Credit card numbers

Credit card numbers that conform to the Luhn formula (MOD 10 check). Usefull for testing e-commerce sites (because they should get past any pre-validation you do, and be declined at the card processor or bank stage).

In testing situations any expiry date within the next 3 years should work

Feedback forces me to clarify this: These are NOT valid credit card numbers. You can’t buy anything with these. They are random numbers that happen to conform to the MOD 10 algorithm. They are a technical resource for programmers – that’s all.

Information about CVV2 / CVC / etc numbers can be found here: CVV numbers. As you can see these would be very hard to calculate without the bank’s keys.

A very good article about the credit card number format can be found here: Anatomy of Credit Card Numbers

As you can see below I get a lot of feedback about this page. Thanks to everyone who stops by to write a note, it is appreciated. Before you ask no I haven't got anyone's credit card details. Instead take a look at some of the amusing feedback I have received by e-mail.
