Understanding How Transactions Are Directed to the Correct Issuing Bank by Visa and MasterCard

Companies like Visa and MasterCard use advanced systems to ensure that transaction requests are directed to the correct issuing bank. This process is crucial for the smooth operation of financial transactions and the security of user data. Let's delve into how this works and what role the BIN (Bank Identification Number) plays in this process.

The Role of BIN in Transaction Routing

The Bank Identification Number (BIN) is a key element in the transaction routing process. It is the first six digits of a Visa or MasterCard credit card number. The BIN is assigned by Visa and MasterCard to specific issuing banks, allowing these financial institutions to be uniquely identified in the transaction process.

When a transaction is initiated, the transaction request is sent to the first few digits of the card number. These digits, known as the BIN, contain the identifying information of the issuing bank. As a result, the acquirer of the transaction (the merchant or service provider) can determine which issuing bank should handle the transaction based on the BIN.

The ISO Standard and Transaction Sensitivity

Over the years, the ISO standard for assigning BINs has become increasingly sensitive, allowing for more precise identification of issuing banks. This increased sensitivity has evolved from a four-digit standard to a six-digit standard and eventually an eight-digit standard. This evolution ensures that the system can handle a larger number of financial institutions and provide more granular control over transaction routing.

The transaction request from the acquirer will usually include the complete card number or at least the BIN. This information is used to forward the transaction request to the correct issuing bank for processing. This ensures that the transaction is handled by the appropriate institution, thereby maintaining security and avoiding fraud.

The Receiving Financial Institution

Once the transaction request is directed to the correct issuing bank, the transaction is further handled by the receiving financial institution. This institution, which is also known as the Receiving Financial Institution, plays a critical role in the transaction process. It is responsible for verifying the transaction details, ensuring that the transaction is legitimate, and processing the transaction accordingly.

The receiving financial institution is often identified by its ABA routing number, which is a unique alphanumeric code used in the United States to identify banks and other financial institutions participating in the U.S. clearing and settlement systems.

Authorization and Settlement Processes

Once the transaction is processed by the issuing bank, it is then forwarded to the receiving financial institution for final settlement. This process typically involves ACH (Automated Clearing House) or direct deposit transactions, as well as Fedwire transfers. ACH transactions are used for routine financial transactions, such as payroll and utility bill payments, while Fedwire transfers are used for high-value transactions.

After the transaction is settled, the financial institution that issued the card (the originating financial institution) will generate a statement and send it to the cardholder for reconciliation. In addition to digital statements, cardholders can also choose to receive paper statements or even pay their bills by cheque if preferred.

By utilizing the BIN and precise transaction routing, Visa and MasterCard ensure that every transaction is directed to the correct issuing and receiving financial institutions, maintaining the integrity and security of the financial system.

Conclusion

Understanding how transaction requests are directed to the correct issuing bank is essential for both financial institutions and consumers. The BIN, along with the ISO standard and transaction routing mechanisms, plays a pivotal role in this process. By utilizing these systems, Visa and MasterCard ensure that every transaction is handled securely and efficiently, benefiting both businesses and consumers.
