LexID
LexisNexis employs an exclusive linking technology alongside its distinctive identifier, LexID®, to effectively resolve, match, and manage data for over 276 million consumer identities in the United States. This patented method of linking and clustering serves as the foundation for various LexisNexis products that utilize authentication, verification, and identity management features. Upon acquiring a new record, LexisNexis assigns it a unique LexID® that is not connected to personally identifiable information such as social security numbers. Records that share overlapping data points are interconnected through LexisNexis® patented Scalable Automated Linking Technology, leading to the assignment of a consistent LexID. The identity profiles undergo continuous updates to incorporate new records, ensuring that the information remains current. This ongoing process creates a remarkably precise representation that reflects changes in identity over time, thereby enhancing the reliability of the data.
