Vehicle registration plates of the Netherlands are vehicle registration plates issued by the RDW (Dutch Vehicle Authority) .[1]
RDW vehicle registration plates are assigned bearing the same "number" which is a sequence of characters composed of letters and digits as that is shown on the vehicle's registration document. The numbering scheme used bears no relation to the place of a vehicle's registration or ownership, and numbers – which are issued in strict time order – identify the vehicle, not its owner. Thus, if a vehicle changes ownership, the registration number remains unchanged.
If the car is a taxi or built before 1977, it will have a blue number plate. Taxis will have a blue number plate because they pay a different amount of tax to let people into the car legally. If a taxi does not have a blue number plate on it, it is an illegal taxi and the driver will charge a lesser fare to the person in the car.
A trade plate is a temporary number plate used by motor traders or vehicle testers to save them the cost and time to register and tax every vehicle temporarily in their possession. If somebody has a trade plate on their vehicle, that number plate will be green.
