The Postal Service uses a label system to control the flow of priority rate service mail on specified flights from origin to final destination. Each mail handling unit (pouch, tray, etc.) receives a label indicating the routing with flight number, weight, and scheduled delivery day.
The Postal Service uses a label system to control the flow of non-priority rate service mail and bypass mail from origin to final destination. Each mail handling unit (parcel, pouch, tray, pallet, etc.) receives a label indicating the routing, weight, and scheduled delivery day.
In addition to routing information described in 6-3.2.1 and 6-3.2.2, each Label AK-53 contains the delivery day of the week printed in large type. Administrative officials at both the origin and destination must be cognizant of the delivery day shown on the label and report, through the irregularity process, when mail is delivered after the scheduled delivery day.
Note: Mail delivered before the scheduled delivery day is not considered an irregularity, and administrative officials should not report it as such.
