About CC Checker

This tool validates credit card numbers using the Luhn algorithm and checks basic formatting:

  • Luhn Check: Validates the card number checksum
  • Card Type Detection: Identifies Visa, Mastercard, Amex, etc.
  • Expiry Check: Verifies the card hasn't expired
  • CVV Check: Validates CVV length (3-4 digits)

Note: This only performs mathematical validation. It cannot check if a card is actually active or has funds.
