Official index of cities and towns including postal codes and perimeter
Centralized data sets for private and administrative use
In Article 24 of the regulations governing geographic names (GeoNV), the Federal Office of Topography (swisstopo) is commissioned to establish, administer and publish the new official index of cities and towns including postal codes and perimeter. The data are stored centrally at swisstopo and correspond to TOPIC «PLZOrtschaften» (postal codes and localities) of the official cadastral survey.
In collaboration with the Swiss Post Office, the data were collected by the cantonal surveying authorities who are responsible for their maintenance and update.
The data set covers all of Switzerland and is available free of charge.
