POUCHING, SACKING, OR TRAYING
OUTGOING OFFICIAL MAIL
A pouch is a mailbag identified by the leather
strap-locking device on the neck of the pouch. The
pouch is commonly used for First-Class Mail, Priority
Mail, and Space Available Mail. Use the special blue
and orange pouch for Express Mail service.
A sack is a bag used to transport nonpreferential
Periodicals and Standard Mail. It is closed with a draw
cord and fastener.
A tray is used for flats or letters, depending on the
tray dimensions. A flat tray is a four-sided tray, 18
inches by 21 inches by 24 inches inside. A letter tray is
12 or 24 inches long with inside dimensions of 11
inches by 3 1/4 inches.

other outgoing mail. This is the first step in the

trayed by classification and service, considering
priorities, transportation policies, and cost. All MPOs
must use the following general guidelines when

Mail pouches, and First-Class letter mail in
orange Priority Mail No.1 pouches or in
Managed Mail (MM) letter trays.

other mail must not be pouched but must be
dispatched as outside pieces (OSPs).
