United Nation postal administration

The United Nations postal administration (UNPA) is the official postal agency of the United Nations (UN) and the only postal authority authorised to issue stamps in the name of the UN. These stamps are issued in three different currencies: US dollars (New York), Swiss francs (Geneva), and Euros (Vienna) - and are valid only at the respective UN offices where they are issued.

Established in 1951, the UNPA produces postage stamps that highlight the work and values of the UN, including peace, human rights, environmental protection, and sustainable development. Through its postage stamps, the UNPA raises awareness of the UN's activities and achievements.

UNPA issued two Crypto stamps series, series 1 in 2020 and series 2 in 2022.
