You went to a gas station, swiped your card at the pump, and saw two charges appear on your credit card statement by the time you finished pumping. The first charge was $50.00 from “SHELL OIL 57442 GAS” with code 5542, and the second was $42.15 from the same station. The same gas, two different charges, two different codes appearing on your statement.
You are a sole proprietor who drives for business and you want to know which one to categorize on Schedule C Line 9 (Car and Truck Expenses) and which one your fuel rewards card is supposed to apply to.
MCC 5542 is the 4-digit merchant category code assigned by Visa, Mastercard, American Express, and Discover to merchants that operate automated fuel dispensers (unattended gas pumps that accept payment directly at the pump). The 5542 code is closely related to MCC 5541 (service stations) but applies specifically to the at-pump, pre-authorization transaction.
When your credit card has been used at a self-service gas pump, the first charge you see is a pre-authorization hold from the automated dispenser (5542), and the second charge is the final transaction after the pump calculates the actual fill amount.
The merchant’s payment processor registers both the at-pump terminal and the in-store cashier separately, and the 5542 code applies to the at-pump terminal specifically.
Quick Answers: MCC 5542 is the code for automated fuel dispensers (gas pumps that accept payment directly, no cashier). It’s separate from 5541 (service stations, cashier-attended) because of the at-pump pre-authorization mechanic: a hold appears first, then the actual fill amount replaces it. The same gas station may have both codes depending on whether you paid at the pump (5542) or at the cashier (5541).
Schedule C Line 9 (Car and Truck Expenses) maps both 5541 and 5542 charges to the same line. Reward cards treat 5542 and 5541 differently in some cases, with the 5541 cashier transaction generally qualifying for fuel rewards more reliably. The pre-auth mechanic also creates a “hold then final charge” pattern that may appear as two transactions, which bookkeepers should reconcile properly.
What MCC 5542 Actually Covers
MCC 5542 is the merchant category code for “Automated Fuel Dispensers” in the ISO 18245 standard. The card networks use 5542 when a merchant operates unattended fuel pumps that accept payment directly at the pump without a cashier. The merchant’s payment processor registers the at-pump terminal as 5542, while the in-store cashier register may be registered as 5541.
The two codes can apply to the same physical gas station depending on where the customer paid.
