During fiscal year 2019, we reviewed package scanning procedures at 25 Postal Service delivery units to determine if employees were properly scanning packages. During our audits, we found that Postal Service employees were not always following package scanning procedures at 21 of the 25 units. Customers rely on accurate scan data to track their packages in real time. When employees do not scan mailpieces correctly, customers are unable to determine the actual status of their packages. By improving scanning operations, management can potentially improve mail visibility, increase customer satisfaction, and enhance the customer experience and the Postal Service brand.
