Credit Card Verification Tool
Welcome to the Credit Card Validator! You can use this tool to verify one or more credit or debit card numbers with multiple validation methods, including Luhn checksum verification and card scheme verification via the card's IIN. You can test the validator with
4242424242424242, or numbers from our fake credit card number generator.
How This Card Number Validator Works
This tool uses the Luhn algorithm, an error-checking algorithm supported by all major credit card numbers, to verify each card numbers' length and validity.
If you choose to validate card schema, we use our list of known IINs for each card schema (Visa, MasterCard, Amex, etc) to determine the card type.
You can validate an unlimited amount of card numbers by entering one per line in the validation box. Results are provided in CSV-compatible format.
