Countries in the International Organization for Standardization

This article is about ISO member countries. For the ISO standard for countries, see ISO 3166-1.

There are, as of 2025, 174 members of the International Organization for Standardization. Three types of membership status can be distinguished:[1]

  • Full member (member body): sets the course for ISO standards development and strategy: participates and votes in ISO technical and policy meetings; sells and adopts ISO standards nationally.
  • Correspondent member: attends ISO technical and policy meetings as an observer; sells and adopts ISO standards nationally or within their membership territory.
  • Subscriber member: keeps up to date with ISO’s work, but cannot participate in it; do not sell or adopt ISO standards nationally.
