A method for providing machine-readable final destination information on mail includes the steps of electronically receiving address information of a final destination for the mail from a sender located at a mail drop box and using an interface device located at the mail drop box. A machine-readable code containing information relating to the final destination of the mail is electronically generated and then printed on a label using a label printer located at the mail drop box. The printed label is presented to the sender at the drop box so that the sender can adhere the printed label to the mail prior to inserting the mail into the drop box. Machine-readable scanners read the machine-readable code on the label to sort the mail for delivery and then mail carriers deliver the mail to the delivery point indicated by the machine-readable code on the label.
