Please follow the recommendations in this booklet for accurate and efficient
processing of your flat-size mail. These guidelines are intended to enhance,
but not replace, standards found in the Domestic Mail Manual.
New Postal Service automation
equipment is capable of processing
flat-size mail at a rate of over 17,000
pieces per hour! This high speed
processing not only helps to hold
down postal operating costs and,
consequently, postage rates, it also
enables consistency in on-time mail
delivery. High readability of barcode
and address information is a critical
component of automation success.

The delivery address should be at least 1 inch lower and 1 inch to the right
of the return address, assuming both addresses read in the same direction.
On a flat-size mailpiece, in a landscape orientation, the delivery address
should be separated as much as possible from the return address.
The delivery address block must be clearly separated from any extraneous
text and graphics. Provide a minimum clear area of 3/8 inch (1/2 inch is
recommended) in each direction around the address block.
Avoid skew (keep tilt less than 5 degrees off the horizontal or vertical axis).
To facilitate Postal Service delivery operations, the preferred delivery
address block location for flat-size mail with a portrait orientation is in the
upper right-hand quadrant of the mailpiece adjacent to the bound edge.
This is particularly true for mail without a return address. When the
orientation of the piece is landscape, the delivery address should appear in
the lower right-hand quadrant.
Refer to diagrams on pages 5–8 for preferred address placement.
