You can now validate any credit cards numbers using our credit cards validator online! Our credit cards validator & checker checks the credit cards numbers & return valid results such as Major Industry Indentifier which can be checked by analysing the credit card numbers prefix. Our validator checks MasterCard, Visa, Discover Card, JCB Card, & American Express cards.
We'll check your numbers against the Luhn Algorithm to see if it is a valid credit cards numbers.
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:
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:
(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:
This makes the full account numbers read 79927398713.
Absolutely not! Credit cards numbers entered on our validator undergone process using validating rules. However, we do not store these credit cards for security purposes.
Yes! Our 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.
