What is a BIN / IIN?
A Bank Identification Number (BIN) — now formally called an Issuer Identification Number (IIN) — is the first 6 to 8 digits of any payment card. Those leading digits are not random: they tell the payment system which network the card belongs to (Visa, Mastercard, American Express, Discover, JCB, UnionPay and others), what type of card it is, and which bank in which country issued it. This lookup reads publicly documented BIN ranges only — it needs just the leading digits, never a full card number, expiry or CVV.
How to use this tool
- Type or paste the first 6 to 8 digits of the card number into the box above.
- Press Look up (or Enter).
- Read the scheme, card type, level, issuing bank and country in the result card.
- Use Copy result or Copy link to save or share what you found.
What each field means
- Scheme / Network — the card network that processes the card: Visa, Mastercard, Amex, Discover, and so on.
- Type — whether the card draws on a bank balance (debit), a credit line (credit) or preloaded funds (prepaid).
- Level / Brand — the product tier, such as Standard, Classic, Gold, Platinum, Business or World.
- Bank — the issuing bank, with its website and phone number when known.
- Country — where the issuing bank is based.
- Luhn — every real card scheme uses the Luhn checksum, so a well-formed number always passes it.
Who uses BIN lookups?
Developers testing checkout and payment flows, merchants running fraud and risk checks, finance teams doing reconciliation, and support staff confirming which bank issued a card. Because a BIN maps to a range of cards and a bank — not to a person or an account — it exposes no personal data. See our methodology for how the data is built.
