International Securities Identification Number (ISIN)

Updated October 1, 2019

What is an International Securities Identification Number (ISIN)?

An international securities identification number (ISIN) is a universally accepted identifier exclusive to a particular issue of a security.

How Does an International Securities Identification Number (ISIN) Work?

Every legitimate market-traded security issued worldwide is identified with its own unique ISIN. The ISIN is granted by the National Number Agency of the country in which the security is issued.

Why Does an International Securities Identification Number (ISIN) Matter?

Since the ISIN is recognized internationally, it is an efficient tool for securities trading, since it helps differentiate securities issued from the same issuer.
