The U.S. Postal Service is moving ahead with a sweeping overhaul of how mail-in ballots are handled.
The move comes after President Donald Trump’s March 2026 executive order aimed at strengthening election security, improving ballot tracking, and ensuring that only eligible U.S. citizens participate in federal elections.
The initiative represents one of the most significant federal efforts in decades to standardize procedures surrounding mail-in voting and absentee ballots.
At the center of the order is a directive requiring the USPS to launch a formal rulemaking process establishing nationwide standards for the transmission of mail-in and absentee ballots through the federal mail system.
The White House points out that existing safeguards are inconsistent across states and that additional protections are needed to maintain public confidence in election outcomes.
The executive order correctly states that voting in federal elections is exclusively for American citizens and notes that several existing federal statutes already prohibit non-citizens from registering to vote or casting ballots.
The administration argues that stronger verification systems can help ensure compliance with those laws while also protecting the integrity of elections conducted through the mail.
The order directs the Department of Homeland Security, working in coordination with the Social Security Administration, to compile and distribute State Citizenship Lists to election officials.
These lists would be derived from federal citizenship records, naturalization records, Social Security data, the SAVE database, and other federal sources.
The lists would identify individuals confirmed to be U.S. citizens who are at least 18 years old and reside within a given state.
The administration emphasizes that inclusion on a State Citizenship List would not automatically register an individual to vote; rather, the lists would serve as a resource to assist states in maintaining accurate voter rolls and verifying voter eligibility.
States would still retain responsibility for registration procedures and compliance with state election laws.
The Postal Service component of the order introduces several new requirements for mail ballots.
Under the proposed rules, all outgoing ballot envelopes would need to be clearly marked as Official Election Mail and include a unique Intelligent Mail barcode or comparable USPS tracking technology.
These identifiers would allow election officials and postal authorities to track ballots throughout the mailing process and provide a more detailed audit trail.
In addition, ballot envelopes would be required to undergo a USPS design review to ensure compatibility with postal automation systems and compliance with federal mailing standards.
The administration notes that standardized envelope designs could reduce processing errors and improve ballot delivery reliability.
Another major component of the proposal involves the creation of Mail-In and Absentee Participation Lists.
States choosing to participate would submit lists of voters authorized to receive mail-in ballots before federal elections.
USPS would then maintain records of ballot recipients and assign unique ballot envelope identifiers associated with those voters.
The system is intended to ensure that ballots are transmitted only to authorized recipients and that every ballot can be tracked from mailing to delivery.
The order further proposes that USPS not transmit mail-in or absentee ballots from individuals unless they are enrolled through the state-specific participation system outlined in the regulations.
States would also be permitted to update and supplement these lists as elections approach.
Beyond ballot tracking, the order directs the Department of Justice to prioritize investigations into election-related offenses, including instances in which ballots are issued to individuals who are not legally eligible to vote in federal elections.
The Attorney General is instructed to focus enforcement efforts on violations involving election administration, ballot distribution, and fraudulent voting activity.
The USPS would also be required to coordinate with the Postal Service Office of Inspector General and the Department of Justice regarding suspected unlawful use of the mail involving federal election materials.
According to the order, these partnerships are intended to improve oversight and facilitate investigations when potential violations occur.
