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!
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)
