What is Identity Resolution Software?
Identity resolution software helps organizations identify, match, and unify customer, user, or entity identities across multiple data sources, devices, channels, and interactions to create a single, persistent view of each individual. These platforms use deterministic and probabilistic matching, machine learning, and graph-based techniques to connect fragmented identity data from websites, mobile apps, CRM systems, offline records, advertising platforms, and other sources. The software often includes identity stitching, profile unification, householding, deduplication, consent management, and real-time identity enrichment to improve data accuracy and personalization. Many identity resolution solutions integrate with customer data platforms (CDPs), CRM systems, marketing automation platforms, data warehouses, and analytics tools to support omnichannel customer experiences. By creating accurate and persistent identity profiles, identity resolution software helps organizations improve marketing effectiveness, customer analytics, fraud detection, and privacy-compliant data management.

Before businesses can make use of their customer data, first they need to standardize their schemas, and then unify new and historical data. Even then, building on top of unified customer data in a single centralized system often requires dedicated development resources. Instead, unified customer data should be synced back to each department’s source system, making each system a distributed source of truth. Only then can businesses effectively manage risk, uncover fraud, and better serve their customers. Turn scattered and siloed customer data into a unified Customer 360 view.Starting Price: $2000/month -
