How Optimum Codes on Your Statement
When you pay at Optimum in the app or online, your card issuer sees MCC 4816 in the transaction data. This code tells your bank that the purchase was made at a computer network services merchant. Bonus reward rates on your card apply based on this MCC — not the merchant name itself.
If your card earns bonus points on "computer network services" purchases, Optimum transactions will qualify — even if your card terms only mention a category name and not Optimum specifically. The key is that the MCC matches your card's bonus category definition.
You can verify the MCC on any Optimum 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 4816 qualifies for bonus rewards.

About MCC 4816: Computer Network Services
Merchant Category Code 4816 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Computer Network Services industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 4816, all qualifying card programs that include computer network services as a bonus category will apply the elevated earn rate.
The Utilities 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.
