Ever wondered why you need a Bank State Branch number (BSB) when you’re transferring money in Australia? Whether you’ve just moved to the country, are switching banks, or you’re managing everyday finances, BSB numbers are the key to making secure transfers. However, many people still get confused about where to find their BSB and when to use it.
Millions of Australians use these digits daily, without fully realising what their BSB number is, why it’s so important to them, and how it works. That’s why we’ve created this guide at Remitly to provide straightforward answers. We’ll cover what BSB numbers are, how to find them, when you need them, and how to use them safely for all your banking needs.
What is a BSB number?
A BSB number is a six-digit code that identifies a specific bank branch in Australia. It follows the XXX-XXX format, where the first two digits represent the bank, the third indicates the state, and the last three point to the individual branch.
For example, in the BSB number 062-000, “06” identifies the Commonwealth Bank of Australia, “2” represents New South Wales, and “000” specifies the exact branch. Each major bank has its own BSB number format, too; Commonwealth Bank BSBs usually—though not absolutely always—start with 06, Westpac with 03, and NAB with 08.
How do BSB numbers work in practice?
BSB numbers act like a postal code for your bank branch. Just as a postal code ensures a letter reaches not just the right street but the right building, a BSB number ensures money reaches the right bank account during transfers. Think of your account number as the apartment number, the BSB as the building, and the SWIFT code as the city.
So, for domestic payments, banks use a BSB with your account number to route funds quickly to the intended branch. However, when sending money Down Under from overseas, while the BSB still identifies the branch, you’ll probably still need the international SWIFT/BIC codes too.
Where to find your BSB number?
Finding your BSB number is simple once you know where to look, appearing on pretty much all of your banking documents, both paper and digital.
- Chequebooks: They’re quite rare these days, but if you’re still using cheques, your BSB number is printed on each one—usually near the top, alongside your account number.
- Bank statements: Your BSB number appears next to your account number on both paper and online bank statements. It’s one of the first details you’ll see when checking your account.
- Bank branch or customer service: If you can’t find it anywhere, you can visit a branch or call customer service to ask for your BSB number. They’ll need to verify your identity first.
- Online banking: When you log into your bank’s online portal, your BSB number will appear next to your account information. It’s usually under “account summary” or “details.”
- Bank websites and mobile apps: Most banks include a BSB finder on their websites or mobile apps. Just select your bank and branch to see the correct code.
You can find your BSB number in the most popular banking apps pretty easily, too. While these might change over time as newer versions of the apps come out, the BSB is so important that they’re never going to make them hard to find.
- Commonwealth Bank app: Open the app, go to accounts, select the account, and tap “account details.” You’ll see the BSB number next to your account number.
- ANZ app: Open the app, select the account, tap on “account details,” and your BSB will appear near the top.
- Westpac app: Log into the Westpac app, select your account, tap the share icon, choose a messaging app, and your BSB number will appear alongside your account details.
- NAB app: Log into the app, tap on account, then select account details to see both your BSB and account number.
When do you need your BSB number?
Now that you know how to find BSB numbers, let’s take a closer look at when you’ll need them.
Direct debits and recurring payments
You’ll need your BSB number to set up direct deposits for bills, such as electricity, water, internet, or subscriptions to stuff like Netflix. It ensures money is taken from the right account and paid to the correct provider, preventing failed payments or late fees.
Receiving salary or government payments
Your BSB number is required so your employer or government agencies like Centrelink can deposit your salary, pension, or benefits. It ensures payments go through smoothly without delays.
Transferring money between accounts
When transferring money between banks or sending it to someone else, the BSB identifies the receiving branch. This helps route transfers correctly and reduces the chance of errors.
Setting up automatic bill payments
Your BSB number is also essential to link your account for automatic payments such as your rent or mortgage, insurance payments, or loan repayments. Entering the right BSB number ensures payment goes through on time and avoids penalties or service interruptions.
International money transfers to Australia
You’ll also need your BSB number for international transfers into Australia. As we mentioned, you’ll still need the SWIFT/BIC numbers, but for incoming transfers your BSB number identifies the specific Australian branch. Without it, international transfers may not go through.
Opening or linking new bank accounts
When you open a new account or link accounts between banks, your BSB identifies which branch the account belongs to. It ensures transfers, deposits, and linked services all run without a hitch.
Verifying payments for business transactions
Businesses often ask for a BSB number when setting up supplier payments, processing invoices, or issuing refunds. Providing the correct BSB helps avoid delays or mix-ups.
