I understand you're having difficulty adding certain cards to your PayPal account, and I'm sorry to hear that. If you receive a message stating the card cannot be added, this may mean the card issuer is not compatible with PayPal. For account-specific assistance, I recommend contacting Customer Support. You can contact Customer Support by clicking 'Contact' at the bottom of any PayPal page for further assistance. Support is also available through Facebook private message or Twitter direct message.
