Paypal Sandbox Credit Card in Use Error Message

Question

Within Paypal Sandbox, when I try to add a credit card to the buyers account, I keep getting the error message "That card number is already assigned to another PayPal account." I don't get it, since Paypal just generated the number for me when I made the test account. What am I not getting here? How do I fix this?

Answer 1

You need to use another fake-but-valid credit card number. The ones of PP_MTS_Chad does not work for me but there are services out there - for example http://www.getcreditcardnumbers.com/ - which can help you to generate a new fake-but-valid credit card number.

Answer 2

Have you tried refreshing the page and generating a different credit card number? If that doesn't work, below are some test Visa credit card numbers that should work.
