The USPS Office of Inspector General published a 30-page audit confirming significant delivery delays across South Dakota. The report found that mail is being inefficiently routed to facilities in other states due to recent processing changes.
Why it matters
The findings highlight how the USPS Delivering for America modernization plan has negatively impacted local service. Residents and businesses have faced delivery frustrations because mail is often traveling out of state for processing.
An audit of 120 Priority Mail packages confirmed that more than 30% were sent out of state for processing. Some mail pieces were routed as far away as a distribution center in Royal Palm, Florida.
