USPS mail-in ballot rules would create new federal verification steps before states send ballots through the postal system. The rules remain blocked by federal court injunctions and cannot yet affect the 2026 midterms, as reports the Baltimore Chronicle.
Primary source: U.S. Postal Service final rule filed for publication in the Federal Register.
What changes under the new USPS mail-in ballot rules
The Postal Service would require states to submit voter information through a new Federal Ballot Mail Portal.
The data would include a voter’s name, address and unique Intelligent Mail barcode. Birthdates and Social Security numbers would not be uploaded.
Before outgoing federal ballots enter the postal network, USPS would verify their barcodes against portal records.
The main requirements include:
- unique barcodes for federal ballot envelopes;
- voter names and addresses submitted to the federal portal;
- state certification of ballot-mail preparation;
- USPS verification before accepting outgoing ballot batches.
States could update their submissions until their final lawful ballot-mailing date. The rule generally seeks initial data around 30 days before elections.
USPS says the system tracks ballot mail, not voter eligibility or individual voting choices.
Could USPS reject mail-in ballots?
Under the final rule, USPS could refuse outgoing federal ballot mailings that fail verification requirements. It would not decide whether individual voters are legally eligible.
| Issue | What the rule would do |
|---|---|
| Voter data | collect name, address and ballot barcode |
| Eligibility | remain controlled by state election authorities |
| Ballot contents | remain inaccessible to USPS |
| Enforcement | blocked while injunctions remain |
USPS also says it will not open ballots or know how voters voted. State officials would continue deciding which ballots qualify for counting.
That distinction is central to the legal fight. Critics argue federal collection of voter information reaches into elections traditionally administered by states.
When could the USPS ballot rules take effect?
The final rule lists an effective date of August 21, 2026. However, USPS explicitly says it will not implement it for 2026 while injunctions remain.
The agency says implementation could begin quickly if courts provide relief before ballots are mailed.
The rule is scheduled for Federal Register publication on August 26. USPS received more than 200,000 public comments during rulemaking.
For voters, nothing changes immediately. Existing state rules and current USPS election-mail procedures remain operative while litigation continues.
