The International Amateur Radio Union (IARU) was formed in Paris in 1925 to represent the interest of amateur radio to the International Telecommunications Union (ITU). It is made up of national amateur radio societies throughout the world and is recognized as the official voice of the Amateur Service. It is administered by one of its members, the American Radio Relay League (ARRL), which also provides the president of IARU. The IARU attends the ITU Conferences and has "observer" status recognition. The IARU Constitution last amended in 1989, organizes the Union into three regional organizations that correspond to the three administrative regions of the ITU. Current IARU membership is 144 national societies.
