What to verify by VIN before you buy
The VIN is the one thing about a used car that the seller cannot restate in friendlier terms. Here is what it settles, and what it leaves open.
Read the VIN off the car, not off the listing
A VIN typed into an advert is a claim like any other. The point of checking one is that it comes from the vehicle, so start there. Federal rules put the number in at least two places you can reach without tools.
- Through the windshield. On passenger cars, multipurpose vehicles and light trucks, the VIN has to be inside the passenger compartment and readable through the glass from a position next to the left windshield pillar (49 CFR 565.13(f)). In practice that is the plate at the driver's side corner of the dashboard.
- On the door jamb label. The federal certification label is fixed to the hinge pillar, the door-latch post or the edge of the door next to the driver's seat, and it must carry the VIN along with the month and year of manufacture (49 CFR 567.4). It is meant to be permanent: the rule says it cannot be removed without destroying or defacing it.
Then compare both against the title, the registration card and, if the seller has one to hand, the insurance card. All of them should be identical. If they are not, stop and get an explanation. There is an innocent version — a replacement door from a salvage yard carries the donor vehicle's label — and a serious version, covered in VIN cloning and fraud. Either way it is a question to resolve before money moves, not after.
Photographing the door jamb label is more reliable than transcribing seventeen characters by eye, and if it carries a barcode the decoder can read it with your camera. If you are buying remotely, ask the seller for that photograph rather than asking them to type the number. A mistyped VIN usually fails the check digit, but not always; see how the check digit works for the gaps.
Compare the decode against what you were told
Manufacturers are required to give NHTSA the information needed to decipher their VINs (49 CFR 565.16), and that is what a decode reads back. Where it disagrees with the listing, one of the two is wrong.
| Field | Why it is worth checking |
|---|---|
| Model year | The single most common discrepancy, and often honest. Under the federal definition, model year is the manufacturer's designation for a model, “irrespective of the calendar year in which the vehicle was actually produced”, so a car built and sold in late 2019 may be a 2020 model. The door jamb label shows the month and year it was built. A gap of more than one year is a different matter. |
| Trim and series | The field most often overstated, because trim drives price. Note that vPIC records what the manufacturer filed, which is sometimes coarser than the badge on the trunk. |
| Engine and displacement | Hard to misremember, easy to misrepresent, and expensive to get wrong if you are buying for a specific drivetrain. |
| Drive type | Front, rear or all-wheel drive is a material difference in winter climates and in resale value. |
| Body class and doors | A quick sanity check that you are looking at records for the car in front of you rather than a mistyped VIN that happened to decode. |
| Plant | Position 11 identifies the plant of manufacture. It occasionally contradicts a seller's claim about where a car was built. Rarely decisive, but free to check. |
A decode that disagrees with the listing is not proof of bad faith. Plenty of private sellers are simply wrong about their own car. It is a reason to ask one more question.
Read the recall list, then check the status yourself
Decoding a VIN here returns the safety recall campaigns NHTSA lists for that year, make and model. Read that as the set of things that could be outstanding on this vehicle. The list we draw on is organized by model, while a recall itself covers a defined population: one 2024 filing, for example, covers 2018–2020 Ford Expedition and Lincoln Navigator vehicles built between 1 October 2018 and 30 June 2019, not every one of them. A listed campaign may not apply to the car you are looking at, and if it does, it may have been repaired years ago.
To close that gap, run the VIN through NHTSA's own recall lookup, which reports unrepaired recalls on that one vehicle. Know its limits before you rely on a clean result. NHTSA says the VIN search does not show:
- safety recalls more than 15 years old, unless the manufacturer offers more coverage;
- some recently announced recalls for which not all VINs have been identified yet;
- recalls from small manufacturers, including some specialty brands;
- customer service or other non-safety campaigns;
- recalls involving international vehicles.
