Vehicle registration plates in Denmark normally have two letters and five digits and are issued by authorities. Plates can be obtained at authorized car dealers, vehicle inspection stations or official registration centers (Skat Motor center). The combination is simply a serial and has no connection with a geographic location, but the digits have number series based on vehicle type.^[1][2]

Danish registration plates do not follow the owner or the vehicle. When a vehicle is traded in with a dealership, the plates are usually turned in. The reason is that if the dealership just changes the ownership to themselves, they will be charged for insurance and taxes until the vehicle is sold to a new owner. If the dealer already has a buyer on hand or if the vehicle is sold directly by the owner to a buyer, the ownership can be changed and the plates transfer with the vehicle. This way a vehicle can, in principle, keep the same plate for its entire lifespan. However, this is rare and most Danish vehicles have numerous plates during their lifespans. When the car is recycled, the plates are surrendered so that no plates are recycled with the vehicle, unlike in Sweden or the UK where the plates follow the vehicle, which can often be seen at a scrap yard with the plates still on.

On the number combination one can see the type of a vehicle before 2012. Numbering after 2012 is completely random in order to allow for more combinations. Exceptions from this are diplomatic vehicles still using "76" and "77" and taxis/limousines using "98" and "99" The letters have no significance and are random. You can no longer determine the type of vehicle from the first two digits after 2012.

Hearses are registered as yellow-plate cars (commercial use). The actual plates are, however, white (personal use), reflecting the view that the deceased is a passenger rather than commercial freight.

A new design with an EU stripe was expected in 2008, but was thereafter delayed to 12 October 2009.^[8] This makes Denmark potentially the last EU country to adopt euro plates (Vehicle registration plates of Europe). The EU stripe is, however, currently optional.^[8] In preparation for the new design, the plate font was slightly condensed on some new plates issued after mid-2008. Since July 2009, buyers of a car could pick a license plate with or without an EU strip.^[9]

If a Danish registered vehicle does not have the plate with the EU stripe then it must be equipped with an approved oval DK-sign when driving abroad. If one drives both with a car and a caravan/trailer, both must bear the label. The sign shall be elliptical (oval) 175×115 mm, white background with black lettering. The letters must be 80 mm in height, the distance between them shall be 10 mm, and there shall be no advertising.^[10]

In 1971 Norway began with two letters and five digits, just after Denmark. In the beginning there was an informal system of avoiding the same code for a Norwegian and a Danish car, in which some letter combinations were used by Norway and some by Denmark. Norway having geographical codes used a higher number of letter combinations than Denmark. This was later abandoned, because of larger number of vehicles, so now a Norwegian and a Danish car can have same registration code, although they have national stripes now, and have always needed a national mark outside their country.
