Letter Carrier Overview

120 POC Mail Volume Index

The Mail Volume Index is used to adjust the lettermail and packet volume on letter carrier routes after the route sampling has been completed.  The index is necessary to compensate for the fluctuation of lettermail and packet volume between different periods of the year.

The current City Mail Volume Index include S/L, O/S and A/O volumes.  Volumes are derived from machine sort counts, and volumes from manual sortation, bypass and presort which are derived from conversion factors 

• S/L + O/S lettermail & A/O index for the week
of the volume count – 98.0%

• Average S/L + O/S lettermail & A/O volume
counted for one route during count – 200 pieces

• Adjusted daily O/S volume
200/0.98 = 196 pieces
