• Source: List of Member States of the International Hydrographic Organization

As of May 2024, the International Hydrographic Organization (IHO) comprised 100 Member States, two of which are suspended because of their lapsed annual financial contribution. The IHO identifies its representative member organisations as the respective national hydrographic office(s). These organisations may themselves be part of wider national maritime or other administrations covering a larger range of tasks – such as the national organisations for transport, maritime regulation, environment, defence or oceanography. For example, in Norway and New Zealand the hydrographic offices are sub-organisations of the country's national geodata organisation; in the UK and France, they are part of the Ministry of Defence; in Finland the hydrographic Office is part of the department of transport. The up to date list of IHO Member States, their representative organisations and contact details are maintained in the IHO Yearbook - available at www.iho.int
