International Securities Identification Number, or ISIN, is a universally accepted number code identifier exclusive to a particular issue of a security, like a bond or stock.
Every legitimate market-traded security issued worldwide is identified with its own unique ISIN. The ISIN is granted by the National Number Agency of the country in which the security is issued.
Since the ISIN is recognized internationally, it is an efficient tool for securities trading, since it helps differentiate securities issued from the same issuer.
The International Securities Identification Number (ISO 6166:2001) is a system which allows precise identification of shares issued in one country but traded internationally.
