Credit Card Number Generator - Validator
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!
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)

| Reverse the digits: | 5 | 8 | 9 | 9 | 8 | 6 | 8 | 5 | 7 | 3 | 7 | 6 | 5 | 5 | 4 | ||
| Multiple odd digits by 2: | 10 | 8 | 18 | 9 | 16 | 6 | 16 | 5 | 14 | 3 | 14 | 6 | 10 | 5 | 8 | ||
| Subtract 9 to numbers over 9: | 1 | 8 | 9 | 9 | 7 | 6 | 7 | 5 | 5 | 3 | 5 | 6 | 1 | 5 | 8 | ||
| Add all numbers: | 1 | 8 | 9 | 9 | 7 | 6 | 7 | 5 | 5 | 3 | 5 | 6 | 1 | 5 | 8 | 85 | |
| Mod 10: | 85 modulo 10 = 5 (last digit of card) | ||||||||||||||||
