FAQ
Identity resolution allows you to stitch together user behavior across platforms, anonymous or known state and devices, which allows you to see the entirety of a user’s journey and combine their customer data into a single golden profile. It is essential for understanding customer needs and preferences, as well as creating personalized customer journeys - especially in light of the ongoing legal changes around third-party cookie tracking.
Unify resolves user identities in a deterministic manner. The Identity Graph supports multiple external IDs without any additional code. Each incoming event is analyzed, the external IDs are extracted, and then the Unify identity resolution tool algorithm matches events with profiles. A simplified version of the algorithm is as follows: Segment first searches the Identity Graph for incoming external IDs. If Segment doesn’t find a matching profile, a Profile is created for that user. If Segment finds one Profile, the event is logged onto that profile. If Segment finds multiple matching profiles, Segment applies the identity resolution settings to add the event to the appropriate profile.
Unify continuously ingests new data and automatically updates profiles in real time. As customers interact across channels, Unify reconciles identifiers (like email, device ID, or account number) so businesses always have the most up-to-date view.
Unify supports a wide range of identifiers including email, phone number, device ID, user ID, account ID, and custom traits. You can configure deterministic and probabilistic matching rules to stitch fragmented data into a single, trusted customer profile.