Tires and car seats are recalled separately and are not part of the VIN search. NHTSA also notes that VINs are added continuously, so a check made the week you buy is worth more than one made a month earlier.
An unrepaired recall is worth knowing about but is not usually a reason to walk. NHTSA's advice is to contact your local dealership, and the manufacturer has to remedy the defect without charge — by repair, replacement or a refund less depreciation, at its choice (49 U.S.C. 30120). There is one limit worth knowing on an older car: the free-remedy obligation does not apply if the vehicle was first bought more than 15 calendar years before the recall notice or order (5 years for tires). Ask for paperwork showing completed recall work. What matters more than an open recall is a seller who knew and did not mention it. Our guide to getting a recall repaired covers the practical side.
What a VIN decode will not tell you
This is the part worth being blunt about, because the category it sits in is full of sites implying otherwise.
Nothing on this site gives you title history, title brands such as salvage or flood, accident records, odometer readings, lien status, theft records or how many people have owned the car. Those records exist, but they are not in the NHTSA databases this site uses.
- Title and brand history comes through the National Motor Vehicle Title Information System (NMVTIS), run under the Department of Justice. An NMVTIS report deliberately covers five things: the current title state and date, the history of title brands applied by any state, odometer readings, total loss history and salvage history. It does not cover repairs, maintenance or recalls. Consumers buy reports from approved providers listed at vehiclehistory.bja.ojp.gov; the DOJ site lists them alphabetically, says the order implies no preference, and does not set prices. We have no arrangement with any of them.
- Theft and salvage records can be checked at no cost through the National Insurance Crime Bureau's VINCheck. It looks for vehicles reported stolen and not recovered, or reported as salvage, by participating NICB member insurers. It does not query law enforcement records, it allows five searches per 24 hours from one IP address, and NICB itself says it is not a comprehensive history report. It is free and takes a minute.
- Mechanical condition is not in any database. A pre-purchase inspection by an independent mechanic finds things no record holds.
Why title brands matter: the DOJ's NMVTIS pages describe how a brand can be “washed” by retitling a vehicle in a state that does not check its history, and NMVTIS exists partly to keep every reported brand visible. A recent title from a state with no obvious connection to the car is worth a question. Equally, a clean report is not a guarantee; the same pages warn that a search can give a false negative and encourage an independent inspection.
A reasonable order of operations
- Get the VIN off the car itself, from the windshield and the door jamb label, and check it against the title and registration.
- Decode it and compare every field against the listing and against what the seller told you.
- Read the recall campaigns, then check per-vehicle status with NHTSA.
- Run the free NICB VINCheck.
- Buy an NMVTIS title history report from an approved provider, especially if anything so far gave you pause or the title came from another state.
- Pay a mechanic to inspect it.
The first four are free and take about ten minutes between them. They will not catch everything. They will catch the cheap, common problems, which is a reasonable thing to ask of ten minutes.
Quick answers
Where is the VIN on a car?
In at least two places you can reach without tools. It is on a plate at the driver's side corner of the dashboard, readable through the windshield, and on the federal certification label at the driver's door jamb, which must also show the month and year of manufacture.
Does a VIN decode show accident or title history?
No. A VIN decode on RunThatVIN does not give title history, title brands such as salvage or flood, accident records, odometer readings, lien status, theft records or how many people have owned the car. Title and brand history comes through an NMVTIS report from an approved provider.
Is an open recall a reason not to buy a used car?
Not usually. The manufacturer has to remedy the defect without charge, by repair, replacement or a refund less depreciation, at its choice, but that does not apply if the vehicle was first bought more than 15 calendar years before the recall notice or order (5 years for tires). Ask for paperwork showing completed recall work.
Can I check if a car is stolen for free?
Yes. The National Insurance Crime Bureau's VINCheck is free and looks for vehicles reported stolen and not recovered, or reported as salvage, by participating NICB member insurers. It does not query law enforcement records, and NICB says it is not a comprehensive history report.
