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.
272 Comments Feedback forces me to clarify this: These are NOT valid credit card numbers.
Are you 100% sure on this or is there a chance, however slight, that the numbers above combined with a lucky guess at the expiry date would authorise?

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).

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.
