What Is an SRN? A Simple Guide for Australian Shareholders

If you have received a holding statement directly from a company or share registry, you may have seen a number beginning with the letter I. That number is usually your Securityholder Reference Number, commonly called an SRN. It helps identify an issuer-sponsored shareholding and is often needed when you update details, transfer shares or arrange a donation.

What does SRN mean?

SRN stands for Securityholder Reference Number. It is assigned to an issuer-sponsored holding. Under the issuer-sponsored system, the company's share registry maintains the record of your holding rather than a stockbroker sponsoring it through CHESS. An investor can therefore have a different SRN for each company in which they hold issuer-sponsored shares.

Where can I find my SRN?

Your SRN normally appears on an issuer-sponsored holding statement, dividend statement or other correspondence from the relevant share registry. It commonly begins with the letter I followed by numbers. Treat it like sensitive account information: do not publish it or send it through an unsecured channel.

Why is an SRN important?

The registry uses the SRN, together with your registered name and address, to locate and verify the holding. It may be requested when you register for online access, change communication preferences, transfer the shares to another holder, move the shares to a broker or donate them.

What if I cannot find it?

Start by identifying the company's share registry and contacting the registry directly. You may need to confirm your identity and the exact registered name and address attached to the holding. If the shares came from an estate, additional executor or probate documents may be required.

Can issuer-sponsored shares be donated?

In many cases, yes. Donate Your Shares Australia helps eligible shareholders complete an off-market transfer so shares can be transferred for charitable purposes. The exact requirements depend on the holding, registration details and supporting documents.
