iValidCard

Check any credit or debit card number in seconds, and see exactly why it passes or fails. iValidCard works entirely offline: card numbers never leave your device.

VALIDATE
• Instantly detects the card network, from Visa, Mastercard and American Express to UnionPay, RuPay, Mir, Elo and more
• Shows the issuer, industry (MII), IIN, length and check digit
• Explains the Luhn checksum digit by digit
• Suggests the correct check digit when a number fails, and fixes it with one tap
• Scan a card with the camera, paste, or type

GENERATE

• Copy one or all, with or without spaces

HISTORY

iValidCard checks whether a number is well formed. It doesn't check whether an account exists or has funds, and it isn't affiliated with any card network or bank. Generated numbers are for testing only.
