With the foundation of the first two IPA sections "Suisse-Genève" and "Suisse Friborg" (later called regions) in 1955, the IPA section Switzerland was also founded. The official foundation took place on May 9, 1955.

At the international congress in Paris on 16. and 17. In September 1955, our section and the German section were added to the world's largest association of police officers. At this memorable meeting in Paris Switzerland was represented by our friends René Goebler, Andre Clerc, André Baumgartner and Marcel Loegan.

Since 1978 the IPA is represented throughout Switzerland and divided into 14 regions :: Genève, Friborg, Vaud, Neuchâtel-Jura-Jura bernois, Valais, Berne, Biel & surroundings, Zurich, Central Switzerland, Ticino, Solothurn, Eastern Switzerland, Beider Basel and Aargau.

The first members of the Principality of Liechtenstein Security Corps were accepted as “guests” in the Eastern Switzerland region.

In the 36. General Assembly with 56 voters unanimously adopted the name change from IPA Eastern Switzerland to IPA Eastern Switzerland and Principality of Liechtenstein.
