Up to 150 vehicle identification numbers may be granted during a calendar year. A vehicle identification number may be used for five years after it was granted. During the five years, the vehicle must be registered in Finland. If the vehicle is not registered during the five-year period, a new vehicle identification number must be applied for the vehicle from Traficom to register the vehicle in Finland as an individually manufactured vehicle.
