The Official Munipality Key, formerly also known as the Official Municipality Characteristic Number or Municipality Code Number, is a number sequence for the identification of politically independent municipalities or municipality-free areas. Other names for the demarcation of such areas are ZIP Codes or postal codes.

Germany

In Germany the Official Municipality Key serves statistical purposes and is used by the Federal Statistics Office and/or by the statistics offices of individual German states. The municipality key is to be indicated in instances such as changing residence on the notice of departure or registration documents. This is done at the registration office in every town's city hall.

Structure

The municipality key consits of eight numbers, which are generated as follows: The first two numbers designate the individual German state. The third digit designates the government district (in areas without government districts a zero is used instead). The fourth and fifth digits designate the number of the urban area (in a a district-free city) or the district (in a city with districts). The sixth, seventh, and eighth digits indicate the municipality or the number of the municipality-free area.
