On Aug. 24, Slay News described the rule as “sweeping voter eligibility verification” for mail ballots.

The USPS final rule says states retain full control over who may vote by mail. USPS “will not second-guess the states’ submissions.”

The rule requires authorized state users to submit:

  • The recipient’s name and envelope address.
  • The issuing state.
  • Intelligent Mail barcodes for the outbound and return envelopes.

Those are submitted data fields. They are not facts certified by USPS. The agency checks whether the required data were supplied and whether covered mail complies with mailpiece-design and data-reporting standards.

The rule says this plainly: “The Postal Service is not verifying addresses, names, voter eligibility, or citizenship status as part of this verification process.”

It also says birthdates, Social Security numbers and other voter-registration details will not be uploaded. It does not authorize USPS to inspect completed ballots, determine an individual voter’s eligibility or audit state voter rolls. Its review “focuses exclusively on exterior mailpiece criteria and barcode scan data.”

Here is the arrangement in its natural habitat:

STATE: Decides who may vote.
STATE: Prepares ballot mail and submits specified data.
USPS: Checks submission, mailpiece and barcode-reporting compliance.
USPS: Does not establish that a submitted name or address is accurate.
USPS: Does not become the state.

USPS may return noncompliant batches of outbound ballot mail to election officials. So the rule can have consequences. “It only concerns envelopes” does not mean nothing can happen. It means the Postal Service’s authority concerns mail compliance, not voter eligibility.

The federal government made the same distinction in an August 24 Supreme Court filing. The solicitor general said USPS “will not perform any verification of voter eligibility” and will not refuse to carry ballots merely because a voter was absent from a state-submitted list. That is the government’s litigation position. It is not a judicial ruling.

The rule covers specified outbound ballot mail for federal general, special and runoff elections. It does not cover primaries or elections involving only state offices. Military and overseas ballots must be segregated from covered outbound mail.

Its operation in 2026 also remains unsettled. USPS says it will not implement the rule specifically for that election unless the federal government obtains relief from outstanding injunctions. MS NOW reported the administration’s position in similar terms.

The documents do not resolve whether the rule is constitutional, how burdensome it may prove, whether its data practices are adequately secure or how the litigation will end.

They do resolve one narrower matter.

Determining who may vote is one job. Checking whether ballot-mail batches meet submission, envelope and barcode requirements is another. The headline announced the first. The rule describes the second.
