USPS published a final rule late on Friday, August 21, 2026 (scheduled for formal Federal Register publication around August 26), implementing aspects of President Trump’s March 31, 2026 Executive Order 14399 on mail-in/absentee ballots for federal elections.
The final rule (95 pages) amends the Domestic Mail Manual regarding transmission of mail-in or absentee ballots for federal elections. USPS explicitly issued it so it could take effect immediately if courts lift the injunctions, aiming for readiness ahead of the November 2026 midterms. It does not apply to UOCAVA (military/overseas) ballots.
States must turn over a list of every voter getting a ballot. States must submit (via a new Federal Ballot Mail Portal) lists of individuals to whom they plan to mail ballots—essentially Mail-In and Absentee Participation Lists—including names, addresses, and associated barcode data. Lists are generally due around 30 days before the election (with later modifications allowed under state law). USPS would use these to verify outbound ballots before accepting them into the mailstream.
The rule requires unique Intelligent Mail barcodes (IMb) on both outbound and return envelopes, along with Official Election Mail markings/logos and designs compatible with automated processing. Non-compliant envelopes can be rejected/returned to election officials.
If a state refuses, USPS will not deliver those ballotsCorrect under the rule’s terms. USPS would not accept or transmit non-compliant ballot mailings (or those for voters not on the submitted list). Postmaster General statements and the rule text confirm this position. USPS maintains it is regulating use of the mail (not administering elections) and would not inspect ballot contents, collect party affiliation, or open sealed mail.
A judge appointed by Obama has temporarily blocked the rule… published anyway so it can go live the second the courts lift that blockSubstantially true. U.S. District Judge Indira Talwani (Obama appointee, District of Massachusetts) issued key injunctions, including one in June 2026 (initially covering suing states) that was later expanded (around August 11) to block implementation more broadly for the 2026 election cycle. Other rulings (including one by Judge Emmet Sullivan involving a prior NAACP settlement) also constrained the effort. USPS acknowledged the injunctions in the final rule and stated it would take no implementing actions unless/until relief is granted, while publishing the rule to enable rapid activation if that occurs.
Additional context
- The rule stems directly from EO 14399, which directed USPS rulemaking on uniform standards for mail ballot transmission and related lists (tied to broader citizenship verification efforts involving DHS).
- Multiple lawsuits challenged the EO and proposed rule on grounds including separation of powers, state authority over elections under the Constitution, lack of statutory authorization for USPS to act as a gatekeeper, and conflicts with prior settlements.
- The rule is currently blocked by court injunctions and will not be implemented unless those are lifted. As of August 22, 2026, the injunctions remain in place. The rule is ready but inactive for the midterms unless courts act. Appeals (including potential Supreme Court involvement on related issues) are ongoing in some reporting.
- Supporters frame it as election integrity and fraud prevention measures (tracking, lists for law enforcement access). Critics argue it improperly federalizes aspects of state election administration, risks disenfranchisement or delays, and creates new databases of voter data.
