ISO members

We are a network of national standards bodies. Our members are the foremost standards organizations in their countries and there is only one member per country. Each member represents ISO in its country. Individuals or companies cannot become ISO members. Please see the list below for information about the ISO member in your 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.

Find out more about ISO membership and benefits in the ISO Membership Manual (2.3MB). And, read more about how ISO supports developing countries in international standardization work.
