LEI (Legal Entity Identifier)

A Legal Entity Identifier (LEI) is a 20-character alphanumeric code that uniquely identifies legal entities participating in financial transactions worldwide. Mandated by financial regulators after the 2008 crisis, LEIs provide transparency by linking to registration data including legal name, headquarters address, registration authority, and parent company relationships. Financial investigators use LEI lookups to verify corporate identity and uncover ownership structures.
