Postal codes in Switzerland and Liechtenstein

This page is a summary of the postal codes of Switzerland and Liechtenstein.

The countries use four-digit numeric post codes, sorted by geographical location (from north to south, following railways and post car routes).

Format of postal codes (PLZ)

The Swiss postal codes are assigned geographically, from west to east. They don't follow political divisions (cantons, districts), but they follow a routing allocation, following railways and post car routes. The postal code of big cities finish with 00, and it is not allocated if in the region there isn't 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 (Berne)
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 anymore.

Postal codes of Liechtenstein are included in the same structure, using the range from 9480 to 9499.

As special cases:

  • the Italian territory of Campione has the postal code 6911 for mail passing through Swiss post.
  • also located in Italy, the Swiss Post office in Domodossola has the code 3907.
  • the German territory of Büsingen has the postal code 8238 for mail passing through Swiss post.
