Bank Identification Number lookup

The BIN Checker looks up the Bank Identification Number, which consists of the first 4 to 8 digits of a payment card. This prefix identifies the issuing bank, card brand, card type (debit or credit), and the country of issuance.

BIN lookups are commonly used by merchants to verify card details before processing transactions, by fraud prevention teams to flag suspicious activity, and by developers building payment systems. Knowing the issuing bank and country helps detect mismatches that could indicate fraudulent use.

Enter the first digits of a card number, and the tool returns whatever publicly available information is associated with that BIN. All lookups happen in your browser and no sensitive data is required since only the non-identifying prefix is used.

How to Use

  1. Enter the first 4 to 8 digits of a payment card (the BIN/IIN).
  2. The tool looks up the bank identification information associated with that prefix.
  3. View details such as the issuing bank, card brand, card type, and country.
  4. Use the information for verification, fraud prevention, or development testing.

What is a BIN?

BIN stands for Bank Identification Number. It is the first 4 to 8 digits of a payment card number and uniquely identifies the issuing bank and card type. The newer term IIN (Issuer Identification Number) is used interchangeably.

Is it safe to enter BIN digits?

BIN digits are the non-sensitive prefix of a card number. They identify the bank, not the cardholder or account. Sharing a BIN alone does not expose any personal financial information.
