Millions of mail pieces delayed in St. Louis region, audit finds

ST. LOUIS - Millions of letters and packages have been delayed across the St. Louis region in recent months, a new audit shows, revealing a staggering backlog and staffing shortages amid ongoing mail concerns.

The U.S. Postal Service's Inspector General released findings of a wide-ranging, self-initiated audit on Monday over "delivery operations in the St. Louis, MO, area," reviewing the efficiency of operations at the St. Louis Processing and Distribution Center in St. Louis City and the St. Louis Network Distribution Center in Hazelwood.

It also tracked delivery operations at the following USPS post offices:

• Ballwin
• Clayton
• Creve Coeur
• Maryville Gardens
• O'Fallon (MO)
• Southwest Station
• St. Charles

The audit found mail delays at each of two distribution centers and seven post offices under review, along with issues in clearance times and late, canceled and extra outbound trips from the distribution centers.

The St. Louis Processing and Distribution Center had more than 2.2 million delayed pieces of mail between June 3-4, marking "the largest delayed mail volume since our field operations reviews began in 2021," according to USPS.

The audit also identified 145 job vacancies at the processing center as of May 14, 2025, contributing to delays in sorting and delivery.

Meanwhile, the St. Louis Network Distribution Center had more than than 21,000 late, canceled or extra outbound transportation trips to other regional hubs from May 1, 2024 to April 30, 2025, further straining mail operations.

USPS also found there to be "systemic issues affecting package scanning, arrow key security, and property conditions" at multiple St. Louis-area postal service sites.

These issues aren't particularly new. FOX 2 has reported of staffing shortages and weeks-long mail delays over the past year, including some packages taking cross-state detours before reaching their intended destinations.

The audit has, however, renewed attention among local politicians. Missouri U.S. Rep. Ann Wagner (R-District 3) is calling for "immediate firings" and multiple meetings with postal leadership to address these issues.

“The utter mismanagement of St. Louis area postal facilities has been a stain on our region that has severely impacted Missourians for too long," said Wagner via a news release Wednesday. I have repeatedly called for an audit and now that I have seen the results, it’s clear the problem is worse than we ever thought.  This goes beyond mere incompetence. Bad leadership and completely ineffective management have stopped Missourians from getting vital medications and legal documents and robbed citizens seeking to vote by mail of the opportunity to have their vote counted.  Our community deserves a Postal Service that fulfills its core responsibility—delivering mail—instead of abandoning basic job responsibilities like showing up and answering the phone.

Illinois State Rep. Mike Bost (R-District 12), who previously called for a USPS audit in the St. Louis region, also shared the following statement:

"The simmering frustrations of people in my district have been validated with today’s results of an independent audit of postal operations in St. Louis. Earlier this year, I appealed to the U.S. Postal Service for an audit of the St. Louis postal processing center because Southern Illinoisans have faced service failures, late utility bills, missed medications, and lost family documents for far too long. I’m thankful the Trump administration conducted the audit, identified the problems, and demanded accountability. It is past time to fix these staffing shortages, hold supervisors accountable, and get the machines in top working order."

USPS noted that postal management around St. Louis has been responsive to at least 20 recommendations made in the audit.
