The Union is governed by its General Assembly, which meets every three years. The Council is its top executive body, supervising the activities of the nineteen specialized International Commissions and the three Affiliated Commissions. The Union is composed of Members representing identified physics communities. At present 49 Members adhere to IUPAP.
