Kreiskennzeichen

Kreiskennzeichen is the prefix on German vehicle registration plates that identifies the district or district-free city where a vehicle is registered. The code appears on the left side of the plate, next to the EU circle with the country code D, and serves as a geographic marker for registration authorities and law enforcement.

The prefix consists of one to three letters and denotes the administrative district (Kreis) or a kreisfreie Stadt. The remainder of the plate is a combination of letters and numbers that uniquely identifies the vehicle within that district. The specific letter combinations are allocated by the relevant registration authority and are listed and maintained centrally.

Kreiskennzeichen are issued by local Zulassungsstellen (registration offices) under oversight of the Kraftfahrt-Bundesamt (KBA). The central registry maintains the official list of valid codes, and changes to district borders or status are reflected in updates to the code list. When a vehicle changes registration to a different district, the plate typically receives the code of the new district.

Legal and regulatory basis for Kreiskennzeichen lies in the Straßenverkehrs-Zulassungs-Ordnung (StVZO) and related vehicle registration regulations. The system forms part of Germany’s broader practice of Kfz-Kennzeichen, which ties a vehicle to its place of registration and thus to local administrative responsibilities, tax obligations, and enforcement.

Historically, Germany standardized vehicle plates in the mid-20th century, with later reforms expanding available codes and accommodating municipal reorganizations. Today, hundreds of Kreiskennzeichen exist, reflecting the country’s administrative geography and its ongoing adjustments to district structure.
