Credit Card Validator

Instantly validate credit card numbers. 16 card types supported including VISA, Mastercard, American Express & Discover.

Valid Credit Card Number

We'll verify your number against the Luhn Algorithm to see if it is valid.

Major Industry Identifier

The MII is the first digit of a credit card number which represents the category of entity who issued the card.

Personal Account Number

The PAN is made up of the seventh digit on — everything except the last number on your card.

Multiple Card Types

Certain card issuers share the same Issuer Identification Number (IIN) - e.g Discover, Maestro and China Union all have an IIN starting with '62'. Therefore in some cases our validator will return multiple results.

Numbers are never stored, period.

Our credit card validator processes everything client-side within your browser. We do not send or store any credit card numbers. Without having address & CVV information a credit card number is essentially useless. Your data is 100% safe & secure.

What is a credit card validator?

It is a tool that verifies card numbers by running a computer algorithm (usually Luhn Checksum) to check the validity and can also return the card type by analyzing the Major Industry Identifier of the card.
