How Costco Electronics Codes on Your Statement
When you pay at Costco Electronics at their locations, your card issuer sees MCC 5732 in the transaction data. This code tells your bank that the purchase was made at a electronic sales merchant. Bonus reward rates on your card apply based on this MCC — not the merchant name itself.
If your card earns bonus points on "electronic sales" purchases, Costco Electronics transactions will qualify — even if your card terms only mention a category name and not Costco Electronics specifically. The key is that the MCC matches your card's bonus category definition.
You can verify the MCC on any Costco Electronics 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 5732 qualifies for bonus rewards.

About MCC 5732: Electronic Sales
Merchant Category Code 5732 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Electronic Sales industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 5732, all qualifying card programs that include electronic sales as a bonus category will apply the elevated earn rate.
The Home 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.
