Where Is the VIN Number on a Car? The Two Places to Look

Where is the VIN number on a car? In two places on every car, SUV and light truck sold new in the United States: a small plate you read through the windshield, and a label on the driver's door frame.

Two federal rules fix those spots, while other guides add more: under the hood, the firewall, the front of the frame. Those spots are real on some cars, but they change from maker to maker, so they come after the two every modern car must have.

Where is the VIN number on a car?

The VIN is in two required places: the bottom corner of the windshield on the driver's side, and the label on the driver's door frame. Both carry the same 17 characters, and reading both is how you catch a copying mistake.

The windshield spot is set for cars, SUVs, vans and pickups up to 10,000 pounds, so a heavier truck may keep its plate somewhere else. On anything lighter, both spots are there, and checking that they match takes a minute.

1. The windshield corner

Stand outside at the driver's door and look down through the windshield where the glass meets the dashboard. The number is on a small plate there, and you don't need to open the car.

The federal rule says it must be readable through the glass, in daylight, by someone standing outside next to the driver's windshield post. So you can copy it in a parking lot, even with the car locked.

2. The driver's door label

Open the driver's door and look at the edge of the frame it closes against. A printed label sits there, and the VIN is one of the lines on it.

The label goes on the door frame post or on the edge of the door itself, next to the driver's seat. It's made so it can't be peeled off in one piece, which makes it a good second check on the windshield plate.

This label is also where the build month and year live, which can settle what coolant your car needs when a carmaker changed it halfway through a model year. Its build date can differ from the model year.

How many places is the VIN on a car?

Two places are required, and many cars carry the VIN in a few more. Those extra spots change from maker to maker, and your owner's manual names them for your car.

Owner's manuals name spots such as the floor under the passenger seat, a frame rail, the engine block, a label in the glove box and an interior VIN under a cover. The makes and models behind each spot are in the records below.

Some cars also have the VIN marked on major parts such as the engine, fenders, doors and bumpers, under a federal theft rule. You aren't meant to find them. The markings sit on inside surfaces for investigators, so you won't spot them with the car together, and many vehicles carry none.

An engine or transmission may carry only the last eight characters. The eight-character mark isn't a mistake, but it won't run through a decoder.

If both required places are gone, say a missing windshield plate and a painted-over label, stop searching the car. On your own car, use the paperwork instead. On a car you're buying, it's the missing VIN case below.

How do you find the VIN without the car?

If the car isn't in front of you, the number is on paperwork you already have. Federal odometer rules require it on the title, and it usually appears on the registration and the insurance card.

Policy documents, the bill of sale and shop repair orders can carry it too. The insurance card is the handiest, and the title is the legal record.

What if the VIN is missing or doesn't match?

Stop before any money changes hands, because a missing or altered VIN can point to a stolen car. Federal law makes knowingly removing or altering one a crime, and New York's DMV says police will seize a vehicle with an altered or missing number.

Compare the plate, the door label and the title. If they don't agree, ask your state DMV or the police to check the car, and run the number through NICB's free VINCheck for reported thefts. Never repair or alter a plate yourself.

What does a VIN number look like?

On a car built since the early 1980s, a VIN is 17 characters with no spaces or dashes. Any other length on a modern car means you've found something else: an engine number, a paint code or a part number.

Older cars are the exception. The 17-character format became mandatory with the 1981 model year, so a 1974 pickup with an 11-character plate is showing its real VIN, just an older one.

People often call these the 17 digits, though some are letters. The drawing below uses the sample VIN printed in the federal rule itself.

The four parts, left to right

The rule splits the 17 characters into four blocks, and each answers one question about the car:

• Positions 1–3: who made it. The world manufacturer identifier: where it was assembled, the maker and often the type of vehicle.
• Positions 4–8: what it is. Body style, engine, restraint system and, on trucks, the weight rating.
• Position 9: the check digit. A calculated character that catches a mistyped VIN.
• Positions 10–17: which one. Model year, assembly plant, then the serial number. On a car or light truck, the last five are always numerals.

Most of the time you need only two of those blocks. The 10th character gives the model year, and positions 4–8 tell a parts counter which engine the car has.

What the first three characters say

Those three are the world manufacturer identifier, and NHTSA, the federal vehicle safety agency, publishes who each one belongs to. The first character is where the car was assembled, not where the brand comes from.

The country codes run 1, 4 or 5 for the United States, 2 Canada, 3 Mexico, J Japan, K South Korea, W Germany and S the United Kingdom. Newer US identifiers can also start with 7, such as Honda's 7FA.

One brand has many identifiers. A Honda built in the United States starts 1HG, the same badge built in Canada starts 2HG, and one shipped from Japan starts JHM.

Why a VIN never contains I, O or Q

The rule leaves three letters out of the allowed set: I, O and Q. They're too easy to read as 1 and 0 on a worn plate or in someone's handwriting.

So if you think you're reading an I or an O, you're reading a 1 or a 0. That one habit saves a rejected insurance or title form, and a second trip to the counter.

The check digit, and why two cars never share a VIN

Position 9 is a built-in typo check, a numeral or the letter X. The maker works it out from the other 16 characters, so one mistyped character usually breaks it, and NHTSA's decoder says so.

