About Credit Card Validator

Credit Card Validator: A Complete Beginner's Guide


Through the Luhn algorithm, Credit Card Validator helps implement validations for credit cards and various identification numbers like credit card numbers, IINs (Issuer Identification Numbers), BINs (Bank Identification Numbers), prefixes, etc.


Credit Card Validator uses the Luhn algorithm or mod 10 algorithm. This simple checksum formula uses the account number and checksum digits to determine if a card is valid. It works with major credit card brands, including VISA, MasterCard, American Express, Diner's Club, and JCB.


How does a credit card validator work?


The way a Credit Card Validator works is very simple. Using the Luhn Algorithm, the account number and checksum are used to determine if a card is valid. A credit card validator can work in two ways: -


Manual Validation


  • Write down the last number on your credit card. This is the checksum number, which helps ensure the rest is correct.

  • Write down each digit of your credit card number, going from the left of the checksum to the right.

  • If you have a 16-digit credit card number, double each number from right to left.

  • If you have a credit card with 15 digits, multiply the digits in a number more than 10 by two, add the two digits of a new number together, and add the result to your list.


For instance, if the number also on the card is 7, then 14 will result from duplicating it. And the two numbers will add up to five. Don't count the checksum digit when you add the numbers to your list. The credit card number is valid if you divide the total by 10. Don't go through with the credit card transaction if you can't.


Online validation


  • Use our tool to go to an online credit card validation service.

  • Enter the type of credit card, the card number, and the date it expires, and then click "Submit" to validate your card.

  • Just wait for the website to confirm that you're valid. If the credit card is considered valid, the card is validated. If the card is not valid, the transaction cannot be processed.


Types and Layouts of Credit Cards


American Express (Amex), Discover, Mastercard, and Visa are the four main types of credit cards used worldwide. Customers get their credit cards from Amex and Discover the two biggest credit card networks. 


Mastercard and Visa networks, on the other hand, get their cards from a secondary bank or other banking institutions. Credit card formats change all the time, but most cards have a few things in common, like the Name of the card issuer, the Name of the cardholder, and the card number.


  • The bank that gave you the credit card is called the "Credit Card Issuer."

  • This credit card has a name that starts with "Credit Card Name." The Name of the card starts with the Name of the bank that issued it, followed by the Name of the card itself.

  • Credit Card Network is the company that processes payments made with Visa, Mastercard, American Express, and Discover cards.

  • Cardholder's Name is the card's owner's Name.

  • The credit card number is the number on the magnetic strip used to identify the card.

  • The information about the cardholder is stored in the chip.

  • The date of opening an account is when a credit card account was made.

  • The date that this card will stop working is written on the back.

  • The CVV Security Code is on the back of credit cards. It is used to stop unauthorized transactions and stop fraud. The CVV code is a three-digit number for Visa, Mastercard, and Discover, but it is a four-digit one for Amex.

  • A magnetic stripe on the back of your credit card holds all your account information.
