Until the year 2000, the ISIN code data was distributed using disks till transmission via the internet. In the year 2004, the ISIN code became extremely important when the European Union (EU) mandated the use of the system for significant regulatory reporting needs. However, it wasn’t widely used until the Group of 30 (G30) nations called for all their members to adopt the numbering system in 1989 to distinguish between various investment tools. A year later, the International Organisation for Standardisation (ISO) joined the Group and started using the ISO 6166 standard as its reference.
- ISINs were first used in 1981, but did not reach wide acceptance until 1989, when the G30 countries recommended adoption.[1] The ISIN was endorsed a year later by ISO with the ISO 6166 standard.
- For example, according to ISIN Organization, IBM common stock is traded on close to 25 trading exchanges and platforms, and its stock has a different ticker symbol depending on where it is traded.
- Over time, most countries appear willing to adopt ISIN numbering either as a primary or secondary identifier to administer ISINs.
- To that end, they have worked out an information exchange process named GIAM-2, which uses the Internet and CD-ROM technologies.
The middle nine-digit grouping of the ISIN system number is administered by the local country’s numbering agency, which is CUSIP Global Services in the United States.

What’s the Difference Between ISIN and CUSIP?
In 1994, the Global ISIN Access Mechanism was created to electronically exchange ISIN information across regions through a digital information exchange process called GIAM-2. Universal acceptance of ISIN allows global straight-through processing (GSTP), which is the electronic handling of trade clearing and settlement. ISINs are used to track the holdings of institutional investors in a format that is consistent across markets worldwide. You can find the ISIN number for U.S. securities listed on the stock certificate or the prospectus for the shares in question. The relevant National Numbering Agency (NNA) in each country issues ISINs.
The ISIN standard is used worldwide to identify specific securities such as bonds, stocks (common and preferred), futures, warrant, rights, trusts, commercial paper and options. ISINs are assigned to securities to facilitate unambiguous clearing and settlement procedures. They are composed of a 12-digit alphanumeric code and act to unify different what is isin code ticker symbols “which can vary by exchange and currency” for the same security. An ISIN is often confused with a ticker symbol, which identifies the stock at the exchange level. For example, according to ISIN Organization, IBM common stock is traded on close to 25 trading exchanges and platforms, and its stock has a different ticker symbol depending on where it is traded. The ISIN code is the only common securities identification number that is universally recognized.
International Securities Identification Number or ISINs are a unique set of alphanumeric characters that identify a security being traded on the market. Where a ticker symbol shows the trading status of a stock based on the location it is being traded in, ISIN is specifically unique to the company universally. The ISIN number is administered by the corresponding National Numbering Agency present in the respective country. The first two are assigned by the country of origin and by the head office of the issuing company respectively. The 9 characters between the first and the last, are utilized for unique identification of the security. The last digit acts as a check digit to prevent errors and ensure authenticity of the code.

Understanding the ISIN Numbering System
International Securities Identification Number (ISIN) codes are 12-digit alphanumeric identifiers which are assigned to all types of securities. In each country, there is a National Numbering Agency (NNA) which issues and maintains ISIN allotments to securities based on the International Organization for Standardization (ISO) guidelines. ISINs were once considered only a secondary form of security identification, used exclusively for clearing and settlement. In recent years, some European countries have adopted ISINs as their primary security identifier. An offering memorandum or an prospectus is often required to obtain an ISIN.
Some protocols require the transmission of additional check digits added to the full ISIN number. The technical term for the check digit is the ten’s complement of the sum modulo 10. In English, this means the resulting sum, including the check digit, is a multiple of 10. ISINS are used by share custodians to track holdings of institutional investors in a format which is consistent across markets worldwide. In India, issuing ISIN for various securities has been assigned to the National Securities Depository Limited (NSDL) by the Securities and Exchange Board of India (SEBI).
The Luhn algorithm can also be applied in the same manner for both types or lengths (alternating multiply the string of digits by 1 and 2, starting from the end of the string), being more generic. The middle nine digits of ISIN numbers are computer-generated in a complex algorithmic formula. This numbering process is critical in helping to protect against counterfeiting, fraud, and forgery. This office emerged from the CUSIP Service Bureau, which was created in 1968 to improve the numbering system for securities by developing a national standard for the financial industry. It continues to enforce the numbering system through a board of trustees.
The National Numbering Agency in every country is responsible for issuing the ISIN for a specific country. Securities like quities, debt instruments like bonds and debentures, derivatives, commodities and currencies have an ISIN of their own. The reason why a stock can be said as a fungible security is because of its ISIN. An ISIN should not be confused with a ticker symbol, which identifies stock at the exchange level. A company’s security could have more than one ticker symbol depending on the trading platform, but the security will have only one ISIN. Another number set, usually, a Market Identifier Code (MIC) or three-letter exchange code, is needed to record location information that supplements primary identification codes.
For the government securities, the allotment of the ISIN code is regulated by the Reserve Bank of India (RBI). The NSDL was established in August 1996, under the aegis of the Depositories Act, 1996. International Securities Identification Number (ISIN) is an essential system implemented to identify a specific securities issue. So the ISIN check digit is still three even though two letters have been transposed. Take the 10s modulus of the result (this final step is important in the instance where the modulus of the sum is 0, as the resulting check digit would be 10).
The ISIN Organization provides management services related to International Securities Identification Numbers (ISIN). ISINs uniquely identify a security — its structure is defined in ISO 6166. Securities for which ISINs are issued include bonds, commercial paper, equities and warrants.
