Internal Controls Over Stamp Stock Shipments ― Anderson, IN, Post Office

The OIG used data analytics to identify offices with lost or stolen stamp stock shipments. We identified expenses related to stamp stock shipments between May 1, 2016, and April 30 2017, for the Anderson, IN, Post Office, and Anderson Stations B and C, two small finance stations whose stamp stock is shipped to the Anderson Post Office. When retail units do not resolve discrepancies timely, Accounting Services records an expense to the units for the difference. The objective of this audit was to determine whether internal controls over stamp stock shipments were in place and effective at the Anderson Post Office.
