Credit Card Validator



credit card number generator.

Welcome to CreditCardValidator! This site is a free resource that tracks credit and debit card IINs (Issuer Identification Numbers) and BINs (Bank Identification Numbers), which are the portion of a credit card number that can be used to identify the card type and issuing bank. Credit Card Validator. Credit Card Validator provides validation utilities for credit card data inputs. It is designed as a CommonJS module for use in Node.js, io.js, or the browser. It includes first class support for 'potential' validity so you can use it to present appropriate UI to your user as they type.

At Fakecreditcard.co you can easily generate major credit card numbers such as Visa card, MasterCard, American Express, JCB Card and Discover Card.
The credit cards numbers are digits generated based on a mathematical formula that complied with the standard format of the Luhn algorithm (mod 10). The Luhn algorithm formula is used to validate the generation of credit card numbers by using the combination of the BNI (bank identification number) or IIN(issuer identification number) which is mostly about six digits, the account number which ranges from 6 to 9 digits (used to identify the cardholder’s account number) and then the check digit which is the last number added to confirm the authenticity of the credit card.

Generating a credit card number The Luhn algorithm has two basic ways of logically validating the generation of a credit card number in the following ways:

Credit Card Validator
1. When the modulo of the addition of the newly generated credit card number equals to 0, then we would say that the credit card number passes the Luhn algorithm test. Hence, making the generated number valid.
2. When the modulo of the addition of the newly generated number does not equal 0 that is (1-9), then the conclusion that the generated credit card number is invalid since it does not passes the Luhn algorithm test.

Additionally, you can generate credit card number by simply assigning number prefixes using the MII number of Major Industry Identifier Number. Using the table below.

These credit card numbers DO NOT work! They are for testing purposes only. Without a valid owner name, an expiration date and a valid CVV code, they can't be used for real transactions. You should use these numbers only to test your validation strategies and for bogus data. Note that the algorithm used here is freely available across the web even Wikipedia.org. These numbers were generated randomly.You can refresh the page to get new numbers.

How to validate a Credit Card Number?

Most credit card number can be validated using the Luhn algorithm, which is more or a less a glorified Modulo 10 formula!

Credit

The Luhn Formula:

  • Drop the last digit from the number. The last digit is what we want to check against
  • Reverse the numbers
  • Multiply the digits in odd positions (1, 3, 5, etc.) by 2 and subtract 9 to all any result higher than 9
  • Add all the numbers together
  • The check digit (the last number of the card) is the amount that you would need to add to get a multiple of 10 (Modulo 10)
