# UN809-10 - 2001 UN Postal Admin. 50th Anniversary
U.N. stamps were first issued in U.S. currency on United Nations Day, October 24, 1951. The U.N.P.A. is the only organization in the world that is not a country or a territory and yet is permitted to issue postage stamps. Further, it is the only entity to issue stamps in three currencies: U.S. dollars, Swiss francs, and Austrian shillings. The stamps generate revenue for the U.N. and provide information on U.N. achievements and activities. The stamps are valid for postage on mail from the U.N. offices in New York, Geneva, and Vienna.
