LexisNexis® uses a proprietary linking technology in conjunction with their own unique identifier, LexID®, to resolve, match, and manage information for U.S. consumer identities. This patented linking and clustering method is the mechanism behind many LexisNexis products that leverage authentication, verification, and other identity management capabilities.

  1. When LexisNexis acquires a new record, LexisNexis assigns their own unique identifier, LexID. LexID isn’t derived from personally identifiable information, such as a Social Security number.
  2. Records with intersecting data points are linked together by LexisNexis’s patented Scalable Automated Linking Technology and are then assigned the same LexID.
  3. Identity profiles are continuously updated to ingest new records. This dynamic process paints an extremely accurate picture that accounts for identity changes over time.


We have added the LexID to our Gen3 LexisNexis Services. LexID is an alphanumeric identifier that can be up to 15 bytes in length for the inquiry subject. If the LexID isn’t found for a consumer, then the element for LexID isn’t returned in the results.

You can choose to have this ID returned by having it activated in your LexisNexis account settings.


Having the largest database of linked public and proprietary information helps customers fight fraud, mitigate risk, and remain compliant.
