The website VINDecoder.net provides a free VIN lookup tool. This site covers the VIN numbers for 28 different car manufacturers, including all 10 of the most popular manufacturers according to Kelly Blue Book.
VIN Decoder does not provide any information on cars made by boutique manufacturers. Fortunately, a number of manufacturer-specific VIN decoder websites exist. For example, the site VINFreeCheck.com offers a VIN decoder tool for McLaren vehicles, which VIN Decoder does not cover. If a car has a public sale record, its VIN number is available for research through CarFax. This free service also provides a vehicles repair history and recall information.
