In Germany, the Official Municipality Key is used for counting and data. It is given out by the statistics offices in each German state. You might see this key on important papers, like when you move to a new house.

How German Keys Are Structured

A German municipality key has eight numbers. Each part of the number tells you something different:

• The first two numbers show which German state the place is in.
• The third number tells you the government district. If there isn't a special government district, this number will be a zero.
• The fourth and fifth numbers show the number for a city area (if it's a city without smaller districts) or a larger district (if the city has smaller parts).
• The sixth, seventh, and eighth numbers point to the specific town or a special area that isn't part of a town.
