ISIN stands for International Securities Identification Number. It’s a unique 12-character alphanumeric code used across the world to identify securities like shares, bonds, and mutual funds. This system standardizes the way financial instruments are recognized by including existing national codes where applicable, ensuring uniformity everywhere.
ISINs make cross-border trading, clearing, and settlement much easier. They help keep global financial transactions efficient, transparent, and reliable for everyone involved—investors, brokers, and regulatory authorities.
