Paid

In postal history and philately, a "paid" postmark (also known as a postage-paid mark or paid handstamp) is an official mark indicating that the postage has been paid in advance by the sender. In the late 19th century P.D. or P.P were used. P.D. stands for "Payé à la destination" (French) or "Paid to Destination". P.P. stands for "Port Payé" (French) or "Postage Paid". In the first case the postage was paid the whole way to the receiver of the mail. The later could be used just to pay postage out of the country. In this case the receiver of the mail had to pay postage in the receiving country.
