There are two types of IVV members: national association members and direct member clubs.
National association members consist of organized federations of clubs within a country. There can be only one IVV national association member per country.
Direct member clubs are individual clubs that exist in countries where there is no IVV national association member. There can be more than one direct member club within one country. It is hoped that if there are five or more direct member clubs within a country, they will join together to form a national association.
Applications and complete details on the criteria for membership are available from the IVV Office.
