The International Organization for Standardization is a network of 171 national standards bodies.
ISO members are the foremost standards organizations in their country and there is only one member per country. Each member represents ISO in its country.
There are three member categories with different levels of access and influence. This helps us to be inclusive while also recognizing the different needs and capacity of each national standards body.
Full members (or member bodies)

This map is designed to visually demonstrate the geographic distribution of our Members. The boundaries shown do not imply an official endorsement or acceptance by ISO.
