Adobe Visitor ID Service overview
The Adobe Visitor ID Service enables the common identification framework for CX Enterprise Application Services. You can use the Visitor ID Service to set the ECID.
The ECID is a shared identity namespace used across Adobe Experience Platform and CX Enterprise applications to track visitor behavior and ensure that each device has a unique identifier that can persist across multiple sessions.
The Visitor ID Service can replace different application-specific IDs and use the Customer IDs and Authentication States functionality to let you pass in your own customer IDs to CX Enterprise.
Visitor ID Service supports the following applications:
Going forward, the Visitor ID Service is an integral component of many current and future CX Enterprise features, enhancements, and services. Currently, the Visitor ID Service supports Analytics, Audience Manager, and Target. If you have not implemented the Visitor ID Service, now is the time to start considering a migration strategy.

Visitor ID Service requirements
Your solution and other Adobe code libraries must meet certain requirements before you can use the Visitor ID Service.
