The purpose of international identification codes allocation is to provide standard identification of securities and other financial instruments within a single system and to disseminate this data among capital market participants.
ISIN (International Securities Identifying Number) code - is the recognized global standard for unique identification of financial instruments. ISIN code does not contain information characterizing financial instruments but rather serves to identify a security for trading and settlement purposes.
The ISIN code consists of 12 characters. The first two characters are taken up by the alpha-2 country code as issued in accordance with the international standard ISO 3166 of the country where the issuer of securities, other than debt securities, is legally registered or in which it has legal domicile. For debt securities, the relevant country is the one of the ISIN-allocating National Numbering Agency. According to ISO 3166, the country code given to securities issued in Azerbaijan is “AZ”. The next nine characters are taken up by the local numbering code of the security concerned. The final character is a check digit computed according to the modulus 10 “Double-Add-Double” formula.
International Organization for Standardization (ISO) 6166 currently defines an ISIN’s structure. ISIN can be attributed to most forms of securities, including equities, debt instruments, derivatives (options and futures) and other instruments (indexes, currencies, etc.)
The international standard ISO 6166 has been registered under AZS-267 at the State Agency on Standardization, Metrology and Patents of the Republic of Azerbaijan and has become legally binding in the territory of Azerbaijan. Moreover, allocation of ISIN codes in Azerbaijan is also regulated by the “Rules on allocation international identification codes for securities issued in the territory of Azerbaijan”.
CFI (Classification of Financial Instruments) - reflects characteristics that are defined when a financial instrument is issued and remain unchanged during its entire lifetime. The CFI consists of six alphabetical characters. The first character stands for the category of financial instruments, the second character for the group in the category, and the last four characters for the key attributes of the group.
ISO 10962 defines the structure and format for classification of financial instruments approved by the International Organization for Standardization.
FISN (Financial Instrument Short Name) – has been developed to provide a consistent and uniform approach to standardize short names and descriptions for financial instruments. The ISO 18774 standard incorporates the issuer short name and the abbreviated characteristics for the financial instrument. It has a maximum length of 35 alphanumeric characters including:
- an “/” as the delimiter between issuer name and instrument description;
- an issuer name with a maximum length of 15 alphanumeric characters;
- an instrument description with a maximum length of 19 alphanumeric characters.
