Postage
Postage was a fee levied by a mail delivery agency for use of their services. This money was typically paid prior to delivery of the parcel.

In 2268, on Sigma Iotia II, an Iotian woman sent a letter to Boss Bela Okmyx about the laundry not being picked up for three weeks. She received the letter back with postage due, indicating that he had not paid to send the letter back. ()

Payment was often indicated by a postage stamp, a piece of paper affixed to the corner of an envelope. They were wet by saliva using one's tongue. In 2000, Shannon O'Donnel offered to help Jason Janeway and his father Henry with their campaign against the Millennium Gate. Jason assured her that "you don't want to be licking stamps for the next two days", as his dad didn't have a computer from which to e-mail those they wished to write letters to. ()

Chancellor Avel Durken put a stamp on several Malcorian documents on paper. ()
