Why MCC Codes Matter for Your Business
Your MCC code directly affects how card networks and processors treat your transactions.
Approval Rate Impact
Processors have different acceptance rates per MCC. A misclassified code can silently tank your approval rate by 5-15%, costing revenue on every declined transaction.
Interchange Fees
The interchange fee you pay on every transaction is directly tied to your MCC code. Some categories pay 0.5% less per transaction — at scale, that compounds into significant savings or hidden costs.
Chargeback Thresholds
Visa and Mastercard set different chargeback monitoring thresholds per MCC category. High-risk MCCs face stricter limits — exceeding them triggers fines, reserve requirements, or account termination.
Wrong MCC = Serious Risk
An incorrect MCC assignment means you could be paying inflated fees, hitting the wrong chargeback program, or worse — facing account termination for "MCC mismatch" during a processor audit.