Common BSB number mistakes to avoid
Even a small mistake with these Australian banking codes, like a single digit being wrong, can lead to rejected or misdirected payments. So watch out for these common mistakes:
Using incorrect or outdated BSB numbers
Entering incorrect or out-of-date BSB numbers—they do change from time to time—can cause failed payments or send money to the wrong branch. Be sure to confirm the current BSB with your bank before you make any transfers to avoid this. You don’t want an important bill payment to get missed just because the BSB was wrong.
Not updating BSB numbers after opening a new account
If you open a new account, even if it’s at the same bank as your existing accounts, it’ll have a different BSB if it’s at a different branch. So don’t forget to update your details for direct debits or salary deposits that you want to go to the new account. Let your employer, service providers, and any linked accounts know as soon as you switch.
Ignoring BSB changes during bank mergers or branch closures
We’ve mentioned that BSB numbers sometimes change. This is most common when banks merge or close branches. If this happens at your branch, or the branch of somebody you make regular payments to, it can trip you up. Stay in touch with your bank for the latest updates to ensure future payments continue without disruptions.
Confusing BSB with account numbers
An account number specifies your specific account, so mixing it up with your BSB can stop your payments from going through. Double-check that you’ve entered each number correctly in the right field before confirming any transfer.
Assuming one BSB applies to all accounts in the same bank
Different branches of the same bank have different BSB numbers, so always confirm you’ve got the correct one, linked to your specific bank or account.
Relying on third-party websites for BSB information
Some unofficial sites list outdated or incorrect BSB numbers. Use only your bank’s official website, app, or customer service for the most accurate information.
Using another person’s BSB by mistake
Copying someone else’s payment details by mistake, or reusing saved payee information without checking, can result in funds being sent to the wrong branch. Consider confirming the BSB directly with the recipient before transferring money.
Sending money from overseas to Australian accounts: step-by-step guidance
Sending money from overseas to an Australian bank account is simple once you know what details to include and how to check them. Here’s what to do:
Gather your account details
Before starting the transfer, ensure you have the recipient’s account and BSB numbers, along with their bank’s SWIFT code. Be sure to confirm these details through their bank’s official website.
Fill out the transfer fields accurately
When using online banking or an international money transfer service like Remitly, enter the exact account information. You may also need to include the bank’s full name and branch’s address.
Check for bank-specific requirements
Some international banks ask for extra information, such as an intermediary bank or a short description for the payment. Check with your bank or money transfer provider to ensure you include everything needed for a smooth transfer.
Understand processing times and fees
Domestic transfers within Australia are usually processed instantly, but international transfers can take between one and five business days, depending on the banks involved.
Some banks or transfer services may also charge fees, such as currency conversion costs and intermediary bank charges. Be sure to compare options and confirm all fees upfront to avoid unexpected costs.
Verify and track your transfer
After sending the money, keep your transaction reference number handy. Most banks and transfer services let you track your payment in real time. If there’s a delay or issue, your reference number will help resolve it faster.
Using your BSB number safely and effectively
BSB numbers are vital for ensuring your money goes to the right branch. As we’ve seen, they’re used for direct debits, salary deposits, and both local and international transfers—basically everything related to moving funds from one account to another. Entering the correct BSB keeps your payment accurate and on time.
As you would with any of your banking info, keep your BSB number secure and only share it with trusted sources. Keep it handy so it’s easy for you to find, and contact your bank if you’re ever unsure. That’s the best way to keep your banking safe and stress-free.
FAQs
Are BSB numbers the same as account numbers?
No. The BSB identifies the branch, while your account number represents your individual account. Both are required to ensure money reaches the right account.
Do I need a BSB number for international transfers?
Yes, when you’re receiving money from overseas into an Australian bank account, the BSB identifies the specific branch where the account is held. It works together with the SWIFT code to ensure funds are sent to the right place.
Can BSB numbers change?
They can. BSB numbers may change if your bank merges with another bank, closes any branches, or if you move your account to a new branch. Banks usually let customers know about any updates, but be sure to confirm your BSB before setting up new payments to avoid failed transactions.
Can I use the same BSB for multiple accounts?
Yes. Many banks use a single BSB number for several accounts at the same branch. However, each account has its own unique number, so the combination of your BSB and account number always identifies your account precisely.
Is it safe to share my BSB number?
Yes, providing you’re careful. It’s generally safe to share your BSB and account number when setting up legitimate transactions such as salary deposits or bill payments, but only with trusted parties.
