The United Nations has its own postal administration, the United Nations Postal Administration (UNPA), which issues unique stamps and postal stationery. The UNPA was created in 1950, and the first stamps were issued in 1951. It has offices in New York, Geneva, and Vienna, and it’s the only postal authority in the world that issues stamps in three different currencies: US dollars, Swiss francs, and euros. These stamps are valid for postage only on mail sent from the respective UN offices. Their dual mandate is to generate revenue for the organization and to raise awareness about the UN’s work and global issues.
