How to check a VIN before buying a used car: the free checks, and what each one cannot see

Updated November 1, 2026 · by POC Card

Before you pay for any report, there are three checks you can run on a used car’s VIN for free, in about ten minutes. Each one answers one question, and each source says on its own site what it does not see.

This guide goes through them in order, then the two things no website can do for you: looking at the VIN on the car itself, and having a mechanic look at the rest.

1. Get the VIN before you go

Ask the seller for the 17-character VIN when you first write to them. A private seller or a dealer with nothing to hide gives it in one message. If they will not, that tells you something before you drive anywhere.

A VIN never contains the letters I, O or Q. If a character looks like one of them, it is a 1 or a 0.

2. Decode it and compare it with the ad

The VIN says how the vehicle left the factory: model year, engine, transmission, drive, body and plant. Decode it and put it next to the ad. An ad that says V6 and all-wheel drive on a VIN that decodes to four cylinders and front-wheel drive is a reason to ask, or to stop.

You can do it here, free and without an account. The data comes from vPIC, the database of the U.S. National Highway Traffic Safety Administration (NHTSA). After the lookup, we can email you a printable checklist for that car.

What a decoder cannot tell you: who owned the car, its mileage, accidents or recalls. That is what the next checks are for.

3. Open safety recalls: NHTSA

Enter the VIN at nhtsa.gov/recalls. It shows unrepaired safety recalls for that vehicle, or the message “0 unrepaired recalls associated with this VIN.” NHTSA says recall repairs are always free at authorized dealerships, parts and labor included.

What it does not show, in NHTSA’s own list: recalls already repaired, recalls more than 15 years old (unless the manufacturer offers more), recalls from some small manufacturers, non-safety service campaigns and vehicles built for other countries. New recalls can take a while to reach every VIN, so check again close to the day you buy.

An open recall is not a reason to walk away; it is a free repair. Ask the seller to have it done before you buy, or book it yourself. NHTSA also warns that owners of used cars may not receive recall notices, so sign up for its alerts once the car is yours.

4. Theft, salvage and flood: NICB VINCheck

The National Insurance Crime Bureau’s VINCheck is free and tells you whether the vehicle was reported stolen and not recovered, or reported as salvage or flood-damaged, by participating insurers. NICB says those insurers represent 92.49 percent of the earned insurance premium in the U.S. (as of August 2026). You can run five searches per 24 hours from the same internet connection.

A “salvage” result means an insurer declared the car a total loss. It can still be legally rebuilt and retitled, but you want to know before you negotiate.

NICB is blunt about the limits: VINCheck only sees insurance records from participating companies, not police records, and it is not a full vehicle history report. A clean result is not a guarantee.

5. Title brands and odometer: NMVTIS

The National Motor Vehicle Title Information System is run for the U.S. Department of Justice. A report shows the vehicle’s title information, its most recent odometer reading, its brand history (labels such as “junk,” “salvage” or “flood” that states put on a title) and, in some cases, theft data. It is not free: each provider sets its price, and you buy it from one of the approved NMVTIS data providers listed on the official site.

This matters because a car flooded in one state can be dried out and retitled in another state that does not brand flood vehicles. NMVTIS exists to stop that. The site also explains that a report is intentionally short, that not every entity reports yet, and that a search can come back clean when it should not. States also brand titles differently.

6. Look at the VIN on the car

Everything above checks a number. Now check that the number belongs to the car in front of you. Read the VIN in three places and compare all 17 characters:

• at the bottom of the windshield, on the driver’s side, from outside;
• on the sticker in the driver’s door frame;
• on the title the seller will sign over to you.

If they do not match, or a plate or sticker looks scratched, re-glued or replaced, do not buy that day. NMVTIS describes “cloned” cars: stolen vehicles given the VIN of another car of the same make, model and year. An online check on a cloned VIN can come back clean, because it is checking the other car.

Also check that the name on the title is the name of the person selling.

7. When a paid history report is worth it

The free checks do not see accidents that never became a total loss, or service history. A paid vehicle history report pulls from more sources. The Federal Trade Commission notes that such a report may list accidents and flood damage, but typically not mechanical problems.

A reasonable rule: if the car passed the free checks and you are about to make an offer, a paid report costs less than one surprise. If it failed one of them, you probably do not need to pay to know enough.

8. Have a mechanic look at it

No VIN check sees worn brakes, a slipping transmission or a leak. The FTC recommends paying an independent mechanic to inspect a used car, even one the dealer calls “certified,” and asking for a written report with a cost estimate for the repairs it needs. If a dealer will not allow an independent inspection, the FTC suggests going to another dealer.

Buying from a dealer: every used car on the lot must display a Buyers Guide that says whether it is sold “as is” or with a warranty. If it says “as is,” the dealer does not pay for repairs after the sale, and spoken promises are hard to enforce: get them written on the Guide.

The next buyer will ask you the same questions. What raises a used car’s value when you sell it is the service history: dates, mileage and receipts. Keep the spec sheet with its own link and QR code, a printable card for the glove box, the service history and an email before the next service: that is VIN Card, one payment per vehicle.
