The PPM is housed in its own building, which is next to the Panathenaic Kallimarmaro Stadium.
The Hellenic Post and the philatelic associations, in order to collect, preserve and exhibit historical objects that have been used since the founding of the Postal Service in Greece, created the PPM. Its foundation took legally place in 1966. In 1977, the housing building was donated to the State, by the philanthropist Nia Stratou for the Museum, which is being housed there ever since and started operating under the supervision of the Hellenic Post.
In 2013, the Philatelic & Postal Museum was transferred from the organizational structure of the Hellenic Post to the General Secretariat of Telecommunications and Posts. Thus the Philatelic and Postal Museum Service was established (law 4111/2013). The Museum is an organizational unit of the General Secretariat of Telecommunications and Posts of the Ministry of Digital Policy, Telecommunications and Information.
