About ANNA
The Association of National Numbering Agencies (ANNA) is a global member association seeking to foster standardisation within the financial industry by upholding the International Organization for Standardization (ISO) principles and by promoting ISIN, FISN and CFI codes for financial instruments. This is achieved through ongoing, collaborative work with market participants, regulators and other standards bodies.

Under ANNA’s stewardship, the role of the ISIN in enabling global financial communications has been established worldwide. Founded in 1992 by 22 numbering agencies, today ANNA’s membership continues to grow, with more than 120 global members and partners allocating ISIN, FISN and CFI codes on behalf of their local jurisdictions. By putting in place rigorous governance around the development, allocation and sharing of ISIN, FISN and CFI codes, ANNA helps facilitate open, transparent markets diminishing barriers to access, while protecting the integrity of the standards. As a result, ISIN has become the recognised global standard for unique identification for all types of financial and referential instruments, helping to connect and protect global markets.

In addition, ANNA has established the Derivatives Service Bureau (DSB), a fully automated global numbering agency to meet the specific operational and regulatory requirements of the over-the-counter derivatives markets.
