A merchant category code (MCC) is a four-digit number used for retail financial services to classify a business by the types of goods or services it provides.
MCCs are assigned either by merchant type (e.g., one for hotels, one for office supply stores, etc.)
or by merchant name (e.g., 3000 for United Airlines[1]) and is assigned to a merchant by a credit card company when the business first starts accepting that card as a form of payment.
[3] An MCC reflects the primary category in which a merchant does business and may be used: There are multiple resources credit card users can consult to predict how credit card purchases with given vendors may be categorized.
