Used cars are a great way to save money on a new ride. However, there are downsides to buying a second-hand vehicle. If a deal sounds too good to be true, it’s likely an online car marketplace scammer or shady dealership selling a vehicle with hidden problems or rolled-back mileage. These issues can cost buyers unexpected repairs and even legal issues in the long run.

A free VIN check is an excellent way to avoid a potential scam. This user-friendly tool details a vehicle’s history, such as possible title issues and accident reports, and can help buyers feel more confident about their purchase.
The Vehicle Identification Number (VIN) is a 17-character set of numbers and letters assigned to each vehicle. This internationally standardized serial format is used to identify individual cars, trucks, and SUVs.
Once a vehicle is assembled and leaves the manufacturer’s factory, it receives its VIN, and no two cars can have the same VIN.
Most countries keep records of VINs and vehicle histories in their databases. In the United States, these databases include the National Motor Vehicle Title Information System (NMVTIS), state DMVs, and some private organizations. Every vehicle made since 1980 is required to have a VIN.
All VINs are made up of 17 characters, but the details they reveal can vary, depending on where the vehicle was manufactured. For instance, North American VINs are broken down into six segments:
The VIN can be found in several locations on a vehicle, including:
The VIN can also be listed on the vehicle’s title and registration or printed on the owner’s insurance card.
When a VIN is entered into a lookup tool, it unlocks detailed information about the vehicle’s history, helping buyers decide whether to make the purchase. While the information varies depending on the service used, most free VIN lookup tools offer:
There are a few services available online that offer free VIN checks. However, each one provides information with varying levels of detail, so buyers may need to use more than one to get a full view of the car they’re considering.
The JD Power VIN Lookup & Decoder is a free VIN lookup tool that gives buyers in-depth information about any vehicle. When buyers enter a car on the VIN Lookup & Decoder, the following details will be displayed:
The NICB is a nonprofit organization that is committed to fighting vehicle-related crimes like theft, arson, and insurance fraud. Buyers can access VINCheck®, a complimentary VIN lookup service on the website.
Because the organization is mainly focused on preventing fraud, VINCheck® only provides basic vehicle information, such as whether the VIN has been tagged as stolen or written off as a total loss (salvage record).
Although the NICB VIN lookups don’t go in-depth on vehicle details, they can still help buyers identify potential scam sellers.
CarFax is an established private provider of vehicle history reports in North America. The company provides access to some of the most detailed history reports, with a complete breakdown of the following:
CarFax reports are widely recognized for their comprehensiveness. However, the biggest drawback for an individual buyer is its cost. CarFax is primarily intended for professionals and does not provide a free version of its service.
Purchasing a used car can be risky without access to the right information. VIN lookup services are an essential step for many car buyers. The details a check provides help avoid potential scams and determine whether the vehicle is worth purchasing.
The JD Power VIN Lookup & Decoder is designed to be the first step in a used car buying experience. Find detailed information to make an informed purchase and stay safe from scams and fraudulent sellers.
