Welcome to the homepage of PTSS, the Post and Telecommunications Surveillance Service. This website is aimed at Communication Service Providers (CSP), Law Enforcement Agencies (LEA) as well as the Federal Intelligence Service (FIS) for information, communication and exchange purposes.

Annual report PTSS 2018

This is the first annual report to be published by the PTS Service. The 45-page report offers a behind-the-scene glimpse of the workings of the PTS Service, with valuable background information on the different areas in which it operates. How is the PTS Service structured? What issues it is called on to deal with on a daily basis? What are the challenges it faces and what exactly does “criminal procedure surveillance of telecommunications” mean?

The report is available for download in English, French, German and Italian.



In 2018, the Swiss prosecution authorities and the FIS ordered roughly the same number of surveillance measures from the PTSS as the previous year. According to the figures and a comparison with the total number of offences committed, telecommunications surveillance is used in about 1.5% of all offences. The ratio is highest for felonies and misdemeanours constituting a public danger, felonies and misdemeanours against the administration of justice, and drug trafficking.



Persons required to cooperate can submit an application via the extranet in order to have their obligation status assessed by PTSS, for example to have their status changed to CSP with reduced surveillance obligations (Downgrade). Documentation supporting the application must also be submitted here. Furthermore, the persons required to cooperate can communicate changes to their details, for example the contact details of their LI-Officers, via the extranet.
