Patent attributes
A system and method is provided that enables a carrier of a mailpiece, such as a national postal service, to track a mailpiece as it passes from the control of a first carrier to the control of another, second carrier. The tracking of the mailpiece continues until the mailpiece is delivered, by the second carrier, to its ultimate recipient. In this manner the first carrier, who had control of the mailpiece when first posted, can monitor the handling of the mailpiece and can calculate delivery times when the mailpiece was in the control of the second carrier. The method and system of the present invention will find particular application to a national postal service seeking to track delivery performance of internationally addressed express mail that is first domestically posted and then ultimately delivered in a foreign country by the postal service of the foreign country.
