Check a card BIN format, Luhn validity and brand by prefix — no live BIN database, bank not identified.
Honest scope: there is no live BIN database in this tool, so it cannot identify the issuing bank. It reports format, brand-by-prefix and, for full numbers, the Luhn check only. Use test numbers only — never a real card number.
BIN result
How to use this tool
Just the BIN, or a full test number.
First 6 and first 8 digits, plus brand by prefix.
Shown only when 12 or more digits are entered.
That needs a live BIN database, which this tool deliberately does not claim.
Formula & worked example
411111 gives BIN 411111, brand Visa; a full test number 4111111111111111 also passes its Luhn check.
Limitations — read this before you rely on it
No live BIN database: the issuing bank, card level (credit/debit/prepaid), country and issuer cannot be identified here, and prefix ranges change over time as schemes issue new ranges. Full-number results are format checks only and prove nothing about a real card.
Frequently asked questions
The first 6 (or 8) digits of a card number, which identify the card scheme and, in a full database, the issuer.
There is no live BIN database in this tool. It reports format, brand-by-prefix and the Luhn check only — naming a bank would require a database lookup.
The scheme inferred from leading digits (for example 4 = Visa). Schemes issue new ranges over time, so this is approximate, not authoritative.
No — only that the digits are self-consistent. It proves nothing about existence, status or ownership.
No — use test numbers only, and never paste a real card number into any web page.
