Most credit cards now come with different rewards tiers based on where you use them. For example, Blue Cash Preferred® Card gives you 6% cash back on US supermarket purchases. But how do you know which stores are classified as a supermarket?
What you’re looking for is something called the merchant category code (MCC), this is four digit number used by the different card processors (Visa, AmEx, Discover, MasterCard) to classify a merchants primary business. Card processors charge different rates to businesses based on their MCC and card issuers will offer different bonuses based on your spend at these locations.
Card issuers use this data to determine what bonus rate card holders should earn on their purchases. You can find out how card processors have classified a business in the following way:
Unfortunately, Visa is the only card issuer that makes this MCC data public. AmEx, Mastercard & Discover don’t have a publicly available tool and classify merchants differently to Visa, this means that even if Visa is showing a Walmart as a grocery store if you use your AmEx they might not count it as such.
