How does a Credit Card Validator work?

A Credit Card Validator works by running a series of checks on the credit card number. These checks ensure that the number is of the correct length and format and that it contains the correct number of digits in each field.

credit card number format

A valid credit card number has several fields and each of them has a meaning. For example, the first digit of the credit card is Major Industry Identifier (MII) and the first six digits (including MII) of a credit card number are the Issuer Identification Number (IIN) also known as Bank Identification Number (BIN). These identify the institution that issued the card. The next digits are the individual account identifier. The last digit is known as the check digit and is used to verify the accuracy of the credit card number.

The Credit Card Validator specifically checks the card's Major Industry Identifier (MII), Issuer Identification Number (IIN), and Checksum Validation. Also, the tool has a Luhn Algorithm checker, which will ensure your card number is correct according to the Luhn Algorithm.

The Issuer Identification Number (IIN) table below can also be used to confirm the card issuer of the credit/debit card number you have.
