Welcome to the Association of National Numbering Agencies.
If you have invested in stocks, bonds or investment funds, you are already familiar with our work. We are the numbering agencies around the world that assign a unique identification code to each new security as it is issued.
Our proudest achievement is the global adoption of a common standard for identifying securities, the ISIN (International Securities Identification Number) according to ISO Standard 6166. Securities from more than 120 nations are identified by ISINs. No matter where a security was first issued, its ISIN enables it to be recognized and traded between buyers and sellers virtually anywhere in the world.
ANNA is committed to the use of standard identifiers to make the financial world a more efficient, safer and more stable environment for investors and the financial institutions that serve them.
In an increasingly regulated financial world, identifiers are more important than ever.

The ISIN – a global standard
Where is the ISIN?
The ISIN is a true global success story. More than 120 countries are assigning ISINs now, either through their own numbering agencies or with the assistance of experienced ANNA members.
Originally envisioned as special-purpose identifier for cross-boarder trading, the ISIN was initially issued in tandem with the local securities identifier. Today, in most major markets, the logical efficiency of a single global standard has been recognized and the ISIN is the only instrument identifier issued by the numbering agencies.
Countries Issuing ISINs
The World of Identifiers
ISO standards for financial information create
a common language of machines-readable codes that support accuracy, efficiency and mutual trust among global markets.
Though the ISIN was the first standard global identifier and continues to be central to all capital markets operations, the family has grown as needs were identified. Today, the group of ISO-standard identifiers are a “common language” understood all over the world, embedded into processes and software, and required in regulatory reporting.
