Credit Card Validator

Welcome! This tool uses the Luhn algorithm to check if a credit card number is valid. The Luhn algorithm helps identify if the credit card number is mathematically correct. A valid result means that the number passes these mathematical checks.

However, it does not guarantee that the card is in use, active, or capable of being charged. It merely ensures that the format is correct and that the number could theoretically be a real card number.

Please note that this validator is for educational purposes and should not be used as a definitive verification tool for financial transactions. Furthermore, rest assured that we do not collect or store any of the numbers entered in the validator.
