Where to start a used car VIN check
Decode a VIN
Check the 17 characters are valid, test the check digit and read the maker, region and model year.
Find the VIN
Dashboard, door jamb, title and insurance card. Make sure all of them match.
History reports
What paid reports pull together, and what they routinely miss.
Title brands
Salvage, rebuilt, flood, lemon and junk: what each word on a title means.
Free VIN checks from official sources
Run the VIN through the official sources before you pay for anything. Two of them are free and the third costs a few dollars.
Open recalls
NHTSA's recall lookup at nhtsa.gov/recalls is free and searches by VIN.
Theft and insurer total loss
NICB VINCheck at nicb.org/vincheck is free, with a small daily search limit.
Title and brand history
NMVTIS reports come from approved providers listed at vehiclehistory.bja.ojp.gov, usually for a small fee.
You need all three, because each covers something the others don't. The recall lookup knows nothing about accidents, VINCheck only sees data from participating insurers, and NMVTIS covers titles and brands but not repair history. Between them they catch the most expensive surprises.
What order to check a used car in
- Get the VIN before you travel. If the seller won't share it, you already have your answer.
- Decode it. The model year, maker and body should match the advert. If they don't, stop there.
- Run the free checks for open recalls, theft and insurer total-loss records.
- Look at the title history. An NMVTIS report or a full commercial history report shows brands, title transfers and recorded mileage.
- See the car in person. Match the VIN on the dashboard, door jamb and title, then work through the used car buying checklist.
- Pay for an independent inspection. Records show what someone reported. A mechanic can show you what is actually there.
What a VIN check can't tell you
A VIN check reads databases, and a database only holds what someone reported to it. A crash repaired privately for cash, a flood car moved to another state before an insurer got involved, or an odometer rolled back between two recorded readings can all leave a clean record. A clean report is one piece of evidence and should be weighed as that.
So the guides here pair the paper trail with things you can check on the car yourself: signs of odometer tampering, flood damage clues on the title brands page, and how to confirm the car isn't reported stolen.
How to read the 17 characters of a VIN
Each of the 17 positions records something: who built the car, what kind of vehicle it is, a check digit, the model year, the plant and a serial number. The position-by-position VIN guide covers all of them, including why the letters I, O and Q never appear.
VIN check questions
Is a VIN check free?
The NHTSA recall lookup and NICB VINCheck are free. An NMVTIS title report comes from an approved provider, usually for a few dollars. Full commercial history reports cost more.
Does a clean VIN check mean the car is fine?
No. It means nothing was reported to the sources that were searched. Cash repairs and some flood or mileage problems never reach a database, so you still need to inspect the car and have a mechanic look at it.
Can I check a car built before 1981?
Not with a modern decoder. The 17-character format applies from the 1981 model year, and older vehicles used manufacturer formats of different lengths.
