Vehicle registration plates (German: Kraftfahrzeug-Kennzeichen or, more colloquially, Nummernschilder) are mandatory alphanumeric plates used to display the registration mark of a vehicle registered in Germany. They have existed in the country since 1906, with the current system in use since 1956. German registration plates are alphanumeric plates in a standardised format, issued officially by the district authorities.[1][2]
All motorised vehicles participating in road traffic on public space, whether moving or stationary, have to bear the plates allotted to them, displayed at the appropriate spaces at the front and rear. Additionally, the official seals on the plates show their validity which can also be proven by the documentation coming with them. Motorcycles and trailers carry only a rear plate.
A significant feature of German vehicle registration plates is the area code, which can be used to tell the district of registration. It has developed into a widespread habit in Germany, even a children's game when travelling, to guess "where that vehicle is from".[3][4]
