How BIN lookup works
Enter the first digits
Every payment card starts with a 6–8 digit Bank Identification Number that encodes its issuer and network — no need for the full card number.
We match it against BIN data
Your input is matched against open BIN range data to resolve the issuing bank, card network, type and country of issue.
Get results instantly
Results appear in under a second, both on this page and via the same JSON API endpoint you can call from your own code.
Free Online BIN / IIN Checker & API
A Bank Identification Number (BIN), also called an Issuer Identification Number (IIN), is the first 6–8 digits of a payment card. It identifies the issuing bank, card network and country of issue — without revealing any cardholder information. Use this page interactively, or call the same free API directly from your own application.
Issuer Lookup
Identify the bank or financial institution behind a card, straight from its BIN — useful for merchants verifying incoming payments and reconciling transactions.
Network & Card Type
See the card network (Visa, Mastercard, RuPay, Amex and more) along with whether it's a debit, credit or prepaid card.
Country Detection
Instantly see which country a card was issued in — helpful context for fraud checks, risk scoring and regional payment routing.
Free JSON API
Every lookup on this page is backed by a public API endpoint you can call directly — no signup, no API key, and the URL is shown before you even run a search.
Privacy First
Only a BIN is required, never a full card number, CVV or expiry — nothing sensitive is ever collected or stored by this tool.
Open Data
BIN ranges are sourced from openly available, community-maintained databases, kept as current as possible for accurate, transparent lookups.
Frequently asked questions
A BIN (Bank Identification Number) or IIN (Issuer Identification Number) is the first 6 to 8 digits of a payment card number. It's assigned by card networks to identify the issuing institution, without revealing the individual cardholder's identity.
Yes — you only need the first 6–8 digits, which are shared by thousands of other cards from the same issuer and reveal nothing about a specific cardholder. Never enter a full card number, CVV or expiry date into any BIN checker.
Yes, the GET /api/bin/{cardNumber} endpoint shown on this page is free to call directly, with no signup or API key. Please keep request volume reasonable so the service stays fast for everyone.
Results are matched against openly available, community-maintained BIN/IIN range data. Coverage is broad but not exhaustive, and details like bank name or country can occasionally be outdated — always confirm anything payment-critical with your processor.
No. This is a lookup-only tool — it identifies information about an existing BIN you provide. It does not create or validate full card numbers.
