Shipping/Billing addresses

Hi, I would like to know- does Payoneer ever send anything more (like letters, some kind of bills, adverts or anything like it) than just a card at the beginning? And if they do- do they send that to the billing address or to shipping address? Or is shipping address only needed for sending a card, and then this address is not used by payoneer at all (nothing is sent there unless I want a new card)? I hope you understand what I am asking about. Thank you in advance :)
