The Association of National Numbering Agencies
The Association of National Numbering Agencies (ANNA) is a global member association of National Numbering Agencies (NNAs), seeking to foster standardisation within the financial industry by upholding the International Organization for Standardization (ISO) principles, and by promoting International Securities Identification Numbers (ISIN), Financial Instrument Short Name (FISN), and Classification of Financial Instruments (CFI) codes for financial instruments.
International Securities Identification Number (ISIN) - ISO 6166
The ISIN is the core identifier of securities transactions and settlement.
Financial Instrument Short Name (FISN) - ISO 18774
The FISN standard incorporates the issuer short name and the abbreviated characteristics for the financial instrument.
Classification of Financial Instruments (CFI) - ISO 10962
For each ISIN, the CFI is a detailed description of the type of instrument.
Legal Entity Identifier (LEI) - ISO 17442
ANNA and GLEIF launched an initiative to link ISINs and LEIs to improve transparency of exposure by linking the issuer and issuance of securities.
