ID5 is the independent shared identity infrastructure for ad tech platforms and premium publishers. User IDs are key to the monetisation of audiences and inventory in programmatic advertising. ID5 matches user IDs between publishers, data providers and technology platforms – DSPs, DMPs and SSPs - to enable efficient and privacy-compliant transfer of user-level data. ID5’s technology increases monetisation capabilities and match rates between platforms.
