The Universal Postal Union (UPU, French: Union postale universelle) is a specialized agency of the United Nations that coordinates postal policies among member nations, in addition to the worldwide postal system. The UPU contains four bodies consisting of the Congress, the Council of Administration (CA), the Postal Operations Council (POC) and the International Bureau (IB). It also oversees two cooperatives including the Telematics and EMS Cooperatives respectively. Each member agrees to the same terms for conducting international postal duties. The UPU’s headquarters are located in Bern, Switzerland. The Universal Postal Union (UPU) was formed in 1874 and is the primary means of cooperation between postal services of all the nations of the world. This FDC with the block of 10c stamps with the postmark of UN, New York dated 22.3.1974 was issued to commemorate the 100th Aniversary of the UPU.
French is the official language of the UPU. English was added as a working language in 1994. The majority of the UPU's documents and publications – including its flagship magazine, Union Postale - are available in the United Nations' official languages.
