Understanding the Card Replacement Process
Commonwealth Bank typically manages the replacement of expiring cards automatically. You generally do not need to request a new card; the bank will mail a replacement to the residential address linked to your account several weeks before the expiry date on your current card. It is important to ensure your address details are correct well in advance to avoid any disruption to your banking services.
Once you receive your new card, you will need to activate it before it can be used for purchases or ATM withdrawals. Because the new card will have a different expiry date and potentially a different card number, it is also important to remember to update any regular payments, such as utility bills or streaming subscriptions, that are linked to your previous card.

Card Replacement Timing and Next Steps
Commonwealth Bank typically sends your replacement debit or credit card 2 to 4 weeks before the expiration date printed on your current card. If you haven’t received your new card by the expiry date, contact CBA immediately on 13 2221. They can confirm mailing details, send a replacement or issue an emergency digital card.
Activation and PIN Setup
Once you receive your new CBA Debit Mastercard or Credit Mastercard, activate it before using. This can be done quickly via the CommBank app or NetBank: log in, navigate to the Cards section, tap Activate Card, enter the App PIN and the last four digits of your new card, then create or confirm a PIN. Activation is mandatory before using the card.
Update Recurring Payments
After activation, be sure to update your card details with any merchants or services that charge you automatically—since your card number and expiry have changed. Even digital wallets linked to your old card may continue to work via tokenization, but updating manually is recommended to avoid missed payments.
Troubleshooting Common Issues
MFA / Login Issues
If you cannot update your address because you aren't receiving your security notification (NetCode), this is often caused by mobile network congestion. A simple fix is to toggle your phone's airplane mode to force a connection refresh. The fallback action is to call the bank to verify your registered contact details.
Browser or App Errors
Sometimes the portal may fail to display your profile details correctly due to an outdated app version or a full browser cache. A simple fix is to clear your app cache or update the software through your app store. If the problem continues, try logging in via a desktop browser, which often provides a more stable interface.
Locked Account / ID Issues
Entering your login details incorrectly multiple times will trigger a security lock. You cannot resolve this through self-service if your access is suspended. The fallback action is to call the bank's support team or visit a branch, where staff must manually verify your identity before they can restore your digital access.
Pro-Tip: Update your address details at least one month before your card expires. This provides ample time for the bank to process the change and ensures your replacement card is directed to your correct location rather than an old address.
Frequently Asked Questions
What should I do if my card expires and I haven't received a replacement?
If you have not received your card by the time your current one expires, it may have been lost in the mail or sent to an incorrect address. A real-world scenario is the bank needing to confirm your current residency before dispatching the card. Your next step is to call the bank directly so they can check the status of your replacement card and organize a new one to be sent if necessary.
What is the CBA OSKO offer in Australia?
Osko is not an "offer," a promotion, or a service you need to sign up for. It is the brand name for the payment infrastructure (the New Payments Platform) that enables fast, near real-time transfers between Australian bank accounts, 24/7. It is standard technology integrated into your CommBank account. There is no Osko offer to claim—it is simply how the banking system processes fast domestic payments. It is unrelated to your physical credit or debit card, which functions independently of this payment rail.
