GAO Finds USPS Cost Cutting Contributed to Declining Mail Service

Postal employees often hear two messages at once: reduce costs and improve service. A new Government Accountability Office report examines how USPS has managed that tension and finds that the results still fall short.

Released September 17, GAO-26-108527 reviews changes since the 2021 launch of the Postal Service's strategic plan. It examines delivery expectations, network and transportation changes, customer impacts and USPS's response to performance problems. Its central concern is whether USPS can demonstrate a credible route to better service while pursuing financial sustainability.

Slower standards and lower targets are different changes

A service standard describes the expected delivery time for a mailpiece. A performance target is the share of mail USPS expects to deliver within that standard. Changing either affects how results should be understood.

GAO describes longer delivery expectations for some First-Class Mail associated with the shift from air to ground transportation and later transportation changes. Separately, USPS lowered the percentage of mail it expected to deliver on time. The report finds USPS still missed most of its targets after those reductions.

That distinction matters when a percentage is presented as evidence of improvement. Readers need to know both the delivery window being measured and whether the target itself changed. Comparing two percentages without that context can conceal a change in what “on time” means.

The report examines the network, not just the last carrier stop

GAO focused on three initiatives: the move from air to ground transportation, processing and delivery network redesign, and Regional Transportation Optimization. It reviewed USPS data and documents, earlier oversight work, and interviews with USPS, regulators and selected mailing-industry stakeholders.

The report connects some slower service to these system changes and describes a disproportionate effect on rural customers reported by oversight bodies and stakeholders. That does not mean the report proves why a particular customer's letter arrived late. Individual delays still require a trace of the actual mailpiece and its movement.

What GAO recommends—and what USPS agreed to

GAO recommends that USPS's next strategic-plan update describe its ongoing and planned service improvements, their expected effect on performance targets, and the challenges that could interfere. The report identifies an update planned for 2027 as an opportunity to provide that explanation. USPS agreed with the recommendation.

The recommendation does not itself reverse a consolidation, restore an afternoon dispatch or establish a new local staffing complement. It asks USPS to make its improvement plan and expected results clearer to Congress, the public and other stakeholders.

What it means for postal employees

MyPostalPay analysis: The report supports evaluating service across the entire mail flow. A delivery unit can complete its assigned delivery work and still face complaints about mail that spent additional time elsewhere. Conversely, citing a network problem does not establish that every local procedure was followed correctly. Both questions need evidence.

For employees handling customer inquiries, the useful approach is to distinguish what the tracking or service record actually shows from what remains unknown. For managers evaluating workhours, a local reduction is only part of the result if work or delay shifts to another operation. For employees following restructuring news, this report offers evidence about service outcomes without predicting a specific job action.

What to watch next

The next test is whether USPS publishes concrete improvement actions, measurable expectations and progress against them. Watch for the 2027 plan update and GAO's follow-up on its recommendation. A promised improvement has more value when readers can see the baseline, the target and the result.

This report adds a service-performance dimension to the postal financial debate. It does not settle every proposal for the agency's future, but it makes the tradeoffs harder to discuss solely in terms of projected savings.
