The International Securities Identification Number (ISIN) 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 ticker symbols “which can vary by exchange and currency” for the same security.

ISO 6166 is the standard applicable to ISIN

The URI for a Code defined by ISO standards is defined in the RFC5141, by using the URL of ISO followed by the Code, as:
ISIN ->{ISIN code}
