What Epsilon COREid is
Epsilon COREid is a paid identity resolution service designed to recognize and reach more than 200 million U.S. consumers. It connects demographic, transactional, and behavioral interactions across online and offline channels to one consumer identity. COREid uses verified name and address data, pseudonymized profiles, and AI to evaluate probabilistic matches through a hybrid matching approach that also supports household matching. The service can fill data gaps and reduce inaccurate or duplicate records. Epsilon lists display, video, connected TV, social, audio, and in-store engagement channels, while closed-loop attribution links exposure with verified sales and engagement data. Epsilon says data is pseudonymized before entering the digital ecosystem and that COREid does not rely on third-party cookies. It reports more than 17,000 PubLink integrations and a similar number of direct publisher relationships on CORE Private Exchange. Pricing is on request, and prospective customers are directed to contact Epsilon.
