Founded in 2017, The Advertising ID Consortium was created to enable buyers and sellers of programmatic advertising an opportunity to leverage a two-part identity framework of unified cookies and people-based identifiers to create more relevant campaigns and improve user experiences. 

Currently, the Consortium membership includes supply-side and demand-side technology platforms who represent a large share of programmatic transactions in the open web. In 2018, the Consortium opened its membership to marketers and publishers to participate in shaping the Consortium's priorities.

The Consortium is an independent, non-profit entity governed by a nine-person Board of Directors, selected by its membership. The Consortium is an open and neutral entity with a mission to democratize identity for the advertising industry.
