MCC 7995

Every card transaction carries a four-digit merchant category code describing the merchant's business, and 7995 is the code for gambling (in the United States, Visa gives government-owned lotteries, government-licensed online casinos and government-licensed horse and dog racing their own codes, 7800, 7801 and 7802). It is a small piece of data with large consequences. Issuing banks use it to apply policy: to decline gambling transactions outright, to treat them as cash advances on credit cards, or to offer customers a gambling block, a self-imposed control that most British banks now provide and that regulators encourage. Card schemes use it to police their networks, requiring acquirers to code gambling correctly and penalising those that miscode it to evade blocks. Regulators use it to enforce: payment-blocking measures against unlicensed operators in several countries work by targeting the code. Britain's ban on credit-card gambling from April 2020 works differently: it is a licence condition requiring operators to refuse credit card payments and to make sure e-wallet deposits were not loaded from a credit card.

For operators, the code is why card acceptance is harder than for other merchants and why decline rates are high. A deposit declined because the issuer blocks 7995 is invisible to the operator except as a failed transaction, and a significant share of gambling card deposits fail for that reason, which is one driver of the industry's shift toward bank transfers, open banking and e-wallets. Miscoding, processing gambling under a different code to avoid declines, is a scheme violation that has ended acquirer relationships and drawn regulatory action, and it is the mechanism by which some unlicensed operators have historically taken card payments.

The code is also a research tool: banks and regulators can measure gambling spend across the card system by it, which is how estimates of consumer gambling expenditure and of the effect of the credit card ban were produced.
