Lost Your HIN or SRN? Find the Right Share Registry or Broker

An old dividend letter can tell you that a shareholding existed, but it may not tell you who administers it now. If you are trying to find lost shares and cannot locate your HIN or SRN, start by identifying the company and the organisation that holds the relevant records. Avoid guessing account numbers or sending the same identity documents to several unverified contacts.

This guide focuses on finding the right contact. For the broader search process, see our guide to finding lost shares and unclaimed money in Australia.

HIN and SRN: check which reference you are missing

A Holder Identification Number (HIN) relates to a CHESS-sponsored holding. ASX says it appears on a CHESS welcome letter and subsequent holding statements; your sponsoring broker can help retrieve it. A Securityholder Reference Number (SRN) relates to issuer-sponsored shares. Moneysmart explains that you have a different SRN for each listed company in which you hold issuer-sponsored shares.

Look for the name of the document as well as the reference. A dividend payment, an old purchase confirmation and a holding statement provide different clues. Do not assume one reference covers every investment. See Moneysmart’s explanation of SRNs.

Find the current registry for the company

ASX’s company directory lets you search by company name or code and find the share registry in the company details. Use the current company’s investor-relations page as another cross-check before contacting anyone. A registry name on a very old letter is a starting clue, not confirmation that the same organisation still manages the register.

If the name on your paperwork differs from the current listing, keep both names and the document date in your notes. Ask the verified registry which records it can search. Do not interpret a name change, an unfamiliar code or an unsuccessful login as proof that a holding has disappeared.

If you do not know your broker

Check the CHESS sponsor listed on an existing holding statement. If both your HIN and broker are unknown, ASX explains that the relevant share registry can help you request a CHESS PID, a reference that identifies the sponsoring broker. ASX Investor Support can then help identify that broker. Follow the current instructions in the ASX investor FAQs, rather than relying on an old contact number.

Prepare a short enquiry before sending documents

Keep the first enquiry focused on the missing information and the next verification step. You can prepare the following private checklist:

• The company name and any old name shown on the paperwork.
• The type and date of each document you found.
• Whether the paperwork mentions a CHESS sponsor or issuer-sponsored holding.
• The question you need answered: the correct registry, the sponsoring broker, or the process for replacing a statement.
• Any name or address mismatch you will need to explain once the recipient is verified.

Ask what evidence is required and how it should be submitted securely. Do not put a full HIN, SRN, identity document or account statement in a public comment. If you are acting for someone else, ask what authority the organisation needs before requesting account details. Requirements can vary with the holding and the person making the enquiry.

Keep the response useful for the next step

Create one enquiry note for each company. Record the date, the organisation contacted, how you verified its contact details, the reference it gave you and the specific follow-up requested. Keep a distinction between “records not yet checked”, “more evidence requested” and “no matching record found”. This makes it easier to explain what has already been tried without treating an incomplete search as a final answer.

For example, if you find two letters for different companies and only one includes an SRN, start two records. Resolving the first company’s reference does not resolve the second company’s history. This is an illustrative example, not a client case study.

When you need help organising the search

Investafind’s lost-share and investment tracing services describe its service scope. Before engaging any assistance, ask for the proposed work, fees and authority in writing. Knowing which registry or broker has already been contacted will make that discussion more specific.

This is general record-tracing information, not personal financial or legal advice. Finding an old reference does not establish a current balance, entitlement or recovery outcome. The responsible institution must verify the records and the person entitled to receive information.
