Locating your account number is necessary when setting up direct debits, receiving salary payments, or providing details for a bank transfer. Commonwealth Bank provides several ways to access this information through their digital platforms, ensuring you can find your BSB and account number when required.

For security, these details are typically found within the authenticated environment of your banking portal. Whether you are using the mobile app or desktop banking, the information is usually clearly labeled alongside your account balance and transaction history.

Where to Find Your CommBank Account Number

  • Your account number is clearly shown on your banking statements, both paper and electronic.
  • Log in to NetBank online banking and navigate to the "View accounts" menu to see all linked accounts with their numbers.
  • Open the CommBank mobile app, go to "View accounts," and select the desired account to find the account number.

Troubleshooting common issues

MFA or login issues
If you cannot log in to your account, it may be due to a synchronization delay or an incorrect password. Try resetting your password using the "Forgot login" link on the NetBank page. If you are still blocked, call the bank to confirm your account status, as there might be a security hold on your profile.

Browser or app errors
If the app displays a blank screen instead of your account details, it is often due to an outdated app version or a poor internet connection. Update the app via your device's store or try using a different web browser on your computer. If the error remains, contact technical support for assistance.

Locked account or access issues
If your account has been locked due to multiple failed login attempts, you will not be able to view your details online. This is a standard security measure to protect your funds. You will need to contact Commonwealth Bank via phone or visit a local branch with identification to verify your identity and restore access.

Pro-Tip: You can download a digital "Proof of Account" letter directly from NetBank. This document is often accepted by employers or service providers and contains your BSB, account number, and bank details in a formal format, saving you from having to copy these numbers manually.

Frequently Asked Questions

Why does my account show a different number on my card?

The 16-digit number on your debit card is your card number, not your account number. The banking system uses these for different purposes; the card number is for processing payments via the card network, while your account number is used for direct deposits and transfers. If you provide your card number to an employer for salary payments, the transfer will not be successful. Your next step is to log into the app and retrieve the BSB and account number specifically listed under 'Account details'.

What should I do if my BSB is different from my account number?

The BSB (Bank State Branch) number is a 6-digit code that identifies your bank and the specific branch where the account was opened, while the account number is unique to your specific account. It is normal for these to be different. The banking system requires both pieces of information to ensure funds are routed to the correct destination. If you are ever unsure, check the official account details page in NetBank; it will explicitly label which set of digits is your BSB and which is your account number.
