USPS Implements Rule Requiring States to Provide Voter Lists for Mail-in Ballots

The United States Postal Service (USPS) published a rule on August 22, 2026, requiring states to provide lists of voters who received mail-in ballots. This rule aligns with an executive order issued by President Donald Trump on March 31, which mandates that states notify USPS at least 90 days before an election and submit a list of eligible voters for mail-in ballots at least 60 days prior to the election. The rule states that individuals must be enrolled with USPS to be included on the state's Mail-In and Absentee Participation List, and states must submit the individual's name, address, and a uniquely serialized Intelligent Mail barcode (IMb) on both the outbound and return ballots. However, the rule cannot take effect due to an existing federal injunction against Trump's executive order, issued by U.S. District Court Judge Indira Talwani, who ruled that certain sections of the order were unconstitutional. The injunction was renewed in July, preventing USPS from enacting the rule until the court lifts the injunction. The Trump administration has argued that the judicial review is premature, stating that plaintiffs cannot demonstrate harm until the rule takes effect. USPS Postmaster General David Steiner defended the rule, emphasizing the importance of matching ballots sent by states with those actually dispatched. A White House spokesperson reiterated the administration's commitment to ensuring the safety and security of elections.
