USPS Publishes Final Mail-in Ballot Restriction Rules, Ready to Activate If Court Injunction Falls

The USPS published a 95-page final draft of mail-in ballot restrictions on August 21, 2026, designed to take effect immediately if a federal court injunction is lifted. The rules, responding to a March executive order from President Trump, would require states to share voter lists and add barcodes to ballot envelopes — or face a USPS refusal to deliver ballots.
