US Patent 7647231 Flexible mail delivery system and method

The principles of the present invention provide the ability to flexibly change the delivery point and time for a mail item, while the item is en route. The recipient, sender, or mailer may flexibly change the delivery point of the item alone or in combination with each other. While an item is en route between the sending point and the delivery point, a notification is sent to indicate that the item is in transit. In response, the delivery of the item may be changed. For example, the destination specified by the sender (e.g., the delivery address written on the item) may be changed or a delivery time may be specified. The item is then delivered to the new delivery point and/or at the specified delivery time.
