What is credit card validation?

The credit card number, also known as PAN (Primary Account Number), is the long number embossed in the front of your credit card. The number contains essential information strategically organized and internationally standardized. That information includes the cardholder's name, security code, account number, issuing bank name, and expiration date.

Credit card validation is the process of validating the genuineness of a credit card. That process gains importance as monetary affairs become sensitive.

The credit card number is generated under specific protocols and rules. It gives a merchant a facility to validate the credit card number before accepting a customer's payment.

There is a wide range of algorithms created by several finance companies to validate a credit card. The practical use of these algorithms will allow you to validate whether the credit card is genuine or not.

The online credit card validator gives you the room to validate the credit card at any time, at any place, where you have internet access, in a split of seconds.

How can a credit card validator help in validating a credit card number?

The online credit card validator assists you in validating a credit card in real-time. You can get the following information from the credit card validator tool.

  1. Major industry identifier (MII): Your credit card's first primary number is MII (Major Industry Identifier or Main Sector Identifier). That defines the industry in which the card is mainly used. The various MII numbers represent the following categories.
    • 0: ISO / TC 68 and other industry duties
    • 1: Airlines
    • 2: Airlines, finance, and other future industry duties
    • 3: Travel and leisure
    • 4: Banking and finance
    • 5: Finance and banking
    • 6: Sales and banking/finance
    • 7: Petroleum and other future industry tasks
    • 8: Healthcare, telecommunications, and other future industry tasks
    • 9: For the appointment of national standards bodies
  2. BIN/IIN (Bank/Issuer Identification Number) check: The first six digits of the credit card number determine the institution that issued the credit card to the cardholder. The online tool allows you to extract information like your Bank Name, Bank Address etc.
  3. Personal account number check: The online tool provides you an opportunity to verify your account number by entering your credit card number. You may have an idea that from digit seven to the final number minus the last one is your account number.
  4. Luhn Algorithm Check: The online tool uses the Luhn algorithm to validate the credit card number, also known as the MOD 10 algorithm. It's a formula that scientist Hans Peter Luhn develops from IBM.

    To teach how that algorithm manually works, let's do an example.

    Suppose we have a credit card number 347609692102916, and we want to check if it's a valid credit card number or not.

    • Take the last digit 6. That is our check digit.
    • Take the rest of the sequence 34760969210291.
    • Double every other digit starting from the right 3,8,7,12,0,18,6,18,2,2,0,4,9,2.
    • Sum the digits of the products 12 = 1 + 2 = 3, same with 18 that gives you 9.
    • Add all the digits together 3+8+7+3+0+9+6+9+2+2+0+4+9+2 = 64.
    • Multiply the result by 9, 64 * 9 = 576.
    • Take the last digit of the result 6. If this matches the check digit, then we have a valid sequence.
    • Since our check digit 6 matches our result 6, we conclude that this sequence is a valid credit card number.
  5. Credit card prefix numbers check: Each credit card issuer has a varying credit card number length, usually 13, 14, 15, or 16 digits, and some even have 19 digits. The following list will help you in understanding the length of various cards.
    • AMEX: start with 34 or 37 and has 15 numbers.
    • Diners: start with 300, 301, 302, 303, 36, or 38 and has 15 numbers.
    • Discover: start with 6011 and has 16 numbers.
    • Enroute: start with 2014 or 2149 and has 16 numbers.
    • JCB 15: start with 2100 or 1800 and has 16 numbers.
    • JCB 16: start with 3088, 3096, 3112, 3158, 3337 or 3528 and has 16 numbers.
    • MasterCard: start with 51, 52, 53, 54, or 55 and has 16 numbers.
    • Visa: start with 4539, 4556, 4916, 4532, 4929, 40240071, 4485, 4716 or 4 and has 13 or 16 numbers.
    • Voyager: start with 8699 and has 13 or 16 numbers.
