Test Credit Card Numbers (Luhn Algorithm)?

For Website Test Orders...

[olimits7]

Hi,

Does anybody know if there is any software or website that lists at least 20-30 different test credit card numbers?

I need test credit cards in a Visa, MC, Amex, and Discover card formats.

I want to create test orders on my website to make sure my encrypted credit card numbers functions properly with my back-end order management software.

I would use any numbers, but my website uses the luhn algorithm for credit cards; so if I type a credit card that doesn't meet that algorithm I can't submit any orders.

Thank you,

Isn't the Luhn checksum the last digit of the card number? Any random sequence of 16 digits should pass 10% of the time. If a sequence doesn't work, add 1, and retest. You'll find a number that meets the Luhn test in seconds.

After reading this yesterday I went over to Wiki and read their explaination just to get it clear in my head.

In our office we always wondered what "Luhn" error meant on our credit card machines.

Now we know. Thanks for bringing it up.
