    Achieve unrivaled accuracy and reach—without walls

    Effective marketing starts with knowing your customers—but walled gardens keep much of that knowledge hidden. That’s why Epsilon built a better way. COREID® services provide the industry’s most accurate, stable and scalable identity resolution solutions to recognize and reach 200M+ U.S. consumers in a privacy-safe way.

    Fill the gaps in your customer data with COREID solutions

    At Epsilon, we see data as little bits, bytes and blocks of all the actions that people take, online and offline. Watch how COREID services connect it all so you'll see each person fully, clearly and securely across all your marketing.

    Future-proofed ID resolution

    Epsilon saw the flaws of third-party cookies years ago. We designed our COREID solutions in 2007 with built-in privacy and have been strengthening our identity graph with direct publisher relationships since 2012. Because we designed with privacy in mind, we’re ready to adapt to any new legislation. This early and resilient approach is why our identity resolution platform has greater scale and accuracy than other solutions.
