Mailpiece Characteristics  
Understand the elements of your mailpiece.
Mailpieces must have specific characteristics to be processed efficiently. Characteristics include height, length, thickness, weight, and aspect ratio.

The MERLIN™ program verifies all of these attributes to ensure that mailpieces meet the rates claimed.
