Merchant Category Code 4112 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Passenger Railways industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 4112, all qualifying card programs that include passenger railways as a bonus category will apply the elevated earn rate.
The Transportation industry group encompasses several related MCCs. Not all merchants in a similar business will share the same MCC — for example, a grocery store inside a warehouse club may code as wholesale ({"5300"}) rather than grocery ({"5411"}). Always verify with your issuer if you're unsure whether a specific merchant qualifies for bonus rewards on your card.
