ISIN

Definition:

International Securities Identification Number, the identification number unique to each issue of securities and generally used in European markets. An ISIN consists of three parts: a two letter country code (securities cleared through Clearstream or Euroclear use XS as the country code), a nine character alpha-numeric national security identifier, and a single check digit (used for error detection). Where a security has a CUSIP, the main body of the ISIN is the original CUSIP with US as the country code added to the front and an additional check digit at the end.
