How Costco Business Center Codes on Your Statement
When you pay at Costco Business Center at their locations, your card issuer sees MCC 5300 in the transaction data. This code tells your bank that the purchase was made at a wholesale clubs merchant. Bonus reward rates on your card apply based on this MCC — not the merchant name itself.
If your card earns bonus points on "wholesale clubs" purchases, Costco Business Center transactions will qualify — even if your card terms only mention a category name and not Costco Business Center specifically. The key is that the MCC matches your card's bonus category definition.
You can verify the MCC on any Costco Business Center transaction by checking your card's mobile app or statement. Some issuers display the merchant category alongside the transaction details. For the most accurate information, contact your card issuer's customer service and ask whether MCC 5300 qualifies for bonus rewards.

About MCC 5300: Wholesale Clubs
Merchant Category Code 5300 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Wholesale Clubs industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 5300, all qualifying card programs that include wholesale clubs 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.
