From the OIG Report: Our objective was to assess the Postal Service’s First‑Class Mail and Priority Mail service performance since fiscal year (FY) 2022. The review looked broadly at service performance changes, trends, failure points, and causes.
Challenges implementing major changes to the Postal Service network over the last few years has negatively impacted service performance. Despite lowering standards, the amount of First‑Class Mail and Priority Mail delivered on time decreased five and percentage points since FY 2022, respectively. The Postal Service is operating in a transitional state, with many additional changes still to be implemented. It is likely service will continue to be suppressed during this time, even with the Postal Service reducing its target for First‑Class Mail delivered on time by 4.5 percent in FY 2025. We identified opportunities to enhance operational performance, decrease cost, and improve service.
