ISIN

An International Securities Identification Number (ISIN) is a 12-digit alphanumeric code that uniquely identifies a specific security.

Currently, an ISIN can be assigned to most forms of securities including stocks, bonds, options, and futures, derivatives, commodities, and currencies.

These codes are allocated by a country's respective National Numbering Agency (NNA). Unlike ticker symbols, which identify stocks at the exchange level, ISINs provide universal recognition for securities. They serve various purposes, including facilitating clearing, reporting, and settlement of trades across global markets. These codes play a critical role in protecting against counterfeiting and forgery.

The ISIN is typically composed of a two-letter country code, a nine-character alphanumeric code unique to the security, and a single check digit at the end to ensure data integrity.

ISINs provide a standardized method for identifying securities, making it easier for investors to track and trade various financial instruments across different markets worldwide. By using ISINs, investors can quickly access key information about a security, such as its issuer, type, and country of origin.
