The
Association of National Numbering Agencies (ANNA) announced 2 February 2023 for the National Numbering Agencies’ (NNAs) implementation of the revised ISO 6166 International Securities Identification Number (ISIN) standard, bringing further clarity and transparency in the identification and reporting of trades.
The revised ISO 6166 standard, which was published in February 2021, covers several items including an increased data set with the formal inclusion of legal entity identifier (LEI), classification of financial instruments (CFI) and financial instrument short name (FISN) as well as both financial and referential instruments.
In addition, it includes assignment rules for OTC derivatives.as already implemented by the Derivatives Service Bureau plus a clarification that ISIN is assigned on a technology agnostic basis, including assignment for tokenised financial and referential instruments.
Emission allowances, carbon credits and baskets confirmed as instruments are also on the list as is recognition that ANNA is responsible for determination of additional ISIN prefixes to ensure full coverage – for substitute numbering agencies
Upon implementation, the changes will be available to users of the freely available ISIN Lookup Service and subscribers of ASB services.
Emma Kalliomaki, managing director of ANNA, said, “ANNA has been working continuously with stakeholders to help address regulatory obligations as well as to address standardisation challenges. As the market evolves, so too has the ISIN standard under ISO’s governance.
She added, “Since the publication of the latest version of ISO 6166, there has been much discussion and collaboration on how best to set the implementation timelines, which are now agreed as February 2023.
The ISIN revisions have improved clarity of terms, scope and coverage of the standard, which further enhances usability, increasing transparency and aiding risk and exposure management thereby ultimately benefiting the market.”
