What is a BIN

Every card carries a fingerprint. Read it in milliseconds.

A Bank Identification Number (BIN) — sometimes called an Issuer Identification Number (IIN) — is the first 6 to 8 digits of any credit, debit, prepaid or gift card. It tells the payment network which bank issued the card, what product it is, the card level, and the country of issuance.

BINs are assigned by card schemes like Visa, Mastercard, American Express, Discover and JCB, and are publicly attributable — they never identify a cardholder. Merchants, fraud teams and developers use BIN lookups to route transactions, prevent fraud, localize checkout and decide which card products they accept.

This tool resolves BINs in real time against public issuer registries. It is free to use, stores no cardholder data, and never sees full card numbers, expiry dates or CVVs — only the first 6 to 8 digits you enter.
