Founded in 1977 as a specialised agency of the Organisation of African Unity, now African Union, in the field of telecommunications, the African Telecommunications Union (ATU-UAT) took its present name in 1999. This led to the transformation of the agency into a partnership between public and private stakeholders in the information and communication technology (ICT) sector.

ATU-UAT provides a forum for stakeholders involved in ICT to formulate effective policies and strategies aimed at improving access to information infrastructure and services. In addition, the Union represents the interests of its members at global decision-making conferences and promotes initiatives aimed at integrating regional markets, attracting investment into ICT infrastructure, and building institutional and human capacity.
