We'll check your numbers against the Luhn Algorithm to see if it is a valid credit cards numbers by **credit cards validator** .

The first digit of credit cards numbers represent the category of entity which issued the card.

The first six digits of a cards numbers identify the institution that issued the cards to the card holder.

Digits 7 to final numbers minus 1 (the last is the checksum) indicate the individual account identifier.

We check for the following:

- First Digit - Major Industry Identifier
- Six Digit - Issuer identification number
- Seven Digit - Personal Account Number and Checksum

The Luhn formula or Luhn algorithm , also known as the "mod 10" or "Modulus 10" algorithm, is a simple checksum formula used to validate a variety of identification number, such as credit cards numbers, IMEI numbers, National Provider Identifier numbers in the Usa , Canadian Social Insurance Numbers, Israel ID Numbers & Greek Social Security Numbers (ΑΜΚΑ). It was created by IBM scientist Hans Peter Luhn and described in U.S. Patent No. 2,950,048, filed on January 6, 1954, & granted on August 23, 1960. [source:wikipedia]

Assume an example of an account number "7992739871" that will have a check digit added, making it of the form 7992739871xx:

The sum of all the digits in the third row is 67+x.

The check digit (x) is obtained by computing the sum of the non-check digits then computing 9 times that value mod 10 (in equation form, ((67 × 9) mod 10)). In algorithm form:

- Compute the sum of the non-check digits (67).
- Multiply by 9 (603).
- The units digit (3) is the check digit. Thus, x=3.

(Alternative method) The check digit (x) is obtained by computing the sum of the other digits (third row) then subtracting the units digit from 10 (67 => Units digit 7; 10 − 7 = check digit 3). In algorithm form:

- Compute the sum of the non-check digits (67).
- Take the units digit (7).
- Subtract the units digit from 10.
- The result (3) is the check digit. In case the sum of digit ends in 0 then 0 is the check digit.

This makes the full account numbers read 79927398713.

Absolutely not! Credit cards numbers entered on our **credit cards validator** undergone process using validating rules. However, we do not store these credit cards in **credit cards validator** for security purposes.

Yes! Our **credit cards validator** only checks the Major Industry Identifier or MII, the Personal Accounts Numbers and Issuer Identification Number. You can reads the detailed table for MII Below.

MII Digit | Category |
---|---|

0 | ISO/TC 68 & other industry assignments |

1 | Airlines |

2 | Airlines, financial & other future industry assignments |

3 | Travel & entertainment |

4 | Banking & financial |

5 | Banking & financial |

6 | Merchandising & banking/financial |

7 | Petroleum & other future industry assignments |

8 | Healthcare, telecommunications & other future industry assignments |

9 | For assignment by national standards bodies |

Using the table you assumed that Visa which starts with number 4 belongs to Banking & financial as well as MasterCard which is prefixed with numbers 5.

- 4 for Visa - Banking and financial
- 5 for MasterCard - Banking and financial
- 3 for Discover Card - Travel and entertainment
