A vehicle registration document contains key information to officially identify and register a vehicle. Typically, it includes:

• Vehicle details: such as the vehicle registration number (license plate), vehicle category or type, dimensions (length, width, height), engine displacement, engine power, seating capacity, and weight specifications (empty mass and permissible laden mass). It also often shows the Vehicle Identification Number (VIN), a unique 17-character number identifying the vehicle worldwide.
• Owner information: the name and address of the registered owner, and sometimes previous owners if relevant.
• Technical and legal data: details about the vehicle's approval, inspection due dates, technical modifications, type approval numbers, and sometimes emission standards.
• Registration status: information concerning registration, decommissioning, and re-registration history.

The document may be split into parts: Registration Certificate Part I (often carried in the vehicle) and Part II (proof of ownership, not typically carried with the vehicle). Part I includes the data needed when driving and for identification, and Part II is used for ownership proof and vehicle transactions. The document can also be used to ensure correct spare parts and modifications. This information is essential for law enforcement, ownership verification, and vehicle-related administrative processes.
