The European Conference of Postal and Telecommunications Administrations - CEPT - was established in 1959 by 19 countries, which expanded to 26 during its first ten years. Original members were the monopoly-holding postal and telecommunications administrations. CEPT's activities included co-operation on commercial, operational, regulatory and technical standardisation issues. Today 48 countries are members of CEPT.
