The Derivatives Service Bureau (DSB)
The Derivatives Service Bureau (DSB) is a fully automated generator of International Securities Identification Numbers (ISINs) for OTC derivatives. Headquartered in London, the DSB is a legal subsidiary of the Association of National Numbering Agencies. Its core purpose is to serve as a global numbering agency, providing unique identification of OTC derivatives to serve the needs of market participants and regulators through allocation of the International Securities Identification Number (ISIN), as well as the Classification of Financial Instruments (CFI) and Financial Instrument Short Name (FISN), as OTC products are created. The ISIN, CFI and FISN are globally recognized and adopted ISO standards for identifying and classifying financial instruments. More detailed information on the DSB and its development path can be found in the DSB section and related pages, as well as recent announcements at the ANNA website, www.anna-web.org.
