Overview

An identity fabric for the open internet

Designed with the needs of modern marketers in mind, Unified ID 2.0 (UID2) provides holistic targeting and measurement for an internet that’s becoming more privacy-conscious.

  • Greater precision

  • More efficient advertising

  • Cross-device and cross-channel frequency management

  • Holistic targeting and measurement

Built to benefit the entire ecosystem

By converting email and phone number data into hashed, salted identifiers, 
UID2s can serve as a superior signal to cookies in myriad ways.

For publishers

UID2 can make advertising more relevant, which in turn can drive more revenue for premium content platforms.

For clean rooms and customer data platforms

Direct integration with UID2 allows for seamless, privacy-conscious workflows and transfer of data for measurement.

For consumers

A universal UID2 opt-out function aims to provide a tool to control the user experience.

For data partners

Integrating with UID2 can create more durable audience segments for targeting and measurement.

How UID2 is different

Interoperable

UID2 works with other identity solutions across the open internet to maximize coverage of addressable audiences across all channels — including on Connected TV.

Portable

Since UID2 has been adopted by many leading ad tech providers and platforms, it’s easy for participants to use the identity strategies that work best for them, with the partners they choose.

Privacy-conscious

Data is hashed with a rotating salt and tokens are encrypted to obscure the source data used to create the UID2.

Omnichannel

Authentication is increasing across traditional digital, mobile apps, and especially Connected TV — enabling cross-device and cross-channel identity strategies without cookies.
