The International Securities Identification Number (ISIN) is a unique 12-digit code made of alphanumeric characters assigned to a security that is universally recognized. 

ISINs are used for numerous reasons including clearing and settlement.

While filing an ITR wherein you are reporting your trades, it is required by law to fill the ISIN Code to arrive at the correct amount of capital gains/loss.
