What is a Monroney label?
A Monroney label is the price sticker that federal law requires on the window of every new car sold in the United States. It has been mandatory since the Automobile Information Disclosure Act of 1958 — Public Law 85-506, signed 7 July 1958, effective 1 January 1959 — and is codified at 15 U.S.C. §§ 1231–1233. Removing it before the car reaches the buyer is a federal offence.

Everyone calls it the window sticker. It is the most information-dense document about a car you will ever be handed, and almost nobody reads past the total.
Where the name comes from
Senator Almer Stillwell “Mike” Monroney of Oklahoma sponsored the Act. Before it, a dealer could describe a car’s factory price as whatever was convenient, and many did. The law made a standardised price label mandatory on the window of every new car and made removing it before sale a federal offence. Sixty-eight years later people still call it a Monroney.
What it must disclose
The statute and the EPA/NHTSA labelling rules together set out what has to appear. Every one of these is on the sticker:
- Vehicle description — make, model, trim, engine, transmission and the VIN itself.
- Base MSRP — the manufacturer’s suggested price for the car with no options.
- Every factory option, individually priced — packages, single options and what each one cost.
- Destination charge — shipping from the plant, which is neither negotiable nor optional.
- Total price as delivered — the sum, and the number the dealer quotes against.
- Standard equipment and warranty — what came with the car at no extra cost, and the coverage terms.
- EPA fuel economy — city, highway and combined MPG (or MPGe for an EV), estimated annual fuel cost, and CO₂ grams per mile.
- Five-year fuel cost comparison — what this car costs to fuel against the average new vehicle.
- Government safety ratings — NHTSA crash-test results, where the vehicle was tested.
- Smog and greenhouse gas scores — the two 1–10 EPA ratings in the fuel economy panel.
- Parts content — the US and Canadian parts percentage and the major foreign sources.
- Final assembly point — and, separately, where the engine and transmission were made.
- A QR code — added with the 2013 label redesign; it opens fueleconomy.gov for that exact vehicle.
How to read one
Start at the bottom right. The total price is the number that matters and it already includes destination. Work upward through the options list: anything with a price beside it was an extra the original buyer chose and paid for. Standard equipment sits in its own block and costs nothing.
The EPA panel in the upper right is standardised across every manufacturer, which makes it the only genuinely comparable part of the label. The large number is combined MPG. The two smaller ones are city and highway.
Why it matters on a used car
The label is filed against the VIN rather than against the sale, so it usually stays retrievable years later. That makes it the cleanest way to confirm how a used car actually left the factory — which trim, which packages, what it originally cost. Sellers overstate trim levels constantly, sometimes honestly. The sticker does not.
It is also the fastest way to spot a car worth more than its listing suggests. A truck with the max tow package, or a sports car with the track package, carries thousands of dollars of hardware that never shows up in photos.
What it will not tell you
Nothing about the car’s life after it left the factory. No accidents, no title branding, no odometer history, no service records. For that you need a vehicle history report and, more importantly, an independent inspection. The Monroney is the birth certificate, not the medical file.
