How Credit Card Validator Works

Credit Card Validator

You could wonder: how the validator is able to check whether a particular card number is a valid one if such a credit or debit card does not exist at all? The answer is simple: every card number contains several integral elements that make up a complete number, namely:

  • The first digit serves as the identifier of the industry (the Major Industry Identifier or MII).
  • The first six figures, including the MII, make up the IIN – the Issuer Identification Number – which identifies the company that issued the card.
  • The following figures, until the last one, stand as a card/account number.
  • The last digit is used to check whether the number of the card is real by using a simple formula, known as the Luhn formula.

Thus, the credit card validator is able to recognize a valid credit card number, while separating it from the invalid ones. In addition to that, the validator will help you to find out which company had issued the credit card in case if the credit card number is a valid one.

The last digit in every credit card number is used for recognizing whether it is a number of a real credit/debit card or not. The Luhn formula, known also as the Luhn algorithm or the mod 10 algorithm, is used not only by the financial companies, but also by the governments.

If you have a mistake in the number of a credit card, the credit card validator will show where you have a mistake exactly (in which of the four above mentioned parts).
