When it comes to banking systems and financial transactions, BSB numbers play a vital role in ensuring that funds are accurately directed to the right accounts. BSB numbers, also known as Bank-State-Branch numbers, are a unique set of six numbers that are assigned to each branch of a financial institution in Australia.

The Importance of BSB Numbers

BSB numbers are crucial in the banking system as they serve multiple purposes. Firstly, they enable the identification of the specific branch of the financial institution.

This is important because many financial institutions have multiple branches spread across different locations. By utilizing BSB numbers, both customers and financial institutions can easily recognize and differentiate between the various branches.

Secondly, BSB numbers are used to route funds to their intended destinations. Each BSB number corresponds to a specific branch’s physical location, making it easier for funds to be channeled accurately.

This is particularly important when it comes to electronic funds transfers, as BSB numbers act as a routing code to direct funds to the correct branch and account.

Identification and Routing of Funds

BSB numbers facilitate the identification and routing of funds by linking them to specific branches and accounts within financial institutions. They act as an essential piece of information required for any interbank or intra-bank transaction.

When initiating a transfer, customers are typically required to provide the BSB number along with the account number of the intended recipient. The BSB number identifies the branch where the account is held, while the account number specifies the specific account within that branch.

Once the BSB number and account number are provided, the financial institution’s systems utilize them to direct the funds accordingly. This involves verifying the BSB number against their internal records to ensure its accuracy.

Once verified, the funds are then routed to the specific branch using the BSB number as the location identifier. From there, the funds are further directed to the individual account using the corresponding account number.

Both the BSB number and account number are crucial in ensuring that funds reach the intended recipient without any errors or delays. Incorrect or incomplete information can lead to funds being misdirected, returned, or even lost.

Therefore, it is important for both senders and recipients to double-check and verify BSB numbers and account numbers before initiating a transfer.

Advancements in Technology

With the advancement of technology, the use of BSB numbers has become more automated and efficient. Financial institutions’ systems are now equipped with algorithms and databases that can verify and validate BSB numbers in real-time.

This minimizes the risk of errors and ensures that funds are accurately routed. Additionally, online banking platforms and mobile apps have made it easier for customers to access and provide BSB numbers when making transfers.

These platforms often have built-in features that can match BSB numbers to the corresponding branches, further reducing the chance of errors.


BSB numbers are a fundamental part of the banking system in Australia. They play a crucial role in identifying specific branches and routing funds accurately.

By utilizing BSB numbers, both customers and financial institutions can ensure that transactions are processed efficiently and without errors. It is essential for banking customers to understand the importance of BSB numbers and to provide accurate information to avoid any complications or delays in their financial transactions.

Topic 3: PEH System_x000D_


The PEH system is an integral part of the Australian banking system, closely related to the BSB number. PEH stands for Processing Electronic House, and it refers to the electronic clearing system used for processing electronic funds transfers (EFT) between financial institutions in Australia.

This system allows for the smooth and efficient transfer of funds, ensuring that transactions are completed accurately and securely. The PEH system operates behind the scenes, working in conjunction with the BSB numbers to facilitate the transfer of funds.

When a customer initiates an electronic funds transfer, the PEH system processes the transaction by utilizing the BSB numbers associated with the sender and recipient’s accounts. Once the funds are successfully debited from the sender’s account, the PEH system relies on the BSB numbers to route the funds to the specific financial institution and branch where the recipient’s account is held.

The BSB number acts as a crucial identifier and routing code, ensuring that the funds are directed to the correct location. Throughout the process, the PEH system guarantees the security and integrity of the transaction.

It ensures that the funds are transferred accurately and promptly, minimizing the risk of errors or delays. Topic 4: Understanding BSB number structure

BSB numbers are structured in a specific format that provides valuable information about the financial institution, branch, and location associated with the number.

Each BSB number consists of six digits, and each digit carries its own significance. The first two digits of a BSB number represent the financial institution.

In the case of BSB number 402-561, the “40” indicates that the financial institution is the Commonwealth Bank. The Commonwealth Bank is one of the largest and most prominent banks in Australia, providing a wide range of financial services to individuals and businesses.

The third digit signifies the state or territory where the branch is located. In this instance, the “2” indicates that the branch is located in New South Wales (NSW).

New South Wales is the most populous state in Australia, and it is home to numerous thriving cities and towns. The following three digits, in this case, “561,” represent the specific branch within the chosen financial institution and state.

These digits differentiate the branch from other branches within the same financial institution and state. The branch represented by these three digits is located at 107 Dangar Street in the city of Armidale, with a postcode of 2350.

Armidale is a vibrant regional city in New South Wales, known for its educational institutions and natural beauty. By breaking down and interpreting the BSB number 402-561, we can determine that it belongs to the Commonwealth Bank, specifically to their branch at 107 Dangar Street in Armidale, NSW.

Understanding the structure of BSB numbers is crucial for accurate and efficient fund transfers. Customers must provide the correct BSB number to ensure that their funds are routed to the intended recipient’s account.

Financial institutions rely on the BSB number to identify the correct branch and location for processing the transaction.


The PEH system, along with the BSB number, plays a significant role in the Australian banking system. The PEH system ensures the smooth and secure transfer of funds between financial institutions, while the BSB number serves as a vital identifier and routing code.

Understanding the structure and significance of BSB numbers is essential for accurate and efficient fund transfers. By providing accurate BSB numbers, customers can ensure that their funds reach the correct branch and account in a timely manner.
