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

How CORE ID® is different

Privacy comes first.

Epsilon has a trusted, 50+ year legacy exceeding consumer, client and regulatory expectations for privacy and data stewardship.

Unrivalled accuracy.

CORE ID is the only identity resolution solution that requires a complete name and address validated by transactions, ensuring marketers reach the right person with maximum precision and efficiency.

Seamlessly on and off-site.

Our single source of identity resolution enables consistent 1:1 conversations everywhere consumers interact with your brand, all while maintaining rigorous data separation and privacy protocols.

Lifelong connections.

By anchoring to the uniquely sturdy bedrock of our people-based CORE ID, you can be confident your ability to reach customers over time won’t drift away with third-party identifiers.
