POSTAGE DUE

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.

When the Universal Postal Union was founded in 1874 the problem with underpaid foreign mail was dealt with. 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. Later more countries started to use handstamps to indicate the amount due. Later the combination of handstamps with both the "T" and the amount missing came into use. From October 1, 1907 the rules were changed. The amount due would be charged instead of the amount missing would be indicated. The amount charged was usually double the amount that was missing.
