Valid Credit Card Numbers for Paypal Sandbox
March 5th, 2010
When testing your paypal account in the sandbox you’ll sometime need a fake credit card, and the ones supplied by Paypal do not work.
The easiest way is to login/create an account in the sandbox. When you do that goto My Account > Profile > Credit/Debit Cards.
From here create a credit card, remember the information for this credit card, and yes you can leave the Card Verification Number as 000.
And there you go, a valid credit card number. Note if you save this credit card you will not be able to save it as it will be tied to a paypal account.
