I | / N N \ @ coning gt ISIN Issuer to LElI mapping table Factsheet GLEIF and ANNA 8/6/2021
/ N N \ @ P gk 1. Introduction
The Association of National Numbering Agencies (ANNA) is a global industry association promoting, implementing, and maintaining standards for financial and referential instruments. ANNA is committed to providing actionable global ID and reference data products and services to assist global market participants, including regulators and the financial services industry, to uniquely identify, classify and describe financial and referential instruments.
The membership of ANNA, National Numbering Agencies (NNAs), play a crucial role in the financial markets of their own nations, as well as global markets. Assigned and maintained by NNAs, the International Securities Identification Number (ISIN) ISO 6166, is the recognized global standard for unique identification of financial and referential instruments. Coverage includes, but is not limited to, equity, debt, derivatives, indices and digital assets.
The Global Legal Entity Identifier Foundation (GLEIF) is a not-for-profit organization created to support the implementation and use of the Legal Entity Identifier (LEI). GLEIF manages a network of partners, the Local Operating Units, to provide trusted services and open, reliable data for unique legal entity identification worldwide.
The Legal Entity Identifier (LEl) is a 20-digit, alpha-numeric code based on the ISO 17442 standard developed by ISO. It connects to key reference information that enables clear and unique identification of legal entities participating in financial transactions.
In this context, GLEIF and ANNA are publishing an ISIN-to-LEI mapping table, which will be updated on a daily basis and made publicly available.
The file is built upon a mapping process established by ANNA and certified by GLEIF. The purpose of this factsheet is to describe the reference data involved and the ongoing update process.
- Reference Data
The ANNA Service Bureau (ASB) is the consolidated source of global NNA data comprising the ISIN and associated reference data. Additional information on ASB data including field definitions can be found here.
The GLEIF Golden Copy File is the source for the LEls and the legal entity reference data. Additional information on the GLEIF Golden Copy Files and the Common Data File formats can be found here.
The ISIN-to-LEl mapping table only includes active ISINs where a LEI mapping is available from those NNAs who have joined the initiative. It does not contain ISINs that do not have correspondin
g LEls nor LEIs without corresponding ISINs. A full mapping table is produced on a daily basis i.e. is a “full” file, no listing of daily or monthly changes are provided.
Details of the NNAs who have joined the initiative are available on ANNA’s website, ISIN to LEI Mapping Initiative.
Additional ISIN data can be obtained via the free ANNA ISIN Lookup Service.

- File Specifications
The mapping table is published in comma-separated format (csv) on a daily basis. It contains all ISIN-LEI pairs, i.e. is a “full” file. No “delta” file is made available. The file does not contain ISINs that do not have corresponding LEls nor LEIs without corresponding ISINs.
