Use this app to quickly look up an MCC description by its code and vice versa. What is MCC and how does it affect your money? MCC (Merchant Category Code) is a four-digit number assigned to a merchant that classifies the type of services it provides. Every time you pay with a credit card, the transaction contains the MCC of the merchant, so your bank knows in which category (restaurants, barbershops, etc.) your money was spent. This is how cash back and award point programs work. You might be interested in this app if: - You have a bank card with cash back/award point program and want to get a clear insight of it to maximize the profit. - You have a credit card and would like to avoid extra commissions for operations in categories considered by your bank as cash withdrawal. - You set up payment terminals for local businesses and find it useful to always have a MCC guide at hand on your mobile device.
