The International Amateur Radio Union (IARU) is a federation of national associations of certified radio amateurs, representing over 150 countries and separate territories around the world.

The three IARU Regions are organised to broadly mirror the structure of the International Telecommunications Union (ITU) and its related regional telecommunications organisations. The Regions comprise:
- IARU Region 1: Europe, Africa, the Middle East and Northern Asia
- IARU Region 2: The Americas
- IARU Region 3: Asia-Pacific

The IARU represents the interests of the Amateur Radio Service worldwide to relevant international organisations, promoting the interests of amateur radio and seeking to protect and enhance its spectrum privileges.

Saudi Arabia and Seychelles Join IARU

The IARU member-societies have voted to admit the Saudi Amateur Radio Society (SARS) and Seychelles Amateur Radio Association (SARA) to membership.

SARS was founded on 25 June 2018 and is legally registered/recognized to represent the amateurs of Saudi Arabia. As of January 2019 there were 66 members out of a total of 479 licensed radio amateurs in the country. SARS maintains a website at arsr.sa/en/.

SARA was founded in December 2018 and was registered with the Seychelles government on 31 December. SARA has six members, two of whom are licensed. It is believed that there are four licensed amateurs in Seychelles, a number that SARA hopes to increase.

Saudi Arabia and Seychelles are located in ITU Region 1 which also corresponds to IARU Region 1. Their IARU membership became effective on 9 October 2019 upon completion of the voting procedure set out in the IARU Constitution.
