I ordered goods (electronics) from Europe to USA. Now I got a letter from customs that they want to see the receipt for the goods. In the packages there are already information about the purchase, PayPal transaction ID# is on the paper in the packages. Can't the customs access PayPal and check it by themselves if they have PayPal transaction ID#. I will send them the additional paper but it takes time. So I was thinking why aren't they checking it by themselves.
They can't, that would require them to have access to your paypal account. Otherwise everyone could lookup senstive data at paypal!
