A Member Committee is established in a territory by its Academy of Sciences or Research Council, or by a similar institution or association of institutions. At present, one or more Member Committees have been formed in the following regions: Argentina, Australia, Austria, Belgium, Brazil, Bulgaria, Canada, Chile, China CIE, China SRS, Czech rep., Denmark, Egypt, Finland, France, Germany, Greece, Hungary, India, Ireland, Israel, Italy, Japan, Malaysia, Netherlands, New Zealand, Norway, Peru, Poland, Portugal, Russia, Saudi Arabia, Serbia and Montenegro, Slovakia, South Africa, South Korea, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom and USA.

The Members of the Union are the Committees whose applications for membership have been adopted at an Ordinary General Assembly. A Member Committee is established in a territory by its Academy of Sciences or Research Council, or by a similar institution or association of institutions. The Union can admit to membership a Committee that, in any territory, develops an activity in radio science. Member Committees, within their respective territories, have the same objectives as the Union. They have complete freedom in matters relating to their internal organisation. Each Member Committee appoints a Representative to the Council (See Article 21) and one Official Member to each Commission (See Article 30). The same Official Member can represent a Committee on more than one Commission. Each Member Committee is free to choose the Category in which it will adhere to the Union. The number of units of contribution payable annually to the Union by a Member Committee and the number of votes allocated to it in meetings of the Council are determined by the Category chosen, and are as follows:

Category 1 2 3 4 5 5A 6
Number of votes 2 4 6 8 10 11 12
Number of units of contribution 1 2 4 8 16 24 32

The value of the unit of contribution is fixed by the Council. A Member Committee can transfer to a higher Category at the beginning of any financial year. A transfer to a lower Category can be made during an Ordinary General Assembly or during the three-month period after the end of an Assembly. The transfer takes effect from the beginning of the next financial year. Unless the Council decides otherwise, a Member Committee which has not paid its annual contribution for two years is considered to have resigned from the Union. The Committee may, however, apply for Associate Membership. A Member Committee can resign from the Union by giving notice in writing to the Secretary General. In the event of resignation, the Member Committee is liable to pay its annual contribution for the current year. A Member Committee that resigns from the Union, or that is considered as having resigned in accordance with Article 9, loses all rights to the assets of the Union and all voting rights. In the event of the dissolution of the Union, the Council decides on the disposal of the assets of the Union. The assets shall not be distributed among the Members.

Associate Membership is reserved, as an option, for a) Committees which are established in accordance with Articles 3, 4 and 5, but are not yet ready for full membership; and b) Committees which, being already Members of the Union, wish to transfer temporarily to Associate Membership for financial reasons. Every Associate Membership will be reviewed at each General Assembly. Associate Member Committees are admitted to the Union at an Ordinary General Assembly. Associate Member Committees are not required to pay an annual contribution to the Union. They have no voting rights in the Council and in the Commissions, and have no rights to the assets of the Union. Each Associate Member Committee appoints one observer to the Council, and one observer to each Commission. The same observer can represent his or her Committee on the Council and on more than one Commission.
