Commonwealth Bank has moved away from physical passbooks for day-to-day banking, reflecting the broader industry shift toward digital transaction records. If you still possess a legacy passbook account, it is important to understand that these accounts have largely been transitioned to electronic record-keeping systems to align with modern banking security and accessibility standards.

For those holding older accounts, the physical book no longer serves as the primary method for updating balances or recording transactions. Instead, account history is now available through digital channels, which provide a more comprehensive and secure view of your financial activity.

Steps to Transition to Digital Banking

If you are still using a physical book, you may want to link your account to NetBank to monitor your balance without visiting a branch.

  1. Ensure you have your customer number or existing account details ready.
  2. Visit a Commonwealth Bank branch with your physical passbook and a valid form of identification.
  3. Request that the staff member link your account to your digital banking profile.
  4. Once linked, log into the CommBank app or NetBank to view your transaction history.
  5. Confirm that your digital balance matches the last entry in your physical passbook.

Troubleshooting Common Issues

MFA / Login issues: If you cannot log into your account, it is often due to an outdated mobile number or email address on file. You will need to contact the bank's support line or visit a branch to verify your identity and update your contact details so you can receive the necessary verification codes.

App or browser errors: If the app displays an error when viewing your account, try clearing the cache or updating the application to the latest version via your app store. Should the error continue, check if the bank is performing scheduled maintenance on their digital platforms.

Locked account: Access can be restricted if there are security concerns or multiple failed login attempts. To resolve this, you will need to call the bank's security team or visit a branch with your ID to verify your identity and restore access to your funds.

Pro-Tip: Before heading to a branch to manage a legacy account, call ahead to verify if your specific account type requires a scheduled appointment. This can save you time and ensure that the staff member assisting you has the necessary access to legacy account records.

Frequently Asked Questions

Can I still use my physical passbook to make deposits at the branch?

While you may still bring your passbook to a branch as a reference for your account number, the teller will typically process your deposit using the digital system. The passbook itself is no longer the official record of your balance. If you need a formal record of your transactions, it is better to request a printed statement from the branch or download a transaction history report from NetBank.

What happens to the money in an old passbook account that hasn't been used in years?

If an account remains inactive for an extended period, it may be classified as unclaimed money. This is a standard process where banks are required to transfer inactive funds to the government to ensure their protection. You can check if you have any unclaimed funds by searching the official ASIC Moneysmart website; if you find a match, you can follow their process to claim the balance back to your active bank account.

How do I get a printed statement if I don't use online banking?

If you prefer paper records over digital access, you can request periodic paper statements through the mail. Keep in mind that some account types may charge a fee for this service, and it will arrive at the postal address registered on your account. To set this up, call the bank's general enquiry line or ask a staff member at any branch to update your statement preferences.
