Merchant Category Code (MCC)

A four-digit code classifying businesses by the type of goods or services they provide.

What is Merchant Category Code (MCC)?

A Merchant Category Code (MCC) is a four-digit code assigned by card networks to classify merchants by business type. MCCs are used for interchange rate determination (some categories get preferential rates), rewards calculation (category bonuses on credit cards), expense categorization, and compliance (some cards restrict certain MCCs). Your MCC is assigned during underwriting and affects your processing costs.

Why It Matters

MCC affects your interchange rates. Certain categories (supermarkets, utilities, education) have preferential rates. Incorrect MCC assignment can mean paying higher rates than necessary. MCC also affects whether customers can use certain cards with your business and how their purchases are categorized for rewards.
