Postage due is the term used for mail
sent with insufficient postage. A postage due stamp is a stamp added to an
underpaid piece of mail to indicate the extra postage due.
The problem of underpaid foreign mail was one of the issues addressed by the 1874 establishment of the Universal Postal Union. The U.P.U. arrived at the decision that mail with insufficient postage should be marked with a "T" and from April 1, 1879 the amount missing would also be indicated in black.
From October 1, 1907 the rules were changed. The amount to be charged instead of the amount missing would be indicated. The amount charged was usually double the amount that was missing.
In 1859, first Postage Due Stamps was issued. It was affixed at the delivery office before being taken out to the recipients. Many other countries followed suit.
