Bank Card Issuing Bank Lookup
- The issuing bank is identified by the card number prefix (BIN/IIN, typically 3–6 digits). This tool includes approximately 1,700 BIN rules covering more than 270 banks, using the longest matching prefix.
- The Luhn check is used to verify the structural validity of a card number. Some bank cards, such as certain China Merchants Bank American Express cards and some Bank of China debit cards, do not follow the Luhn algorithm. A failed check does not necessarily mean the card number is invalid.
- All processing is performed on this site. Card numbers are not uploaded or stored.
Lookup bank card BIN, card type, and issuing bank
Bank Card Issuing Bank Lookup
Enter a bank card number to identify basic information such as the issuing bank, card type, BIN, and card number length. The tool can also perform a basic structural check using the Luhn algorithm.
What is a BIN?
A BIN is the initial segment of a card number used to identify the issuing bank and certain basic card attributes.
What information can be checked?
- Issuing bank
- Card type
- BIN
- Card number length
- Basic Luhn validation result
Debit cards and credit cards
When the relevant information is available in the BIN database, the tool can identify debit, credit, quasi-credit, and prepaid card types.
What does Luhn validation mean?
The Luhn algorithm checks whether a card number follows certain mathematical structure rules. Passing the check does not prove that the card exists, is active, or can be used for transactions.
Card number length
Bank card numbers may contain between 12 and 23 digits depending on the bank and card product.
Issuing bank and account-opening branch
The bank identified by the BIN is the card issuer. It does not necessarily correspond to the specific branch where the account was opened.
BIN database updates
BIN information may change when banks launch new card products or adjust their numbering ranges. Unlisted BINs are reported accordingly.
Privacy and security
This tool does not provide the cardholder name, identity document number, balance, transaction history, password, SMS code, phone number, address, or other non-public financial information.
