About MCC 5251: Hardware Stores
Merchant Category Code 5251 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Hardware Stores industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 5251, all qualifying card programs that include hardware stores as a bonus category will apply the elevated earn rate.
The Retail 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.
