All these numbers? CSN, FIN, SRN, HIN

NZ Numbers
​
​CSN
CSN stands for Common Shareholder Number. We create and or apply an existing CSN for every account holder with us. This number will begin with a 3 and is nine digits long. You can find your CSN under My Preferences on the Invest Direct platform.
​
​FIN
Is effectively a pin code for your shares. Make sure you never share this with anyone and keep it in a safe place. It’s always sent in the physical mail to your registered address. If you have lost this number, you will need to contact your share's registry directly.
​
​Holder number
A holder number always starts with an R or N. These are unique to the holding and cannot be traded on, unless you want to sell the full balance. If you want to sell off a holder number, you can call us on 0800 805 777 to place the order over the phone. Alternatively, you can give us the holder number and FIN and we can merge it to the CSN we create for you. This way, you can sell them whenever you like.

​Australian numbers
​
​SRN
Stands for Shareholder Reference Number. In Australia, you can be issued holdings on SRNs and are used to identify 'issuer sponsored' shareholdings. SRNs do not consolidate and you will have a unique SRN for every separate company (and sometimes every transaction) on the ASX. We can buy and sell using these numbers, but it isn't the greatest customer experience as you need to wait for them to arrive in the mail, which takes 3-4 weeks from Australia. SRNs start with the letter 'I' and are generally 9-11 characters.
​
​HIN
A HIN number corresponds to a CHESS account with a broker. If you would like to open a CHESS account through us, please follow our trading on the ASX link here. CHESS or clearing house electronic subregister system, consolidates all of your ASX holdings onto one number and any transactions are instantly applied. This means, you can do very quick transactions on the ASX without any issue. Also, if you update your details, we manage that process for you. Once again, you manage your own dividends and corporate actions.
