1920 to 1998: Postal, telephone and telegraphy services – the PTT

Both operate in the field of communication, both are accountable to the Confederation: as far back as the second half of the 19th century, there is an expectation that bringing together the “sister” postal and telegraphy administrations (including the telephone from 1878) will save operational and administrative costs. A large number of telegraph offices, and later also telephone offices, are housed in post office buildings. Between 1920 and 1928, they are gradually merged to form the PTT – the postal, telephone and telegraphy administration.

The PTT in the 1960s

Developments in technology, the economy and society present a range of different challenges for Swiss Post and the telecommunications services (telegraphy service and telephony). From 1960 on, the organization is therefore divided into departments for post, telecommunications services and administrative functions (including general secretariat, finance department, etc.). PTT now stands for post, telephone and telegraphy. A joint PTT account remains in place, with telecommunications services covering the deficits in postal services, i.e. the services are cross-subsidized. Each post office is also a public intercom station in the telephone network and an acceptance point for telegrams. In the eyes of the Swiss public, however, the PTT and Swiss Post are practically synonymous: people use the name PTT when they mean Swiss Post.
