Trump Mail Rules Hit New Restraining Order as States Face Compliance Deadlines

Federal efforts to impose new tracking and verification requirements on mail ballots have collided with state election calendars and court orders two months before the 2026 midterms. An executive order issued in March directs the U.S. Postal Service to process ballots only when states supply complete voter lists for cross-checks against federal citizenship records, mandates intelligent mail barcodes and specific envelope markings, and requires 90 days’ advance notice. The Supreme Court permitted the order to take effect temporarily last week, but a federal judge in Massachusetts issued a 14-day restraining order blocking enforcement, leaving states uncertain whether to reprint envelopes or alter mailing schedules.

Litigation continues. Voting rights groups and more than 20 states argue the rules exceed federal authority under the Constitution’s Elections Clause and the 1993 National Voter Registration Act. USPS officials have raised internal concerns that a single unverified barcode in a bulk mailing could halt an entire batch, a risk highlighted in a whistleblower disclosure to Sen. Richard Blumenthal and in discussions at an August election officials’ conference. Election vendors note that most counties lack the required barcodes and that redesigning envelopes and uploading voter files in the remaining weeks carries high error potential.

States fall into distinct categories. All-mail states such as Colorado, Oregon, and Washington, plus California where 81 percent of 2024 voters used mail ballots, face the largest reprinting costs. North Carolina has already begun mailing ballots; Massachusetts and Washington report millions of envelopes already printed. Decentralized states including Wisconsin must coordinate across hundreds of municipalities with limited staff. A separate Republican bill introduced by Rep. Laurel Lee and Sen. Ashley Moody would require all mail ballots to arrive by Election Day, modeled on Florida’s existing deadline.

The Postal Service has stated in court filings that the rule “need not and should not prevent a single voter from voting by mail.” A White House spokesperson described the software changes as routine for bulk mailers. No public data yet shows how many ballots would be affected by the new cross-checks or batch-rejection protocol. The underlying merits of the executive order are expected to return to the Supreme Court before November.
