ATV & UTV VIN decoder
Off-road vehicles are not regulated by the highway safety agency, yet most makers file their 17-character VINs with NHTSA's database anyway, and those decode here. Paste the number from the frame and see the model year, maker, model and engine on file. Where the maker did not file, the page tells you so rather than guessing.
17 characters. Stamped into the frame — commonly the left front frame rail, under the front rack, or the footwell area — and printed on the certification label. The location varies by maker.
Where the number is
On the frame
Stamped into the frame tube: on many ATVs the left front rail or under the front rack; on side-by-sides often the frame near the driver's footwell or under the seat. The owner's manual gives the exact spot.
Certification label
A label on the frame repeats the VIN with the model year and, on UTVs, the gross weight rating.
Dirt bikes
As on a road motorcycle: the steering head, right side, behind the fork.
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.
Off-road vehicles are the Consumer Product Safety Commission's, not NHTSA's. ATV, UTV and dirt-bike recalls are published at cpsc.gov, and a decode here does not check them.
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.

Your GarageA 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 machine 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. |

Common questions
Source: NHTSA vPIC, 49 CFR Part 565, CPSCDo ATVs have VINs?
Most do. Makers commonly mark ATVs, side-by-sides and dirt bikes with a 17-character number in the same format as a road vehicle's VIN, and many file the decode with NHTSA's vPIC database even though NHTSA does not regulate off-road vehicles. That is why many decode here and a few do not.
Why did my ATV not decode?
Because the maker did not file that pattern with NHTSA, which they are not required to do for an off-road vehicle. The VIN is still valid — check it against the maker's own owner portal or dealer.
Where are ATV recalls published?
At the Consumer Product Safety Commission, cpsc.gov, not at NHTSA. Off-road vehicles are consumer products in federal law. The recall card below points there.
Where is the VIN on an ATV or UTV?
Stamped into the frame — commonly the left front frame rail or under the front rack on an ATV, and near the driver's footwell or under the seat on a side-by-side — and printed on the certification label. The owner's manual gives the exact spot for the model.
Is my VIN stored?
No. The decode runs in your browser against NHTSA's public database. WhichTrim never receives it.
