Share certificate number duplication should prompt a controlled comparison of the certificate log and underlying issue records. A repeated number may be a transcription error, an old cancelled certificate or another discrepancy. It does not, by itself, establish that shares were issued twice or that one holder’s document should be destroyed.

Preserve each version found

Keep copies of the documents and identify where the originals are held. Record the certificate number, holder, company, share class, quantity and apparent issue date. Avoid writing a replacement number onto a signed original while the facts remain uncertain.

Restrict access to signature material and shareholder information. Use a comparison schedule for the review rather than forwarding complete shareholder files to everyone who may recognise the number.

Trace the certificate history

Compare the log with approved allotments, transfers and any cancellation or replacement records. A log entry alone may not show whether a document was actually issued. Equally, an old scanned certificate may relate to holdings later transferred or consolidated.

Ask the secretary to identify the relevant underlying register and the evidence needed to reconcile the discrepancy. Do not infer current ownership solely from whichever certificate was found most recently.

Example: a cancelled certificate remains in a folder

A scan and the current log show the same number against different working references. The historical file indicates that one certificate was cancelled. Preserve the history and have the secretary confirm how the log should distinguish the documents. Deleting the older scan could remove the explanation.

Control any further issue

Flag the affected references so another administrator does not casually reuse them. Let the responsible secretary decide what correction or replacement process is appropriate after reviewing the actual documents. This practical control does not determine whether a certificate is legally effective.

Close with a reconciled index

Keep the accepted log, supporting corporate records and explanation together. Identify whether any originals, bank copies or shareholder communications need separate attention. ACRA’s company-record guidance is relevant context, but the immediate outcome is a traceable certificate history rather than an invented new share transaction.
