Origin-Destination Information System - Revenue, Pieces, and Weight (ODIS-RPW) is the primary probability sampling system used by the U.S. Postal Service to assist in estimating mail revenue, volume flow, and weight. As part of this system, data collection technicians test and record mailpiece characteristics, such as shape, postmark date, and origin ZIP code. Management observes and reviews these tests to ensure that data collection technicians employ proper procedures and that the data is accurate. Our objective was to determine whether the Postal Service conducted ODIS-RPW tests in accordance with established policies and procedures.
