Start Registering and re-registering your vehicle

You can find information in the Register of Motor Vehicles (Motorregistret) on all vehicles registered in Denmark.

Among other things, you can use the Register of Motor Vehicles to:

  • ask the Motor Vehicle Agency (Motorstyrelsen) to determine the value of your vehicle in order to obtain Danish number plates and a Danish registration certificate for it
  • change owner information if you purchase a used car in Denmark.

How to proceed

Log in to the Register of Motor Vehicles:

  • Log in to TastSelv using NemID
  • Select Motor – Motorregistret 

Request valuation:

  • Select Registreringsafgift (Registration tax) and then Anmod om værdifastsættelse (Request valuation)
  • Fill out the screen images and select Godkend (Approve)
  • You can see your receipt in your Meddelelsesarkiv (Notification archive).

Change information when changing ownership:

  • Select Registrering (Registration) and Privat ejer/brugerskifte (Private owner/user change). Then click Start ejer/brugerskifte (Start user/owner change).
  • Enter the registration or chassis number.
  • Open the vehicle with control number or code parts 1 and 2 from the registration certificate.
  • Add any other users or owners who have given their authorisation.
  • Select the insurance company and then Anmod om forsikring (Request insurance).
  • Select Godkend registrering (Approve registration).
  • Pay.
  • Select Videre (Continue) and print the receipt.

If you buy a used vehicle with number plates, you as the new owner must change the owner of the vehicle in the Register of Motor Vehicles within 4 weekdays from the time of purchase.

If you buy a used vehicle that has been deregistered in the Register of Motor Vehicles, you must register it again within 4 weekdays.

If you sell a used vehicle, you should note that the new owner is required to change the owner of the vehicle in the Register of Motor Vehicles within 4 weekdays. If this is not done, you can ask the Danish Motor Vehicle Agency to deregister the vehicle.
