Online casino gaming is legal in only a handful of states, and the card networks add their own rules on top.
Seven states, licensed one at a time
Online casinos are live in New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. Maine legalized online casinos in 2026, but they aren't live yet.
Code and register every deposit
State-licensed online casinos use MCC 7801 with Visa's online gambling indicator after registration. Mastercard requires its own registration before you process.
Pay winnings as credits
Visa requires winnings paid to a card to go out as an Original Credit Transaction, never as a refund of the deposit.
Watch the sweepstakes bans
California, New York, Connecticut and Maine have banned sweepstakes casinos, and some of those laws reach payment processors too.
