Switzerland postal codes are made up of four numbers. They're assigned based on geography, from west to east, kind of following where railways and PostBus routes go. Unlike some other places, they don't follow political divisions like cantons or districts. Instead, they use a routing system.
The first number in the postal code shows which of the nine postal districts in Switzerland it belongs to. These districts are numbered from west to east. The second number shows the routing district within that postal district. Then, the last two numbers point out the exact place in that routing district. The nine postal districts are:
When Switzerland introduced the postal code system in 1964, it was a big deal for its postal service. The idea was to make sorting mail easier, so people didn't need to know every little detail about where everything is. Over time, the system changed to keep up with how things work and how much Switzerland has grown. For example, the third number in the postal code used to mean something about the route, but now it doesn't really matter much because things work differently with modern transportation.
The postal code system has really changed how mail gets sorted and delivered in Switzerland. It's made things much smoother and more reliable. With this system, a town can have more than one postal code, and one postal code might cover more than one town or even more than one canton. This flexibility helps because Switzerland's geography and politics can be pretty complicated.
Besides Switzerland, the postal code system also includes Liechtenstein and a German place called Büsingen am Hochrhein, both of which have their own Swiss postal codes. Before 2020, an Italian place called Campione d'Italia also used Swiss postal codes, but not anymore—now, they use Italian ones instead.
