Identifying Relays
Each relay (see glossary) is
identified by a number on the label of the letter
separations. The number is placed under
a diagonal line directly under the
first street number of the relay to be
served.
221.6
Number Arrangement for Flat
Separations
Each wide or flat separation contains a
series of street numbers which
generally embraces the carry-out and
relays. The first separation is the
carry-out, and subsequent separations
are for relays that cover the same
territory as the letter separations and
in the same order from lower left to
upper right. To the extent possible,
these flat separations should embrace the
same territory as for each relay
on the letter case and, therefore, should bear
the relay number of the related letter
separation and the streets and block
numbers included in each relay.
221.7
Flat cases may be configured to
accommodate Vertical Flat Casing (VFC).
The use of four and five shelf cases is
permitted under the VFC method. VFC
guidelines issued in January 1990
provide additional information concerning
this matter.
221.8
When the Vertical Flat Case (VFC) DPS
work method is used, letters may be
sorted into four, five, or six shelves.
In non-DPS environments using one,
two, or modified two-bundle systems,
and in DPS environments where the
composite bundle work method is used,
agreement between the local parties
is necessary before four or five shelf
letter cases may be used.
222
As a general rule, three basic systems
are commonly used for casing and
preparing mail for delivery in a
non-DPS environment. Management may
prescribe any one of these methods, but
for efficiency and economy, some
degree of uniformity should be
maintained. However, more than one casing
