What is an ISIN?
An International Securities Identification Number (ISIN) is a 12-character alphanumeric code that uniquely identifies a specific security, such as a stock, bond, or derivative. The ISIN system is defined by ISO 6166 and is used worldwide to facilitate cross-border trading and settlement. Each ISIN consists of a two-letter country code, a nine-character alphanumeric national security identifier, and a single check digit. For example, US0378331005 is the ISIN for Apple Inc. Our free ISIN search tool lets you look up any ISIN to find the corresponding stock symbols, company names, and market capitalizations across all global exchanges.
