RampID

Leading people-based identity solution within LiveRamp's platform, widely adopted across the open web as a cookieless addressability standard

RampID is LiveRamp's proprietary people-based identifier, formerly known as IdentityLink, that serves as the connective tissue for addressable advertising in a cookieless world. It creates a persistent, privacy-compliant pseudonymous identifier tied to real people rather than devices or browsers, enabling marketers to recognize and reach audiences consistently across channels including CTV, display, social, and mobile. As the core identity product within LiveRamp's Data Collaboration Platform, RampID allows brands, publishers, and data partners to match, activate, and measure audiences with high fidelity. It operates through a network of thousands of integrations across the advertising ecosystem, making it one of the most widely adopted identity solutions in the industry. RampID is designed to function in environments where third-party cookies are absent, positioning it as a future-proof alternative for addressability. RampID's significance in the AdTech ecosystem stems from LiveRamp's extensive data network and long-standing relationships with major publishers, DSPs, SSPs, and data providers. It competes directly with other identity solutions like The Trade Desk's Unified ID 2.0, Criteo's PAIR, and ID5, but benefits from LiveRamp's established enterprise customer base and deep publisher integrations. RampID underpins LiveRamp's broader data collaboration and clean room offerings, making it central to the company's revenue and strategic positioning.
