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.
