Accessing Your Account Number and BSB

To view your Commonwealth Bank account number and BSB, you can use the CommBank app or log in to NetBank. These digital platforms provide a secure way to access your financial details at any time without needing to refer to paper statements. Knowing where to find this information is helpful when you need to provide your details for salary deposits, bill payments, or transferring money between accounts.

Your BSB identifies the bank and the specific branch where your account is held, while your account number identifies your individual account. Both pieces of information are required for most domestic transfers within Australia. It is recommended that you retrieve these details directly from your official banking portal rather than relying on unofficial sources or old documentation that may be outdated.

Commonwealth Bank Current Account Length

Commonwealth Bank current accounts typically use a 14‑digit format, combining your 6‑digit BSB and your 8‑digit account number.

Breakdown of Digit Structure

Australian bank accounts require a 6‑digit BSB (Bank‑State‑Branch) and an account number. For CommBank, the account number part is usually 8 digits long, making a standard domestic format of six plus eight.

Mortgage and Credit Card Account Lengths

Mortgage account numbers at Commonwealth Bank are usually 9 digits long. Credit card account numbers are separate and consist of 16 digits.

Troubleshooting Common Issues

MFA / Login Issues

If you cannot access your account details because your security notification is not appearing, this is often caused by mobile network congestion. A simple fix is to toggle your phone's airplane mode to force a network refresh. The fallback action is to call the bank to verify your registered mobile number is current.

Browser or App Errors

Sometimes the portal might fail to load your account details. This usually happens when the application cache is cluttered or the app requires an update. Try clearing your app cache or updating the software through your app store. If the problem continues, log in via a desktop browser, which often provides a more stable experience.

Locked Account / ID Issues

If you enter your login details incorrectly multiple times, your access will be suspended for security. You cannot resolve this through self-service if your access is suspended. The fallback action is to call the bank's support team, as staff must manually verify your identity before they can restore your digital access.

Pro-Tip: Use the 'Share' or 'Copy' function in the app to provide your BSB and account number. This minimizes the risk of manual entry errors, which is a common cause of payment delays or funds being directed to the wrong account.

Frequently Asked Questions

What is the difference between my BSB and account number?

Your BSB identifies the bank and the specific branch, while your account number identifies your individual account within that bank. A real-world scenario is providing these details to an employer for your salary; if either number is incorrect, the payment will likely fail or be delayed. System logic requires both for every transfer. Your next step is to double-check these numbers against your official banking dashboard before sharing them.

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 "get" or claim; it is simply how the banking system processes fast domestic payments. It operates independently of your account number and BSB.
