Plate to VIN
How to find a car's VIN from a license plate
A license plate is not a key to a car's history: in the United States every title, brand, odometer and theft record is filed against the VIN, and the plate is only a registration that can move from one car to another. The good news is that the VIN is easy to get. It is stamped on the car in five places, printed on every document that identifies it, and published in any listing worth trusting.
Look up a VIN by license plate
Five places the VIN is on the car
If you can stand next to the car, you do not need the plate at all. Manufacturers are required to put the VIN where it can be read without dismantling anything:
- Through the windshield, at the driver-side corner of the dashboard. This is the one the law requires to be visible from outside, and it reads perfectly well in a photo taken through the glass.
- On the sticker in the driver's door jamb. Open the door and look at the pillar the latch closes against - the same label usually carries the tire pressures and the month the car was built.
- Stamped into metal in the engine bay, most often on the firewall, a strut tower or a riveted plate. A stamping is far harder to fake than a sticker, which is why it is worth finding.
- On the frame or chassis: the front rail near the radiator on pickups and body-on-frame SUVs, or under the carpet on the passenger-side floor on some cars.
- In the trunk, under the spare-wheel well or the floor mat, on a good many models.
Read them against each other, then against the paperwork. On an honest car the seventeen characters are identical everywhere; a sticker that disagrees with a stamping is the most useful thing a non-specialist can find, and it is a reason to walk away rather than to negotiate.
The documents that carry the VIN
Every document that identifies the vehicle prints the VIN in full, usually at the top and often next to the plate number:
- The certificate of title. The VIN is what the document is about; the plate number is frequently not on it at all.
- The registration card, which normally lives in the car.
- The insurance card or the policy schedule.
- The listing itself: dealers and the larger marketplaces publish the VIN on the listing page, and many include it in the photographs.
A VIN never contains the letters I, O or Q. If you read one, it is a 1 or a 0 - and the VIN field on this site corrects that for you automatically.
Asking the seller, and what a refusal means
If the car is not in front of you, ask for the VIN. It is not private information: it identifies the vehicle and not its owner, and a seller who is advertising the car is already publishing it. Ask for a photo of the windshield corner and of the door-jamb sticker rather than a number typed into a message, so that you get the VIN and the evidence it belongs to that car at the same time.
A refusal is information too. The VIN is visible through the windshield of every car built since 1981, so declining to show it is a choice. Treat it exactly as you would treat a refusal to show the title.
The official route: a state DMV record request
There is one lawful way to turn a plate into vehicle-record data in the United States, and it runs through the state that issued the plate. Every state motor-vehicle agency has a records-request procedure: the names and the forms differ, the shape does not - you supply the plate or the VIN, you pay a fee, and you state what you want the record for.
That last part is the constraint. Access to motor-vehicle records is restricted by the federal Driver's Privacy Protection Act and by each state's own rules, and the form makes you certify one of the permitted uses: insurance business, a court or law-enforcement matter, a safety recall, a licensed business verifying information a customer gave it, and a handful of others. Curiosity about a car you are thinking of buying is not one of them.
So the DMV route is the right one when you own the vehicle, when you are acting for an insurer, an attorney or a licensed dealer, or when you have the registered owner's written permission. For a private buyer it is the slow road to a dead end, and the sections above are the fast one.
Plate lookup on PriorMile
PriorMile looks up US license plates. Enter the plate and the state that issued it, and we return the VIN it is registered to - the VIN and nothing else. Not the owner, not the address, not the registration record. From there the free preview tells you which history records exist for that car, exactly as it would for a VIN you read off the windshield.
Two limits are worth knowing before you lean on it. Coverage is US plates; plates issued in other countries are not supported. And a plate is not a permanent identifier - it is surrendered, transferred to another vehicle and reissued state by state - so a lookup can come back empty, or return the car the plate used to be on. A VIN read off the car cannot be wrong in that way, which is why the sections above are still the better route when the car is in front of you: check the seventeen characters against what the lookup returns. What we do not do is the DMV route below. The motor-vehicle record behind a plate stays restricted, and we neither request it nor return it.
Plate and VIN questions
Can I look up a car by license plate on PriorMile?
Yes, for US plates. Enter the plate and the state that issued it and we return the VIN, which you can run through the free preview like any other VIN. The VIN is all that comes back - no owner, no address, no registration record. Because a plate can be reissued or moved to another vehicle, check the VIN we return against the one in the windshield corner whenever you can see the car.
Is a license plate lookup legal in the United States?
Reading a plate is. Obtaining the vehicle record behind it is restricted: the federal Driver's Privacy Protection Act limits who may receive motor-vehicle records and for what purpose, and a state DMV request form makes you certify a permitted use. Wanting to check a car you might buy is not one of them on its own.
Can I get the VIN from a plate for free online?
On this page you can, for US plates: the lookup is free and needs no account, and it returns the VIN. Elsewhere, be careful - registration data is not public, so a free site that does not have it will show you a decoded guess or an advert instead. And if the car is in front of you, reading the VIN is faster than any lookup: look through the windshield, or open the driver's door.
Why is a car's history filed under the VIN and not the plate?
Because the VIN stays with the car for its whole life and the plate does not. Plates are surrendered, transferred to another vehicle and reissued by each state independently, so a plate identifies a registration rather than a car. Titles, brands, odometer readings, recalls, liens and theft records are all reported against the VIN.
