Where the data comes from
What's behind each report and each free tool on this site, and the limits worth knowing about.
Carfax reports
Every report is compiled by CARFAX, Inc. from the records it collects, which include state motor vehicle departments, insurance companies, police accident reports, service and repair shops, auto auctions and manufacturers. We obtain each report through our data provider when you run a VIN, and deliver it to you unchanged, as the PDF Carfax produces.
A report can only show what has been reported to Carfax. An accident settled privately, or a repair paid for in cash, may never appear. The report says so itself, and it's why we suggest pairing it with an inspection by a mechanic you choose.
Free VIN decoder and vehicle details
The year, make and model we show before you buy, and the results of our VIN decoder, come from the vPIC database run by the US National Highway Traffic Safety Administration (NHTSA). It lists what the manufacturer reported for that VIN pattern, not the history of the particular car.
Recall check
Our recall check uses NHTSA's public recalls data for the vehicle's year, make and model. A dealer for that brand can confirm whether a recall has already been repaired on a specific car.
VIN validation
The VIN validator runs entirely in your browser. It applies the check-digit rule used on North American VINs, so nothing you type is sent anywhere.
Prices we compare against
When we quote another company's price, it's the price listed on their own website when we last checked: Carfax.com in September 2026 and AutoCheck.com in September 2026. Prices change, so treat them as a guide and check the seller's site before relying on one.
