German Postal Codes
Contents
History
West Germany established a postal code system in 1962. These postal codes were 4 digits long (zero-padded). East Germany established a similar (but incompatible) system in 1965 (despite the West German system reserving codes for East Germany and provisioning a postal code to West Berlin).
Following German re-unification, the pre-existing postal code systems were used with a prefix of "W" (for West) or "O" (for East).
The modern postal code system in Germany was established in 1993.
The German-speaking nations have an informal (and decreasingly utilized) system of prefixing postal codes with a country code. Germany's code was "D", leading to postal codes like "D-12345". (Austria used "A", Switzerland used "CH", and Liechtenstein used "FL").
Specification
Modern German postal codes are 5 digits long (zero-padded).
Postal Codes by Region
The leading digit indicates a region. Note that these regions do not follow other political boundaries. Note also that Germany was divided into these regions with the intention of evenly splitting population, not area.
