Free BIN Checker
A BIN checker looks up a Bank Identification Number against an issuer database. Enter the first 6 to 8 digits of a payment card number to see issuing bank, card brand, card type, and country without exposing the cardholder.
BIN details appear here after a successful lookup.
Use this page to look up a BIN from a debit or credit card, then read issuer details. How a BIN (IIN) works, what a BIN lookup returns, when the tool is useful, and how the on-page form relates to a BIN lookup API follow in that order.
What is a BIN (Bank Identification Number)?
A BIN (Bank Identification Number) is the first 6 to 8 digits of a payment card number. Those digits identify the institution that issued the card: the issuing bank, the card network, and the country of issuance. BIN numbers sit at the start of a Visa, Mastercard, American Express, Discover, and similar card number. They are routing information, not a name, address, or CVV.
Payment processors already use the BIN behind the scenes to route an authorization. The form above brings the same issuer record to the screen so a merchant, fraud analyst, or cardholder can read it before a payment is processed.
BIN vs IIN
BIN vs IIN names the same digits. Bank Identification Number is the everyday payments phrase. Issuer Identification Number is the name in the ISO/IEC 7812 standard. A BIN lookup and an IIN lookup are the same job.
Is a BIN 6 or 8 digits?
A BIN is 6 or 8 digits. Six is the common lookup length. Eight is the current issuer range after Visa and Mastercard expanded BINs in April 2022. Enter the first six digits first. If the tool returns no match, enter eight digits. Do not paste the rest of the card number.
How the BIN checker works
The BIN checker works by matching the digits you enter to an updated issuer database, then returning bank, brand, type, and country. The tool does not call the issuing bank for an authorization and does not see whether the card has funds.
How to use the BIN checker
You should enter the first 6 digits of the card number into the BIN checker; if that lookup fails, enter 8 digits.
- Open the form at the top of this page.
- Type the BIN code with numbers only and no spaces.
- Choose Check BIN and wait for the issuer record.
- Read issuing bank, card brand, card type, and country. If the six-digit lookup is empty, retry with eight digits.
Never submit expiry, CVV, or the full card number to a BIN lookup. Those values are not required to identify the issuer, and they are not public routing data.
What a BIN lookup returns
A BIN lookup returns issuer metadata for the digits you entered: bank name, network, funding type, and country of issuance. The fields a BIN lookup returns are listed below.
| Field | What it means |
|---|---|
| BIN / IIN | The 6 or 8 digits you looked up |
| Issuing bank | The financial institution that issued the card (bank name) |
| Card brand / network | Visa, Mastercard, American Express, Discover, and similar |
| Card type | Credit, debit, or prepaid (how the card draws funds) |
| Country | Country of the issuing institution, often with ISO codes |
Some tools add bank phone, website, currency, commercial flags, or prepaid flags. Those extras are still issuer facts. They are not cardholder personal information.
Issuing bank, card brand, and card type
The issuing bank field names the financial institution that issued the debit or credit card; the brand and card type sit beside it. Merchants use that trio to price, route, and risk-score a payment.
Country and other issuer fields
Country in a BIN lookup is the country of the issuing institution, often with ISO A2 / A3 codes, not the cardholder’s shipping address. A mismatch between BIN country and IP or billing country is a fraud clue, not a completed investigation.
Issuer metadata before you process
A free BIN checker is useful when a merchant or payment team needs issuer context before processing a payment without storing a full card number.
Check a BINBIN checker FAQ
How do I know which digits are the BIN code in the CC number?
The BIN code is the first six digits of a typical 16-digit debit or credit card number; on some 18- or 19-digit products the issuer range is eight digits. Start with six in the form. If you get an error, enter eight. Stop there.
Why does the BIN checker show no details?
The BIN checker shows no details when the digits are mistyped, when the range is missing from the updated database, or when you entered fewer than six numbers. A blank result is not a verdict that the card is fake; it is a miss in the lookup table.
Can a BIN code change over time?
A BIN code can change over time after a bank acquisition, a rebrand, or a network reassignment, but it usually stays consistent for an institution.
Can a BIN identify a cardholder’s personal information?
A BIN cannot identify a cardholder’s personal information. It details the issuing institution, card type, country, and related issuer flags. It does not return a name, national ID, or the rest of the card number.
Does a BIN checker prove a card is valid?
A BIN checker does not prove a card is valid. It returns issuer metadata and, at most, a format check. Only an authorization from the issuing bank can confirm a specific account.
