Yes! You can attach a prepaid card to your PayPal account. We were successfully able to add Amex Serve, Green Dot & NetSpend to our PayPal account. I do believe users must also attach 1 bank account to PayPal in order to use it without limitations and this is where Green Dot comes in handy again. Green Dot for unknown reasons are capable of passing the test when trying to add it to PayPal as a bank account. Many other prepaid cards cannot do this. If you try to attach a prepaid card as a bank account in PayPal I would strongly recommend Green Dot.
