"TR-1: Standard form for notification of major holdings 1. Issuer Details ISIN"

A 12-character International Securities Identification Number (ISIN) is a unique code that acts like a passport for a specific stock, bond or other tradable security so it can be identified worldwide. Investors and systems use it to ensure they are buying, selling and tracking the exact same instrument across exchanges and data feeds, which prevents costly mix-ups and makes portfolio reporting, settlement and regulatory checks simpler and more reliable.
