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.

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.
