A Merchant Category Code (MCC) is a four-digit number used by credit card companies to classify a business by the goods and services it provides. When activating a Square Point of Sale account, you will set your MCC by selecting a business type. Your MCC code should directly reflect the type of business that you conduct, especially because it can influence card acceptance. For example, a veterinary clinic should select the merchant category code Veterinary Services. Square will also use this information to provide you with the best features to help grow your specific business.
If you’re not a business, you can state that you’re using Square as an individual or you can select a specific business type to best reflect the goods or services you provide.
If you’re having trouble accepting payment cards and you believe it’s because your business is incorrectly classified, contact us for assistance.
