The Derivatives Service Bureau (DSB) was founded by the Association of National Numbering Agencies (ANNA) in 2015 and allocates the following identifiers for OTC derivatives: • Classification of Financial Instruments (CFI) (ISO 10962) ; • Unique Product Identifier (UPI) (ISO 4914) ; • International Securities Identification Numbers (ISINs) (ISO 6166) ; and • Financial Instrument Short Names (FISN) (ISO 18774) ; The ISIN, UPI, CFI and FISN are globally recognised and adopted ISO (International Organization for Standardization) standards for identifying, classifying and describing OTC derivatives. The identifiers are used in regulatory reporting. The DSB’s purpose is to bring greater transparency to, and integration within, the OTC derivatives market, enabling institutional investors to standardise data and providing national and trans-national regulators with higher quality data for their supervisory activities.
