What is ISIN,How it work?

Unique code identifying a security for international transactions. Developed by International Standards Organization (ISO) and supported by the Group Of 30 (G-30) and many other nations, ISIN is a 12-digit (no letters) code comprising of the ISO country code, the local code number of the security (provided by the national numbering agency such as CUSIP in Canada and the US), and a checksum digit.
