UIA Associations E-Mailings - 2026
The Union of International Associations (UIA) maintains a database on international civil society: international non-governmental organizations (NGOs) and inter-governmental organizations (IGOs).
The UIA’s databases Yearbook of International Organizations and International Congress Calendar are continuously updated and currently include descriptive profiles of over 78,500 international associations – including contact details, history, aims, and membership – and details on over 572,000 international meetings of these bodies, from 1850 to the present, and also far into the future.
Annually UIA contacts over 25,000 international associations directly in order to update its database. In 2026 UIA will be updating the database for the 64th edition of its Yearbook of International Organizations, which will be published in 2027. These mailings are a chance for your organization or company to reach out directly to these associations!
With a response rate of over 35%, you can be certain that you are being seen!
