You can verify the MCC on any Curb 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 4121 qualifies for bonus rewards.
Merchant Category Code 4121 is assigned by card networks (Visa, Mastercard, Amex, Discover) to classify businesses in the Taxicabs and Limousines industry. Issuers use MCCs to determine which transactions qualify for bonus reward rates. When a merchant is assigned MCC 4121, all qualifying card programs that include taxicabs and limousines as a bonus category will apply the elevated earn rate.
The Transportation 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.
