We are a network of national standards bodies. These national standards bodies make up the ISO membership and they represent ISO in their country.
There are three member categories. Each enjoys a different level of access and influence over the ISO system. This helps us to be inclusive while also recognizing the different needs and capacity of each national standards body. Countries with limited resources or without a fully developed national standards system can still observe and keep up to date with international standardization in ISO. Read more about how ISO supports developing countries in international standardization work.
- Full members (or member bodies) influence ISO standards development and strategy by participating and voting in ISO technical and policy meetings. Full members sell and adopt ISO International Standards nationally.
- Correspondent members observe the development of ISO standards and strategy by attending ISO technical and policy meetings as observers. Correspondent members can sell and adopt ISO International Standards nationally.
- Subscriber members keep up to date on ISO’s work but cannot participate in it. They do not sell or adopt ISO International Standards nationally.
