Official Swiss addresses updated weekly are available via interactive and programmatic (RESTful) access to users interested in matching addresses to geographic locations. A download is also available under data.geo.admin.ch. For the first time now: all official adresses of Switzerland are available for free! Commercial providers meanwhile only offer a freemium access, and are often not up to date.

Using the REST Service , it is easy to generate an Excel file to generate a map based on addresses -step by step explanation here. Furthermore, Open Official Addresses together with parcels based on OpenData-Surveying https://opendata.swiss/de/dataset/amtliche-vermessung-opendata and roadnames (amtliches-strassenverzeichnis) allows the construction of a free and official base map
