To get an OBU, you will need to enter the following data:
You need to upload (on the Road User Portal) or scan (at a Service Point) a copy of all relevant documents providing proof of this data: your vehicle papers. See here under "Vehicle Papers" per country where you can retrieve these values from your vehicle documents.
It is important that the data you have entered on the Road User Portal or at the Service Point for your vehicle, matches the data specified on the vehicle papers. You can then be sure that the amount of toll you have to pay is correct and you will not receive any fine. We remind you that those who fail to comply with Belgian Road Pricing regulations risk a fine amounting to maximum of €1,000!
*In some cases, the EURO Emission Class is not indicated on the registration documents: please use the table entitled "Semi-trailer towing vehicles: Emission table when no euro norm is indicated", which may be found on the Viapass website.
