ISIN

International Securities Identification Number (ISO 6166)

What is ISIN

The International Securities Identification Number is a 12-character alphanumeric code defined by the ISO 6166 standard as a universal way of identification of financial instruments. 

ISINs are used to identify most types of financial instruments, including equity, debt, derivatives and indices. For more information about the different identifiers used for OTC derivatives, please read our paper on the framework.
