How to check for odometer rollback by VIN
NHTSA estimates that more than 450,000 vehicles are sold each year with false odometer readings. You cannot see a rollback on the dash, but you can compare the reading with the records tied to the VIN, the paperwork and the wear on the car.

What odometer rollback is
NHTSA defines odometer fraud as disconnecting, resetting or altering a vehicle’s odometer to change the miles it shows. It is a crime. A car that seems to have fewer miles sells for more, so the buyer overpays for miles they cannot see.
Digital odometers are not safe from it. NHTSA says a tampered digital odometer is even harder to spot than a mechanical one.
Compare the mileage records
| Record | What it shows |
|---|---|
| Title | The mileage the last seller wrote down at transfer, and any note that the reading is wrong |
| NMVTIS report | The most recent odometer reading in the state title record |
| Paid history report | Readings from other sources the provider collects, such as service and repair records |
| Service and inspection records | Dated mileage from oil changes, repairs and state inspections |
| Stickers in the car | Oil-change and maintenance stickers on windows and door frames, in the glove box or under the hood |
Line the readings up by date. Mileage should only go up. Any record that shows more miles than the odometer does today is a red flag. Look closely at the title too: NHTSA says to examine it carefully if the mileage figure looks obscured or hard to read.
NHTSA’s advice is to get a vehicle history report and check it for odometer discrepancies, using the VIN if the seller does not have one.

Check the car against the miles
- Tires. NHTSA says a car showing 20,000 miles or less should still have its original tires.
- Pedals and wear. Wear on the gas, brake and clutch pedals should fit the miles on the odometer. So should the rest of the car.
- Stickers. Oil-change and service stickers often record the mileage at each visit.
Then have an independent mechanic inspect it. The FTC says a history report is not a substitute for an inspection. Our used car checklist by VIN has the full list, and you can decode the VIN and run a free recall check while you are at it.
Federal odometer disclosure rules
When ownership changes, federal law requires the seller to give the buyer a written mileage disclosure on the title. If the mileage is incorrect, the law requires a statement saying so on the title.
Not every car needs one. Under 49 CFR 580.17, model-year 2010 and older vehicles are exempt once they are 10 years old, which covers all of them today. Model-year 2011 and newer vehicles need the disclosure until they are 20 years old, so the first exemptions for them start in 2031. Vehicles over 16,000 lb gross vehicle weight rating are exempt too. On an older car, the paper trail and the wear matter even more.
The same title and NMVTIS report also show brands. If either shows one, read what salvage and rebuilt titles mean.
If you suspect a rollback
Before you buy, walk away. After you buy, file an individual case with your state’s odometer enforcement agency. NHTSA cannot take on claims for individual buyers and advises consulting a private attorney about your rights.
For a large-scale scheme, call NHTSA’s Vehicle Safety Hotline at 888-327-4236 (TTY 888-275-9171). NHTSA’s Office of Odometer Fraud Investigation works cases for criminal prosecution by the Department of Justice.
FAQ
Can I check for odometer rollback by VIN?
You can check the VIN’s records for mileage that does not add up. An NMVTIS report shows the latest odometer reading in the state title record, and paid history reports can list readings from other sources. A reading lower than an earlier record is a red flag. No VIN check proves the mileage is right.
Can digital odometers be rolled back?
Yes. NHTSA says tampered digital odometers are even harder to detect than mechanical ones, because there are no moving parts to give it away. The car’s condition and a detailed history report are the best clues.
How common is odometer fraud?
NHTSA estimates that more than 450,000 vehicles are sold each year in the US with false odometer readings, and puts the chance of odometer fraud in the first 11 years of a vehicle’s life at 3.47 percent.
Which cars are exempt from federal odometer disclosure?
Under 49 CFR 580.17, model-year 2010 and older vehicles are exempt once they are 10 years old, so all of them are exempt today. Model-year 2011 and newer vehicles need a written disclosure until they are 20 years old; the first of those, model year 2011, become exempt in 2031. Vehicles over 16,000 lb GVWR are also exempt.
What do I do if I bought a car with a rolled-back odometer?
File a case with your state’s odometer enforcement agency. NHTSA cannot pursue claims for individual buyers and advises talking to a private attorney about your rights. Large-scale schemes can be reported to NHTSA’s Vehicle Safety Hotline at 888-327-4236.
