What Epsilon COREid is

Epsilon COREid is an identity resolution service designed to help organizations recognize and reach more than 200 million U.S. consumers. It brings together interactions from different channels and systems into a single consumer identity, connecting demographic, transactional and behavioral data across online and offline touchpoints. Its profiles are pseudonymized and can be enriched with Epsilon proprietary insights; linking records can also fill gaps and reduce inaccuracies and redundancies. COREid uses a hybrid matching approach, with AI used to identify and evaluate probabilistic matches, and it supports household matching. The data foundation includes verified name and address information, strengthened through publisher partnerships and continuous validation. COREid can support engagement across display, video, connected TV, social, audio and in-store channels. Its closed-loop attribution connects exposure with verified sales and engagement data. Epsilon says identities are pseudonymized before data enters the digital ecosystem and that the service does not rely on third-party cookies. The company reports more than 17,000 PubLink integrations and a similar number of direct publisher relationships on CORE Private Exchange. Epsilon was founded in 1969. Pricing is on request.