A check digit that works out proves only the math, not that the VIN belongs to this car. The rule also bars any two vehicles from sharing a VIN for 60 years. On most cars the last six characters are the serial number.

How do you tell a car's year from the VIN?

The 10th character is the model year, and a VIN year chart turns it into a year. The catch is that the codes repeat every 30 years, so A means 1980 and also 2010.

Position 7 tells the two apart. Since 2010 it must be a letter on cars and light trucks, so a numeral there puts the year in 1980–2009, and a letter in 2010–2039.

So a useful VIN year chart shows two years for each code. In the example drawn above, position 7 is a 9, so the 5 in position 10 means 2005 and not 2035.

The year position also never uses U, Z or the numeral 0, so a U there is a misreading. Like the rest of the VIN, it skips I, O and Q as well.

To read your year off the chart, find your VIN's 10th character in the middle column and look at its 7th character. A digit means your year is the one to its left, and a letter means it's the one to its right.

Model year isn't the year the car was built. A model year can run up to 24 months, so a car sold as a 2019 may have left the plant in 2018.

Can you read the VIN on a screen or a scan tool?

Yes, on newer cars. A scan tool reads it from the diagnostic port under the dash, and some dashboard touchscreens and carmaker apps display it too.

California's rule for that port, known as OBD-II, requires the VIN there on 2005 and newer models. A scan tool plugged in can then show it with the vehicle details.

On a Ford with SYNC, it's under Settings, then General, then About SYNC, and the Ford app lists it under vehicle details. On a Tesla, it's under Controls, then Software, on the touchscreen.

A screen reading is handy, but it's still worth matching it to the plate. The plate and the door label are the record that counts.

How do you check a VIN for free?

Two free federal tools check a VIN online, and they answer different questions. The decoder says what the car is, and the recall lookup says whether it has an unrepaired safety recall.

Both ask for nothing but the 17 characters. Copy them carefully first, with the steps below, because one wrong character can send either tool to the wrong car.

1. The VIN decoder

A free VIN run through the decoder shows you the factory specs the maker filed for that pattern: make, model, year, body, engine, fuel, plant and weight class. It describes the pattern, not your individual car, and it won't tell you the owner, the location, the crash history or the sale price.

Our free VIN decoder runs on the same federal database and adds one thing: what owners of that car complained to the government about, ranked by part. The VIN also gets the parts counter the part for your engine, which helps when you have a fault code to look up.

2. The recall lookup

The recall lookup is the one to run on every car you buy. A recall follows the car, so a used one may carry a fix the last owner never booked, with the letter sent to their address.

A dealer repairs a recall free whoever owns the car. The exception is a car first sold more than 15 years before the recall notice.

A model year can carry several recalls, so whether one is still open on a given car takes that car's VIN. A clean result can still miss a very new recall, one over 15 years old, or one from a very small maker.

How do you read and confirm your VIN?

Photograph the windshield plate, then match the door label to it, character by character. These 5 steps go in this order because each one checks the one before it:

1. Photograph the windshield plate. Stand at the driver's side and shoot it through the glass. A photo can be zoomed later, and a scribbled 5 can't.
2. Read the door label. Open the driver's door and compare its number with the photo, character by character.
3. Fix the look-alikes. Read every I as 1 and every O as 0, then double-check Z and 2, S and 5, and B and 8.
4. Run it through a decoder. Enter it in our free VIN decoder and check that the make, model and year match the car. A check digit warning usually means a typo, so go back to the photo.
5. Check it for open recalls. Enter the same 17 characters on NHTSA's recall page, linked in the documents below. Repeat it now and then on a car you keep, since new recalls keep coming.

A step can stop you, and each of these four has a next move:

• The plate is missing or unreadable. Use the door label and the title instead. On a car you're buying, stop and check it before you go on.
• The plate and the label don't match. Stop there and compare both with the title. If the title matches neither, ask your state DMV or the police before any money changes hands.
• The check digit warning won't go away. Re-read the photo for the look-alike pairs. If it still fails, the number you were given isn't a valid VIN, so ask for the title.
• The decoder shows a different car. Treat it like a mismatch: the title, the plate and the door label have to agree before anything else counts.

On a used car, the VIN is where the checks start. It tells you which engine you're being offered, and whether that's a wet belt engine can change what the car costs to keep.

Common questions

Asked most often

Where is the hidden VIN on a car?

A hidden VIN usually means the theft prevention marking federal rules require on major parts such as fenders, doors and bumpers. It's designed to stay readable once the part is off the car, so you can't reliably find it with the car assembled, and many vehicles don't carry it.

Is the VIN the same as a serial number?

On most cars the last six characters are the factory serial number, and the 11 before them describe the maker and the vehicle. An engine also has its own separate serial number.

Can I find a VIN from a license plate?

Commercial vehicle history sites sell plate-to-VIN lookups. For your own car you don't need one, because the registration that goes with the plate carries the VIN.

Where is the VIN on a trailer or a motorcycle?

Both must carry a VIN, but the windshield rule doesn't apply to them. The certification label that carries it goes on the forward half of a trailer's left side, and on a motorcycle near the steering post or handlebars.

Requirements described here are US federal rules, read in the Code of Federal Regulations on October 3, 2026, and they apply to vehicles built for sale in the United States. This article is general information, not advice about your specific vehicle. See the disclaimer.
