It plays a crucial role in distinguishing each car, even those manufactured at the same factory or belonging to the same model.
The composition of the VIN number
The VIN number is subdivided into three basic segments:
WMI (World Manufacturer Identifier): A three-character code that identifies the geographical area, country, and manufacturer of the vehicle. For example, for French manufacturers like Renault or Peugeot, this code begins with « VF1, » while for Audi, based in Germany, it is « WAU. »
- VDS (Vehicle Description Section) : A six-character block that details the vehicle’s technical characteristics, such as the model, engine type, body style, and production location, according to a standardized coding system.
- VIS (Vehicle Indicator Section): The last eight characters uniquely identify the vehicle’s serial number, manufacturing plant, and model year. The first letter of the VIS indicates the production year, with « K » corresponding to 2019 and « J » to 2018, for example. What is the VIN number used for?
- The VIN number is essential for a multitude of vehicle-related operations. It is used to: Precisely identify a vehicle from all others.
Carry out procedures related to vehicle registration or insurance.

The VIN number (Vehicle Identification Number) is a unique 17-character code that precisely identifies each vehicle. It is essential for registration, insurance, purchase, repair, and technical support. This alphanumeric code includes several sub-sections that provide information about the manufacturer, model, year, and place of manufacture. Understanding it provides access to essential information for any owner or automotive professional. Definition and Composition of the VIN Number The VIN Number
is an internationally standardized identifier, established since 1981 for each motor vehicle. It consists of 17 alphanumeric characters, forming three specific segments: the WMI (World Manufacturer Identifier), the VDS (Vehicle Description Sector), and the VIS (Vehicle Identifier Section). Each segment has a specific role in describing the vehicle. WMI: Manufacturer Code The WMI corresponds to the first three characters of the VIN number. It geographically identifies the origin and manufacturer. For example, France is located in zone V, including brands like Renault (VF1) or Peugeot (also VF1), while Audi, based in Germany, uses the WAU prefix. These codes are assigned by the relevant authorities based on the manufacturer’s headquarters. VDS: Vehicle Descriptor CodeThe VDS is the intermediate part of the VIN number, comprising six characters. This technical segment details the vehicle’s precise characteristics: model, engine type, body style, and production location. This coding helps differentiate between variants and configurations of the same model.
The VIS: Individual Identification
The last eight characters of the VIN number form the VIS, which serves to uniquely identify each vehicle. This segment includes the serial number, the manufacturing plant, and the model year. For example, the first letter of the VIS indicates the production year: ‘K’ for 2019, ‘J’ for 2018, etc. It is important to note that the letters I, O, and Q are excluded from the VIN to avoid confusion with the numbers 1 and 0. Uses and Applications of the VIN NumberThe
