On Christmas Eve of last year, while many were setting out cookies for Santa and dreaming of sugar plums, David Steiner and the Republican-led US Postal Service pushed through a quiet-yet-consequential new rule change, impacting millions of voters in the process. This change redefined what the United States Postal Service considers a “postmark.”
Previously, a postmark reflected the date USPS first received a mailed item.
Under the new rule, it now reflects the date the item is processed, often days later.
Combined with the fact that more than 70% of post offices are located over 50 miles from regional processing centers, this change has serious implications for voters, especially those who rely on vote-by-mail.
Civitech’s work is dedicated to lowering barriers to civic participation and expanding access to democracy. This rule change does the opposite.
What Changed: The New USPS Postmark Definition
For millions of voters (especially seniors, rural voters, voters with disabilities, shift workers, and voters of color), vote-by-mail is a necessity. Under the old standard, voters could reasonably trust that mailing a ballot by the legal deadline meant their vote would count.
Under the new definition, a ballot mailed on time could still be rejected simply because it wasn’t processed quickly enough.
Thirty-six states require that mail ballots returned via the mail are received on or before Election Day. Fourteen states and Washington, D.C. will accept a mail ballot that is received after Election Day as long as it is postmarked on or before Election Day.
How the USPS Postmark Rule Impacts Vote-by-Mail Ballots
Of the fourteen states that will accept a mail ballot that is received after Election Day as long as it is postmarked on or before Election Day, Mississippi is now in dispute due to HB 908. HB 908, which was signed into law in March 2026, changes Mississippi law pertaining to federal election deadlines. The bill provides that if the U.S. Supreme issues a ruling that federal law overrides state laws regarding absentee/mail-in ballots, absentee ballots for elections involving federal offices must be received by an earlier deadline rather than the traditional five business days post election.
For the change to take effect, the bill requires the state attorney general to determine that such a U.S. Supreme Court ruling has been made and meets the criteria stated in the bill.
Obviously, that opens up plenty of potential for malicious operators to intentionally bog down processing times in the days leading up to key elections.
For example, in Washington state, roughly 4,600 ballots were rejected for late postmarks in the 2024 presidential election. In a special election just one year later, with half as many total ballots cast, that number nearly tripled to 15,000. In the short time between elections, the USPS’s Regional Transportation Optimization (RTO) initiative had eliminated evening mail collections at post offices more than 50 miles from regional processing centers. In counties where RTO was implemented, the late-postmark rejection rate reached 4.64% by early 2026, which is more than three times the rate in unaffected counties.
The same concern applies to voter registration forms, ballot cure materials, and other election-critical documents. A voter can follow every instruction, mail their paperwork on time, and do everything else “right,” yet still end up disenfranchised. That uncertainty erodes already-shaky trust in our democratic process, and discourages participation. With the midterms approaching, the stakes couldn’t be higher.

Why This USPS Rule Change Is Voter Suppression
Voter suppression doesn’t always come in the form of dramatic bans or explicit discrimination. Often, it hides behind technical changes that “just-so-happen” to disproportionately harm already-marginalized communities.
That way, the perpetrators of these suppression efforts can write their impact off as unfortunate “side effects” of new changes instead of being held accountable for electoral interference.
This USPS postmark rule change shifts responsibility from election systems onto voters, while ignoring the realities of postal infrastructure. When paired with other suppression efforts (like recent gerrymandering pushes), voters are forced to navigate a system deliberately built to impede their participation. That inequity is not accidental, and its impact will be felt most acutely by the same communities historically excluded from political power.
How Civitech Helps Voters Navigate Changing Postmark Rules
Civitech was founded to build the tools and infrastructure needed for a fairer, more equitable democracy. In short, this is what we live and breathe for.
- Our voter engagement and registration tools help organizations proactively reach voters earlier, ideally avoiding last-minute voting risks. Our products are designed to reach the same voters affected by suppression efforts like this rule change.
- Our nationwide voter file and proprietary data allow campaigns and organizations to identify voters most likely to be impacted by these changes (i.e. rural voters, infrequent voters, and members of the New American Majority) and tailor outreach accordingly.
- Our organizing platform, RunningMate, empowers leaders to adapt quickly, allocate resources strategically, and respond to suppression tactics in real time.
Democracy should not depend on how far you live from a processing center or how quickly your postal worker can rubber stamp your ballot.
Civitech will continue to stand with voters, advocates, and campaigns to ensure every eligible voice is heard, no matter how the rules change.
