Credit Card Validator
Validate any credit card number using the Luhn algorithm. Instantly check card type, MII category, and issuer information.
What is Luhn Validation?
The Luhn algorithm (also known as the "modulus 10" algorithm) is a simple checksum formula used to validate credit card numbers. It detects accidental errors in card numbers, such as typos or single-digit mistakes. All legitimate credit card numbers pass this validation.
What is MII?
The Major Industry Identifier (MII) is the first digit of a credit card number. It identifies the industry category of the card issuer. For example, 4 and 5 are used by banking and financial institutions, while 3 is used by travel and entertainment companies.
What is IIN/BIN?
The Issuer Identification Number (IIN), also known as Bank Identification Number (BIN), consists of the first 6-8 digits of a card number. It identifies the institution that issued the card. Use our BIN Checker for detailed issuer information.
What is PAN?
The Primary Account Number (PAN) is the individual account identifier portion of a credit card number. It's located after the IIN/BIN and before the check digit. The PAN identifies the specific cardholder's account.
