Mail encoding and processing system
First Claim
1. Apparatus for automatically sorting mail comprising optical character reader means, means for receiving pieces of mail and feeding them to the optical character reader means, the optical character reader means being arranged to read a delivery address including a postal code corresponding to the delivery address on each piece of mail and generate an output and computer means receiving the output from the optical character reader means and generating a stop identifier suffix based on the address and postal code only whereby the postal code and the stop identifier suffix together form a point of delivery identifier which uniquely identifies a final delivery address.

Abstract
Mail can be sorted automatically to point of delivery level by deriving from the address including postal code on a piece of mail a suffix which together with the postal code forms routing data which uniquely identifies the final delivery address. This is achieved automatically at the Post office sorting facility by means of an optical character reader which reads the addresses on mail items and a computer arranged to generate a suffix based on the address read. The routing data is printed as a bar code on the mail item and this allows the complete sortation to be effected automatically. Also contemplated is a progressive encoding system which can be applied as bar codes by customers as desired to mail pieces. The basic data is the routing data set to which can be added a shipment number which allows automatic revenue accounting control and a piece number which allows automatic track and trace. Finally, the customer may also progressively encode return mail envelopes with the shipment number followed by a product code and a user defined field which permits automatic specialized handling of the return mail item.

6. A method of encoding and decoding mail pieces, at least some of which contain return mail items, the method comprising determining from an address list a stop identifier suffix for a delivery address on the mail piece, said stop identifier suffix combined with a postal code corresponding to the delivery address forming a routing data set uniquely identifying a final delivery address, the customer applying to a designated area of each piece of mail a machine readable code comprising a specific routing data set representing routing information, an optional shipment number forming with the routing data set a revenue accounting data set, and an optional piece number forming with the revenue accounting data set a track and trace data set, the customer also applying to a designated area of the return mail items a machine readable code comprising the shipment number followed by an instruction code and a user defined field, decoding in the Post Office the mail pieces by an optical character reader each data set and automatically sorting the mail according to the routing data set, automatically computing account information based on the revenue account data set and automatically tracking the mail pieces based on the track and trace data set and when the return mail items are returned in the mail, decoding in the Post Office by an optical character reader the machine readable code on the return mail items and automatically computing account information.
