USPS Built a Ballot-Screening System While Courts Told It Not To
A whistleblower says the system is rushed and untested, and a court hearing this week could decide whether it gets used for the November election.
Imagine your local election office does everything right. It processes your mail ballot request, gets your ballot ready, and takes it to the post office to mail to your house. Then the post office says it needs to check a federal list first.
That is basically what is happening right now with a new U.S. Postal Service rule, and a whistleblower says the system built to run it was thrown together so fast it might not even work. That might sound like a technical mailing dispute between two government agencies. It's not. It's about whether your ballot gets to your mailbox on time this November.
FIRST: WHOSE JOB IS IT TO DECIDE WHO GETS A BALLOT?
Normally, if your county board of elections mails you a ballot, the Postal Service's job is simple: get it to your mailbox, no questions asked, the same way it delivers your birthday cards and your electric bill. It does not decide who is and is not allowed to receive mail. That decision belongs to your state and county election office. This new rule hands the Postal Service a different job. Before it will agree to deliver a ballot at all, it wants your election office to submit your name, address, and ballot barcode into a new federal online system for approval.
WHAT HAPPENED
On March 31, 2026, President Trump signed Executive Order 14399, "Ensuring Citizenship Verification and Integrity in Federal Elections." It directed USPS to write new rules for mail ballots, including barcode and ID standards the order says will help confirm that only citizens receive and cast ballots.
In June, Postmaster General David Steiner told senators the goal was making sure the right ballots go to the right people.
Voting rights groups sued in federal court in Massachusetts. In August, Judge Indira Talwani blocked the plan, ruling it was likely unconstitutional and would create chaos and confusion for states this close to the midterms.
On August 24, the Supreme Court paused that block on a technicality, ruling the challenge had come too early since USPS had not yet published a final rule.
USPS moved fast. On August 26, it issued its final rule, called "Ballot Mail for Federal Elections." It requires every mail ballot to carry an official Election Mail marking and a unique tracking barcode, and it requires election offices to upload each voter's name, address, and ballot barcode into a new USPS online system, called the Federal Ballot Mail Portal, before USPS will accept the ballots for mailing.
That same day, a coalition of 24 Democratic state attorneys general, including Maryland's, along with Pennsylvania, sued again. Voting rights groups filed a new complaint too.
On August 28, Judge Talwani issued a fresh 14 day order blocking USPS from enforcing the rule for this fall's election while she considers a longer block. The administration is asking a federal appeals court to lift that order early, and a hearing on whether to extend it is set for Thursday, September 3.
Then, on September 1, a USPS whistleblower, represented by the nonprofit Whistleblower Aid, sent a formal disclosure to Senator Richard Blumenthal's office. It alleges USPS built the Federal Ballot Mail Portal in a matter of weeks, far faster than the nine months to a year normally needed for a system this complex, and that it was not adequately tested. It warns that one bad barcode inside a large batch of ballots, like the more than two million Maricopa County, Arizona typically mails at once, could delay or block the entire batch. Reporting since then from NPR, the New York Times, and Axios confirms USPS kept building the system through the legal fight, apparently so it is ready to switch on quickly if the courts clear the way before November 3.
WHAT SUPPORTERS OF THE RULE SAY
USPS and the Trump administration say this is about basic election security. USPS argues the rule will improve ballot tracking, help law enforcement, and reduce the risk of fraud, while leaving actual voter eligibility decisions to state election officials rather than USPS itself. White House spokesperson Lauren Bis has defended the rule as part of ensuring safe, transparent, and honest elections, and says building barcode tracking software is not new territory for USPS since it already handles this kind of system for other large bulk mail customers. A coalition of Republican state attorneys general, led by Alabama, told USPS during the public comment period that the rule addresses real vulnerabilities in mail voting and gives states useful oversight tools without taking away their authority.
WHAT THE LAWSUITS SAY
Judge Talwani, in blocking the rule, found that USPS had not presented evidence of the fraud problem it says it is solving, and that the rule creates a real risk of disenfranchising voters this close to the election. The coalition of 24 Democratic attorneys general, including Maryland's, argues the rule illegally hands USPS, an agency Congress created, power the Constitution reserves to the states: deciding how elections are run. Senator Blumenthal, citing the whistleblower disclosure, says the rollout is not just legally shaky, it is also unreliable, built too fast to work for a live national election. Election administrators warn that even if the rule survives in court, most counties do not have the staff or time to comply before ballots start going out, pointing to the sheer size of counties like Maricopa as proof the timeline does not work.
WHAT WE DON'T KNOW YET
We do not know whether Judge Talwani will extend Thursday's hearing into a longer block that lasts through November 3, or whether the appeals court steps in first. We do not know if the Supreme Court will take up another emergency request, as it already has once this cycle. We do not know whether the Federal Ballot Mail Portal actually works reliably at scale. That is the entire point of the whistleblower complaint, and nobody outside USPS has confirmed otherwise. And we do not yet know what any of this means for Maryland and Eastern Shore mail voters specifically if the rule takes effect with only weeks of runway before ballots go out.
WHAT YOU CAN DO
- If you vote by mail in Maryland, request your ballot as early as your county allows. Mail voting is proceeding under existing rules right now, but the more runway you and your county have, the better protected you are if anything changes.
- Check the Maryland State Board of Elections site or your county board of elections directly for updates, rather than relying on rumors. This situation is moving fast and details will keep changing as the courts rule.
- Watch for news out of Thursday's hearing, and share verified updates, not speculation, with friends and neighbors who vote by mail, especially seniors and voters with disabilities who depend on it most.
