Delivery Mode Conversions Could Yield Large Savings, but More Current Data Are Needed
May 12, 2014
What GAO Found
The U.S. Postal Service (USPS) estimates of delivery mode costs and potential savings from converting to less costly modes show that door-to-door delivery is much more costly than delivery to a curbside or centralized mailbox and that USPS could achieve large savings by mandating large-scale conversions from door delivery to other modes. For fiscal year 2012, USPS estimated average annual costs of about $380 per delivery point for door delivery, compared with about $240 for delivery to the curb, and about $170 for delivery to a central location. USPS also estimated potential ongoing savings of over $2 billion annually from mandating conversion of about one-third of door deliveries to other modes. However, USPS's estimates of these specific costs and savings have limitations, in part because they rely on data from a 1994 USPS study. In lieu of current data, USPS adjusted the 1994 data according to increases in the Consumer Price Index—an adjustment that may not have been the same as changes in USPS delivery costs, which are affected by factors such as increases in postal wage rates, postal benefit costs, and gasoline prices. USPS officials estimate a new study could be conducted to replace the 1994 study for a total of about $100,000 to $750,000, depending on the extent of the study. Without current information on costs of delivery modes and on potential savings through delivery conversions, USPS and lawmakers may not have an accurate understanding of the impact of delivery mode changes on which to base their decisions.
