What is Vehicle Identification Number?

VIN, or Vehicle Identification Number, also known as chassis number, is a 17-character code that every vehicle receives at the production stage. The VIN is essential for motor vehicle registration, insurance, and tracking the vehicle's history. Based on the VIN, you can determine technical data about the car, and a paid vehicle history report will give you insights into its past, helping you avoid unpleasant surprises after purchase. The first three characters of the VIN are origin character codes identifying the country of origin, manufacturer, and category of the vehicle. This first three characters of the VIN are known as the World Manufacturer Identifier (WMI). Characters 10 through 17 of the VIN form the Vehicle Identifier Section, containing information such as the year the vehicle was built and the assembly plant. The VIN is like the DNA of a car – no two are identical. The VIN decoder is intended for use with vehicles manufactured since 1981.

How Does the VIN Decoder Work?

The VIN decoder analyzes each of the 17 characters of the Vehicle Identification Number, assigning them specific meanings. The eleventh character of the vehicle's VIN represents when and in which assembly plant it was built. This allows you to obtain basic information about the particular vehicle:

  • vehicle production location,
  • vehicle manufacturer — brand and model year,
  • year of production,
  • engine size,
  • body style,
  • factory equipment,
  • vehicle technical data,
  • drive type,
  • engine type.

The information displayed by the VIN decoder is based on information provided by the vehicle's manufacturer.

Why Use the VIN Decoder?

  1. Check if the VIN's World Manufacturer Identifier (WMI) is authentic

    With the decoder, you can verify the check digit to see if the given number meets ISO standards and is assigned to the correct vehicle manufacturer. Inconsistencies between the information provided in the advertisement and the VIN decoding results may indicate attempted fraud.

  2. Confirm the VIN matches the checked vehicle’s specs

    Confirming that the chassis number matches the vehicle is as important as it is to confirm its authenticity. The VIN decoder will not only decipher the basic technical data encoded in the VIN but it will also allow you to check if all the vehicle equipment elements match the manufacturer's factory data. You can also confirm the place and year of production.

  3. Check if the VIN has been tampered with/cloned

    Checking if the VIN appears in two vehicle registers can help determine if the vehicle is stolen and if VIN cloning has been carried out. Cloning is the practice of affixing the VIN of a legal vehicle on a stolen car that is the same model, model year, and has similar basic specifications.

  4. Check for service recalls on the vehicle.

    Over 60,000,000 cars on the road are subject to service recalls. Verify if the vehicle belongs to this group and has pending recall notices.

Where to Find the VIN

  1. Nameplate:

    This is a metal or plastic plate attached to the vehicle’s body, often located in places like the driver’s door sill, on the frame under the windshield (visible through the windshield), or under the hood.

    Often on the driver’s side door pillar, there is a sticker with the VIN.

  3. Dashboard:

    Look at the front of the dashboard on the driver’s side – the VIN is often engraved on a metal plate and visible through the windshield.

  4. Vehicle Documentation:

    The VIN number is always found in the vehicle documents: registration certificate, insurance policy, or service book.

  5. Chassis or Frame:

    In some vehicles, the VIN may also be stamped directly on the frame or chassis.
