Join the professional network that unites 124 countries and territories. If your professional organisation represents the majority of qualified architects licensed to practice in your country, and if it is not yet a member of the UIA, your organisation can apply for UIA membership. Contact the UIA General Secretariat by filling out the online form on this page. An application and questionnaire will be sent to you so we can learn more about your organisation. Your application will be submitted to the UIA Council for approval and once we receive the application fee and the first year's membership fees, your membership will become effective. New memberships are ratified at the following UIA General Assembly. As a UIA member, your organisation becomes a part of the UIA network. It benefits from the UIA's international visibility and global network. It can be represented on the UIA Council, organise a UIA World Congress of Architects and participate in international UIA-approved activities. You will receive regular information inviting your members to participate in UIA activities.
