When a car or van is registered in the Belgian vehicle register, the Federal Public Service for Mobility & Transport forwards the chassis number (VIN) and some official technical data such as the Euro standard and the CO₂ emissions to Car-Pass. Once the vehicle is in the Car-Pass database, automotive sector companies can forward the odometer readings and work descriptions.

The Car-Pass odometer reading and maintenance history comes from many different sources: garages, body shops, fast-fitters, tyre companies, technical inspections, etc. After any maintenance, repair, assembly or inspection work has been carried out, they forward the odometer reading and the description of the work carried out to Car-Pass. The inspection centres forward the odometer reading to Car-Pass when a car or van undergoes a technical inspection. 

Since 1 January 2020, car manufacturers are obliged to share with Car-Pass odometer readings for their connected vehicles (that are registered in Belgium) four times a year. There is no comparable legal obligation in any other European country. 

The odometer readings and work carried out for each chassis number are stored in our database. This means every vehicle builds up its own odometer and maintenance history.

When a Car-Pass document is requested, Car-Pass consults a number of other sources in real time. The importer/vehicle manufacturer will check whether there are any recalls that still need to be carried out. If so, they will be stated on the document.

The Car-Pass also consults the Informex database to see whether the vehicle has yet to undergo a Post-Accident Vehicle Inspection.

If the application is for an imported used vehicle, Car-Pass will request the available foreign odometer history from the importer/vehicle manufacturer. If the car or van comes from the Netherlands, the RDW (the equivalent Dutch database) will also be consulted. The Dutch odometer history will also appear on the Car-Pass.
