International Securities Identification Number (ISO 6166)
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.
The DSB is a single global provider of ISINs for OTC derivatives. For more information about ISINs, including those for other financial instruments outside of DSB OTC ISIN scope, please visit anna-web.org/identifiers/
