Member state

A member state is a state that is a member of an international organization or of a federation or confederation.

The World Trade Organization (WTO) and the International Monetary Fund (IMF) include some members that are not sovereign states; thus, neither organization ever speaks of "member states"; the WTO has simply "members" (see WTO members), whereas the IMF calls its members "member countries".[1]

The oldest global member state based organization is the International Telecommunication Union, which joined the United Nations System as a Specialized Agency of the United Nations after the creation of the UN.
