Review of the U.S. Postal Service's Revenue Protection Function

A limited review was conducted of the Postal Service's revenue protection activities in order to determine whether the agency had adequate controls to assure that it was receiving the proper postage from bulk mailers. All classes of mail were reviewed, but special attention was directed toward large second-class mailers since opportunities for underpayment seemed most prevalent in this class. The western region's Revenue Protection Program was also examined.
