The U.S. Postal Service (USPS) is implementing operational changes that election officials warn could lead to the rejection of mail-in ballots due to late postmarks. Because postmarks are often used to determine if a ballot was sent by Election Day, officials are recommending that voters returning ballots close to the deadline do so at local election offices, drop boxes, or by requesting manual postmarks at a post office.
The potential for delays stems from the "Regional Transportation Optimization" (RTO) effort, a component of a 10-year financial stabilization plan initiated in 2021. Since April 2025, the USPS has implemented processing changes and reduced daily mail pick-ups, particularly in rural areas. These changes mean that mail dropped in collection boxes or picked up by carriers may not be stamped with a date on the same day it is received.
To address these concerns, the USPS announced "extraordinary measures" for the upcoming federal general elections. Starting October 26, 2026, post offices affected by RTO have been instructed to separate ballots from other mail so managers can manually apply postmarks on the day of collection. Additionally, beginning October 24, some locations may extend hours by 30 minutes and establish dedicated lines for manual postmarking.
For the individual voter, these changes mean that a ballot dropped in a standard blue mailbox on the eve of an election might not receive a valid date stamp in time to be counted. To ensure a vote is recorded, a person may need to visit a post office in person to request a manual stamp, a task that could take longer starting October 24 due to potential wait times, or they may have to locate a physical drop box. While the USPS states it will speed up delivery starting October 26, the agency continues to recommend that all voters mail their ballots at least one week before their state's specific deadline to account for processing variables.
The implementation of these measures represents a shift from previous election cycles. In 2022 and 2024, the USPS began extraordinary measures 15 days before the election; for 2026, the window has been shortened to 10 to 11 days. The USPS maintains that these timelines are based on internal factors and its long history of handling election mail. What happens next depends on the performance of local post office staff in executing these directives; the general election will take place on November 3, 2026, serving as the final deadline for postmarking in many jurisdictions.
