What is a Bank Identification Number (BIN)?

A Bank Identification Number, or BIN, is the first six digits of a card number that identifies the issuing bank, card network, and card type used in a payment transaction.

How BIN is Used in Card Payments

When a card transaction is initiated, the BIN helps route the transaction to the correct issuing bank. It also provides information about the card type, such as debit, credit, or prepaid, and the network such as Visa or RuPay. Payment systems use BIN data to validate transactions and apply relevant rules.

Why BIN Matters in Payments

BIN plays a key role in transaction routing, fraud detection, and payment processing efficiency. It helps identify the source of the card and enables better control over transaction approvals, risk checks, and settlement flows.
