Common BINs for This Bank
If you have a card from this bank, you can use the BIN prefix to identify the card type and standard card number length. Click a BIN to fill in the corresponding card number segment.
Lookup Information
  • 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.

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.

What is a bank card issuing bank lookup?

The bank card issuing bank lookup identifies the issuing bank, card type, BIN, and card number length through the BIN segment at the beginning of the card number. It also performs a basic structural validation using the Luhn algorithm.
  • Identify the issuing bank through the card BIN range
  • Identify debit, credit, and other available card types
  • Display the BIN and corresponding card number length
  • Perform basic structural validation using the Luhn algorithm
  • Provide quick lookup access for common banks
  • Explicitly indicate unregistered BIN ranges
  • BIN lookup cannot retrieve the cardholder name, balance, transactions, or password
  • Account-opening branch, account status, and financial services should be confirmed with the issuing bank
This tool is primarily intended for basic identification of the card BIN, issuing bank, and card type. It does not provide cardholder personal information or account financial data. BINs may change as banks introduce new products or adjust numbering ranges, so results should be treated as reference information.
