What is a BIN?
The BIN (Bank Identification Number), also called the IIN, is the first 6 to 8 digits of a card. It identifies the card network and the issuing bank, and tells you whether a card is credit or debit, consumer or commercial. Routing decisions, fraud rules and interchange all depend on it.
Why it matters for routing
If you run several gateways, the BIN is one of the strongest routing signals you have: a card issued in the US approves best on a US acquirer, a commercial card may carry different interchange, and some BIN ranges decline far more often on one processor than another. Unlimited reads the BIN on every transaction and sends it to the gateway most likely to approve it.
