Questions, answered.
01Does this check if the card is real or has funds?
No, it only checks that the number is structurally valid (the Luhn checksum), the same first check a payment form does before contacting a bank.
02Is my card number sent anywhere?
No, the entire check runs locally in your browser. Nothing is transmitted or stored.
03Is Credit Card Validator free to use?
Yes, Credit Card Validator is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
