l have a us bank checking account and l have a card for it... but not on me. and for paypal to work correctly they need more than just your account number. sooo l am logged into my us bank account and it only shows the last four numbers of the card.. grr how can l find my FULL card info?

You can not. Wait until you have the card on you to fill out the paypal information. In addition to the card number they will need the expiration date and probably the 3 digit number on the back of the card.

You will not be able to see this information online, for your own protection. It might sound stupid at the moment, but think if someone hacked your computer and stole your passwords and then had access to your actual full account info.
You're going to have to wait until you have the card on you, sorry :(

You will not be able to access your full card number online for security reasons, so your best bet is to wait until you have the physical card to input the info-- and unless you know the expiration date and the 3 digit CVV number on the back you wo not be able to use it anyway!
