Identity Resolution: Answering the question of ‘who?’

Enabling businesses to identify and authentically connect with the people who matter most.

What is identity resolution?

Identity resolution analyzes billions of pieces of information using a powerful machine learning engine that ties together an individual’s separate online identities to create a single, accurate profile. If you have email addresses, social handles, phone numbers, or limited demographic data, FullContact turns your contact fragments into complete, enriched customer profiles.


Businesses can take advantage of identity resolution for more than individual engagement. Companies are building distinct competitive advantages by using it to derive insights and develop opportunities at an aggregated audience level.
