Postal codes in Switzerland and Liechtenstein

The Swiss postal codes are assigned geographically, from west to east. They do not follow political divisions (cantons, districts), but they follow a routing allocation, following railways and PostBus routes. The postal code of big cities finish with 00, and it is not allocated if in the region there is not a big center. Switzerland is divided into nine postal districts, numbered from west to east. Each district is subdivided into postal areas. Each area contains a maximum of one hundred units. The postal codes are made up as follows: :3436 Zollbrück :3 = district (Bern) :34 = area (Burgdorf) :343 = route (Burgdorf - Langnau) :3436 = post office number (Zollbrück) Today, the third digit has no real meaning anymore. In the past, mail was assigned to fixed railway or truck routes, but modern logistics do not need this practice any more. Postal codes of Liechtenstein are included in the same structure, using the range from 9480 to 9499. ==Summary of postal codes==
