The sign says quality. The VIN says what it is.
VIN decoder
Paste a 17-character VIN and see the year, make, model, body, engine and assembly plant on file with NHTSA — then jump straight to that vehicle's recalls, complaints and crash ratings. Free, no sign-up, and the VIN goes only to NHTSA's decoder, never to WhichTrim.
17 characters. The letters I, O and Q never appear in a VIN. Find it on the driver's-side dashboard, the door jamb, your insurance card or the title.
A decoder for each make
Source: manufacturer codes, models, window stickerWhere the number is
Dashboard, driver's side
Stamped on a plate at the base of the windshield, readable from outside. Required there on every vehicle since the 1969 model year.
Door jamb label
The certification label on the driver's door or B-pillar repeats the VIN with the build date and gross weight ratings.
Paperwork
The title, registration and insurance card all carry it, as does the window sticker if you still have it.
What a VIN decode cannot tell you
Source: free federal toolsEverything the decoder shows is what the manufacturer built and filed with the federal government. What happened afterwards — title brands, odometer readings at each transfer, insurance total-loss and salvage records — lives in state DMV records, which reach the public through the federal NMVTIS system. WhichTrim does not sell those reports and takes no commission from anyone who does.
Recalls for this exact VIN
Decode it above and the WhichTrim recall report lists every recall filed against its build, sets aside the ones that name a different engine or drive, and narrows the rest to its build month off the door-jamb label.
Decode a VINBefore you buy it
The Car Check reads the model year’s whole federal record for you: the verdict, what breaks and at what mileage, whether the maker pays, and the year to buy instead.
The Car Check, $9.99After you own it
Add the car to a free Garage and WhichTrim emails you the day a new recall, bulletin or coverage extension is filed against it.
Your GarageOriginal MSRP, trims and warranty by VIN
When a decode matches a model year on file, the result shows every trim the manufacturer priced, the launch MSRP of the trim this VIN carries where NHTSA filed one, and the warranty terms — from the press kit, with the document on each row.
A decode is one moment. A recall can land next month.
Campaigns are filed every week against model years already on the road. Recall Watch re-checks your vehicle against the federal record every night and emails you the morning something changes — with the severity, any park-outside or do-not-drive flag, and both links that can settle it for your VIN. On the 1st of each month it sends a statement for the month just ended.

The free tier is the whole product, not a trial — no card, no clock, and every feature the paid plans have — alerts, the dated log, the monthly statement, the per-vehicle disclosure document and webhook delivery. Paid plans exist only because some people have more than ten vehicles.
How a VIN is put together
Source: ISO 3779 / NHTSA| Position | Section | What it tells you |
|---|---|---|
| 1–3 | World manufacturer identifier | Who built it and where. 1, 4 and 5 are the United States, 2 Canada, 3 Mexico, J Japan, K South Korea, W Germany, S the United Kingdom. |
| 4–8 | Vehicle descriptor | Model, body style, restraint system, engine — the section that makes a VIN say which car this is rather than which unit. |
| 9 | Check digit | A checksum of the other sixteen characters. A VIN that fails it has been mistyped or invented. |
| 10 | Model year | A letter or digit, not the year itself: N is 2022, P 2023, R 2024, S 2025, T 2026. I, O, Q, U and Z are never used. |
| 11 | Assembly plant | The manufacturer's code for the factory that built this vehicle. |
| 12–17 | Serial number | The unit's own sequence number on that line. |
How to read a VIN: what each of the 17 characters means
The federal rule behind the vehicle identification number: where to find it, what each of the 17 positions records, how the check digit catches a miscopied character, and what a VIN cannot tell you.

Common questions
Source: NHTSA vPIC, 49 CFR Part 565Is this VIN decoder free?
Yes, and it does not ask for an email. The decode comes from the U.S. National Highway Traffic Safety Administration's public vPIC database, the same record manufacturers file with the federal government.
Does WhichTrim store my VIN?
No. The lookup runs in your own browser and goes straight to NHTSA. The VIN is not sent to WhichTrim, not logged and not stored — reload the page and it is gone.
Can I find recalls by VIN?
A VIN decodes to a specific year, make and model, and this page then links you to that vehicle's page here, which lists every NHTSA recall campaign with its severity and whether a repair exists yet. Whether one applies to your individual car depends on its build range, so confirm the VIN itself at nhtsa.gov/recalls before acting.
What does each character of a VIN mean?
Every vehicle sold in the U.S. since 1981 has a 17-character VIN with a fixed structure: manufacturer, vehicle description, a check digit, model year, plant and serial number. The table above breaks it down position by position.
Why does the decoder not show my trim?
Manufacturers are only required to file the vehicle descriptor section, so trim is optional and many VINs decode without it. Where a trim is missing, the model-year page here lists every trim the manufacturer published, with specifications and MSRP, so you can identify it from the equipment.
Does this show accidents, title brands or the odometer?
No. A decode describes what the vehicle is — what the manufacturer built and filed. What happened to it afterwards (title brands, odometer readings, accident and salvage records) lives in state DMV records, which reach the public through NMVTIS-approved report providers. WhichTrim does not sell those reports.
Can it decode a motorcycle, an RV or an ATV?
Yes — the same database holds them, and each has its own page here with the fields and the recall authority that apply: motorcycles, RVs and trailers, ATVs and UTVs, and classics, including pre-1981 serial numbers.
