# Merge User Profiles

One of Personalization’s key goals is to identify each of your customers with a Unified Customer Profile so that you can provide unique personalized experiences.

When identity data comes from different sources, Personalization uses specific identifiers to attempt to merge that data into a Unified Customer Profile. There’s no way to split a merged user profile.
