Official geographic directories

The official directories of localities, streets and building addresses in Switzerland are public and are available for use by everyone, free of charge. They are compiled, managed and published by the Federal Office of Topography swisstopo.

Official geographic directories

The Federal Office of Topography swisstopo produces the following official directories containing geographic data:

  • The official directory of towns and cities, with postcodes and perimeters
  • The official street directory
  • The official directory of building addresses.

These directories/datasets contain data that have been verified in terms of content and legality, and are updated on an ongoing basis. All federal, cantonal and municipal authorities can fully rely on the published data. The directories are free of charge and available to everyone: The data can be directly downloaded and are accessible via web services. The directories can be used for a broad variety of tasks: for example for statistical analyses and simulations with a geographic context, for use as a database for cartographic products, or for integration into a web service for commercial purposes.

Data protection

The directories are not linked to any personal data, i.e. data relating to natural persons and legal entities. They are therefore not governed by the provisions of the Federal Data Protection Act.

Datasets produced on the basis of partnerships

All the official directories are produced on the basis of partnerships. The data pertaining to localities, streets and buildings are collected by the cantons (and in some cases by the municipalities too), within the framework of the cadastral survey or other processes. The collected data are then delivered to the federal administration. Data pertaining to localities are delivered directly to swisstopo for updating the directory of towns and cities, while data relating to streets and building addresses are sent to the Federal Statistical Office (FSO) for statistical purposes. The FSO periodically supplies swisstopo with the respective datasets and swisstopo compiles and manages the directories and publishes them in a suitable form.

Legal bases for the official directories

The legal bases empowering the Federal Office Topography swisstopo to produce the official geographic directories and work together with the involved authorities have been in force since 1 July 2017:

  • The Federal Geoinformation Ordinance
  • The Federal Ordinance on Geographic Names
  • The Ordinance Governing Federal Buildings and Directories
  • The Ordinance of the Federal Department of Defence, Civil Protection and Sport on Fees and Charges of the Federal Office of Topography (swisstopo ordinance on fees and charges)

These ordinances are based on the Federal Geoinformation Act, which entered into force in October 2007.
