MCC 9402
Postal Services – Government Only
What is MCC 9402?
9402 is the Merchant Category Code for Postal Services – Government Only. It sits within government services — taxes, fines, courts and public-sector payments. Card networks — Visa, Mastercard, Discover and American Express — assign a four-digit MCC like this one to every business based on what it primarily sells, and it travels with each card transaction the business runs.
Who's assigned MCC 9402?
Businesses classified as Postal Services – Government Only are typically assigned MCC 9402 when their merchant account is boarded. Your payment processor sets the code based on how your business is described and what it sells — so a business whose primary activity matches this category will usually carry 9402.
How MCC 9402 affects your processing
Your MCC influences your interchange rates, how the card networks classify your risk, and which programs apply to you — reward categories, debit routing, and surcharge or cash-discount eligibility. For a standard-risk category like this, the thing that matters most is simply making sure your code is accurate and your markup over interchange is fair — that's usually where merchants quietly overpay.
