United Nations Information Service (UNIS) Vienna

UNIS Vienna is part of a network of United Nations Information Centres spanning the globe, from Accra to Yaoundé, which are part of the Department of Global Communications (DGC). We share a common goal: to help fulfil the substantive purposes of the United Nations by communicating the activities and concerns of the Organization to the public.

UNIS Vienna plays a dual role: as UN Information Centre it serves four client countries - Austria, Hungary, Slovakia and Slovenia. By serving as the local voice of the UN in these countries, UNIS Vienna aims to promote an informed understanding of the work and goals of the United Nations, by reaching out to media, government, academia, schools and civil society organizations. UNIS also provides public information support and promotional services to the substantive programmes of the United Nations based in Vienna and acts as Secretariat to the United Nations Communications Group in Vienna.
