What is HIN (Holder Identification Number)?

A HIN number (Holder Identification Number) is a unique identifier assigned to an individual investor by the CHESS (Clearing House Electronic Subregister System). It is used to track ownership of shares and other securities in the Australian securities market.
When you open a trading account with a Chess-sponsored stockbroker, you will be assigned a HIN number. This number can be used to record your transactions and track your holdings on the CHESS subregistry.
