EUROPA / CEPT

The Europa postage stamp (also known as Europa - CEPT until 1992) is an annual joint issue of stamps with a common design or theme by postal administrations of member countries of the European Communities (1956-1959), the European Conference of Postal and Telecommunications Administrations (CEPT) from 1960 to 1992, and the PostEurop Association since 1993. Europe is the central theme.

EUROPA stamps underlines cooperation in the posts domain, taking into account promotion of philately. They also build awareness of the common roots, culture and history of Europe and its common goals. As such, EUROPA stamp issues are among the most collected and most popular stamps in the world.

Since the first issue in 1956, EUROPA stamps have been a tangible symbol of Europe’s desire for closer integration and cooperation.
