ANNA and GLEIF ISIN-to-LEI Mapping Service Jurisdiction Expansion

London, December 16th, 2020 – The Association of National Numbering Agencies (ANNA), a global member association seeking to foster standardisation within the financial industry by upholding the ISO principles and by promoting International Securities Identification Numbers (ISINs), Classification of Financial Instrument codes (CFIs), and Financial Instrument Short Names (FISN), for financial and referential instruments, announced today that additional jurisdictions have been added to the open-source relationship files provided through the certified ISIN-to-LEI mapping service. This certified initiative, which ANNA has undertaken with the Global Legal Entity Identifier Foundation (GLEIF), maps ISINs to their corresponding Legal Entity Identifiers (LEIs).

The collaboration between GLEIF, ANNA and the National Numbering Agencies (NNAs) was launched as a pilot project in April 2019. The aim of bringing these two ISO standards together is to improve transparency and aid risk and exposure management. Based upon a mapping process established by ANNA, the parties have worked to identify how existing workflows could be leveraged or modified for enhanced validation, resulting in GLEIF certification. Volumes of ISIN-to-LEI coverage have grown to 5.2m active ISINs linked to almost 72,000 unique LEIs.

22 NNAs have joined the ISIN-to-LEI Mapping initiative to date with ISIN coverage across 41 jurisdictions, most recently expanding to include Antigua and Barbuda, Bermuda, Bahamas, Belize, Cayman Islands, Curacao, EU, Grenada, Marshall Islands, Philippines, Puerto Rico, Saint Lucia, Saint Vincent and the Grenadines, Trinidad and Tobago and Virgin Islands (British), with more NNAs in the pipeline. Information on the participating NNAs is published on the ANNA website as and when they join the initiative.

The ISIN-to-LEI mapping table is freely available to all without restriction, and links to the data are available on both the GLEIF and ANNA websites.  The linking of ISINs and LEIs has also been endorsed by regulators, including the Financial Stability Board (FSB) and the European Securities and Markets Authority (ESMA). GLEIF certification was confirmed following final approval of the agreed operational expectations and revised cooperation Service Level Agreement, which incorporated GLEIF enabled LEI status exception reporting, at ANNA’s recent EGM on 19th November, 2020.

Dan Kuhnel, Chairman, ANNA, said, “We are delighted to see the initiative grow from strength to strength with NNAs joining on an ongoing basis. The partnership has exceeded initial expectations of purely mapping to incorporate new issues as it has also included mappings for existing active ISINs. It will continue to provide harmonised data standards to an increasing number of market participants.”

Stephan Wolf, CEO, GLEIF, said, “I’m excited that our partnership with ANNA is bringing ISO standards together and enabling data integration. Data quality has remained high with the number of third party challenges being very low. We know the partnership will only continue to strengthen and help the industry continue to find integration and seamless data alignment.”
