Organizations require clear, consistent identifiers to operate in the digital economy. However, multiple identifiers per legal entity can create ambiguity, inefficiency, and risk. GLEIF’s free, open-source LEI Mapping Certification addresses this challenge by allowing organizations to map their existing identifiers to the globally recognized Legal Entity Identifier (LEI). This process enhances transparency, interoperability, and trust while reducing data reconciliation costs and complexity.

Additionally, certified organizations benefit from publicly available mapping files that facilitate seamless integration and data comparison across systems and jurisdictions, establishing a standardized, trusted framework for global business identity.
