ISIN to LEI Mapping Initiative

We are pleased to inform you that on 4 September 2018, the Association of National Numbering Agencies (ANNA) and GLEIF have announced the signing of a new initiative to link International Securities Identification Numbers (ISINs) and Legal Entity Identifiers (LEIs). It will improve transparency of exposure by linking the issuer and issuance of securities.

The new, global initiative will map new and legacy ISINs to their corresponding LEIs. By linking the two ISO standards together, firms will be able to aggregate the data required to gain a clear view of their securities exposure within a given issuer and its related entities. Once implemented, the ISIN-to-LEI mapping table will be made freely available to all without restriction on both the GLEIF and ANNA websites.
