Merchant Category Codes (MCC) MCC Codes (merchant category codes) are provided to merchant accounts during the setup process to distinguish between different types of businesses and industries. Each industry has its own set of transaction patterns and risk levels (potential for fraud). Issuing banks utilise MCC codes to assess whether or not to accept a transaction. Online gambling, for example, is only legal in the states of Delaware, New Jersey, and Nevada. The code 7995 can be used to block transactions from states where online gaming is prohibited. The merchant's processing rates may also be affected by MCC codes. An incorrect classification could result in a merchant paying more processing fees than necessary. There are about 500 different MCC Codes used by Visa, and it is vital for a merchant to make sure they are assigned to the correct code. In order to track and restrict transactions, payment companies employ merchant category codes to identify merchants and enterprises based on the sort of goods or services they supply. Tax reporting, interchange marketing, and data collection on cardholder purchase trends are all possible uses for MCCs.
