To check a VIN, first make sure the VIN on the car matches the title, then decode it to confirm the make, model and year. Next check open recalls with NHTSA and theft or total-loss records with NICB's free VINCheck. All of this is free; a paid history report adds accidents, ownership and mileage.

1. Check the VIN matches
Compare the VIN on the dashboard, the driver door-jamb label and the title or registration. All three should be identical. A mismatch, a loose plate or scratched characters are reasons to walk away or get the car inspected.
2. Validate and decode it
A 17-character VIN never contains I, O or Q, and its 9th character is a check digit calculated from the others. The free VIN decoder checks both, then shows what NHTSA's vPIC database says the vehicle is. If it decodes to a different model, engine or year than the seller described, ask why.
3. Check recalls (free, NHTSA)
Enter the VIN at nhtsa.gov/recalls to see safety recalls that haven't been repaired on that vehicle. Our decoder lists the recalls issued for the model year, but only NHTSA's VIN search shows whether this particular car has had the work done.
4. Check theft and title status
- NICB VINCheck (nicb.org/vincheck): free; shows whether participating insurers reported the vehicle stolen and not recovered, or declared it a total loss.
- NMVTIS (vehiclehistory.bja.ojp.gov): the federal title database for brands such as salvage, junk or flood; reports cost a few dollars from approved providers.
When a paid history report is worth it
Free government data can't show accidents that weren't total losses, the number of owners, odometer readings over time or service history. For a used car you're about to buy, a paid vehicle history report fills those gaps, and a pre-purchase inspection by an independent mechanic checks what no report can.
FAQ
How can I check a VIN for free?
Decode it to confirm what the vehicle is, check open recalls at nhtsa.gov/recalls, and check theft and insurance total-loss records with NICB VINCheck. All three are free.
What is NMVTIS?
The National Motor Vehicle Title Information System, run by the U.S. Department of Justice. It holds title brands such as salvage or flood from state DMVs; reports are sold through approved providers for a few dollars.
Do I need a paid vehicle history report?
Free checks cover identity, recalls, theft and some total losses. A paid report adds accident, ownership, mileage and service records, which matters most for a used car you are about to buy.
