underwriting has looked at statements, volumes and category. A MATCH-driven decline usually comes before any of that, because the screening happens at the front of the process.
The tell is speed and silence together. Applications that die in a day or two with no document request, from acquirers with nothing else in common, point at a screening hit rather than at your financials.
Asking a prospective processor directly
An acquirer running your application can see the listing. Most will not read the file out to you, because it belongs to the acquirer that placed it, but many will tell you plainly that screening flagged a listing and that this is the reason for the decline. Asking that question openly at the start of a conversation saves everybody time.
It also changes the conversation for the better. A processor who knows about a listing from the first phone call can tell you whether it is placeable and what would be needed. One who discovers it three weeks in has already spent goodwill on a file that was never going to work.
Why the reason code matters more than the listing
Two businesses can both be listed and be in completely different positions. Reason code 4 is excessive chargebacks, defined by Mastercard as chargebacks in a single calendar month exceeding 1% of Mastercard sales transactions that month and totalling 5,000 US dollars or more. That describes a lot of ordinary businesses that grew fast or sold something with a high dispute rate, and it is placeable.
Codes covering laundering, collusion or fraud conviction describe alleged criminal conduct, and they close doors that stay closed. The full code table with Mastercard’s own definitions is on our MATCH list reference page. Knowing which code applies to you is the difference between a productive search and months of blind applications.
What to do once you know
If a listing exists and the code is wrong, the route is a factual dispute with the acquirer that placed it, not with Mastercard, which publishes that it does not assess the accuracy of listings. If the listing is correct, the route is finding an acquirer that boards listed merchants, which is a different search rather than an impossible one. Both paths are set out in how MATCH list removal actually works and getting a merchant account after a MATCH listing.
Either way, do not keep firing applications at processors while you wait. Repeated declines cost you nothing on MATCH itself, but they burn weeks you could spend on a file that will actually board. If you need cards running in the meantime, holding more than one merchant account is the structural fix, and it is easier to arrange before a problem than after.
Frequently asked questions
Is there a website where I can search MATCH? No. Any site offering to search MATCH for a fee cannot do what it claims, because Mastercard provides no merchant-facing lookup.
Will an acquirer tell me which code I was listed under? The acquirer that placed the listing can and often will if asked in writing. An acquirer merely screening your application generally will not read out another acquirer’s record.
Can my old processor refuse to tell me? It can decline to discuss it, and some do. In that case the reason code usually becomes apparent from the termination notice itself, which normally describes the conduct that triggered it.
Does checking cost anything? No. Asking the terminating acquirer is free, and asking a prospective processor whether screening flagged a listing is part of a normal conversation.
