With reduced reliance on the third-party cookie in the addressable advertising industry, European Unified ID (EUID) enables deterministic identity for advertising opportunities on the open internet in a privacy-conscious way. As an advertiser, you can join purchase and exposure data tied to EUIDs, thus optimizing audience targeting on the open internet in near-real time, while helping protect consumer privacy.

With the European Unified ID identity solution you can map user data to EUIDs, thus allowing EUID-enabled participants to use your first-party data to run more efficient advertising campaigns.

- Map email addresses, phone numbers, or their hashes to the corresponding EUIDs, previous EUIDs (if available) and refresh timestamps.
- Check when a EUID should be regenerated based on its corresponding refresh timestamp.
