A Federal Postal Rule Could Change How Kentucky Mail Absentee Ballots Are Handled

A new USPS proposal would require voter names and ballot-envelope barcode data for federal mail ballots, raising practical questions for Kentucky’s county clerks before the 2026 general election.

The U.S. Postal Service has proposed a new federal rule for ballot mail.

The proposal, released after President Trump’s March 31 executive order on federal elections, would require state election officials or their authorized mail-service providers to give USPS a list of voters receiving mail-in or absentee ballots for federal elections, along with unique barcode information tied to each ballot envelope. USPS would then use that information to verify ballot mail before accepting it into the mailstream.

Kentucky does not have universal mail voting. State law limits absentee voting by mail to people who qualify for specific reasons, including age, illness, disability, military service, temporary absence, student residency, pretrial detention, or being away from the county on in-person voting days.

That means the proposed USPS rule would not affect every Kentucky voter. It would affect a smaller group of voters who often have less flexibility if a ballot is delayed, rejected, or sent through a new verification step.

If this rule is finalized, what would Kentucky’s Secretary of State, State Board of Elections, county clerks, ballot vendors, and mail-service providers have to do before a lawful mail absentee ballot can be sent and returned?

That is the part Kentucky voters should understand now, before the rule becomes final.

What USPS wants to require

On March 31, 2026, President Donald Trump signed Executive Order 14399, titled “Ensuring Citizenship Verification and Integrity in Federal Elections.” The order directs federal agencies to take a larger role in voter eligibility information, citizenship data, ballot mail procedures, and election-related enforcement.

The order tells the Department of Homeland Security, through U.S. Citizenship and Immigration Services and in coordination with the Social Security Administration, to compile and transmit a “State Citizenship List” to each state’s chief election official. The order says that the list should identify people confirmed as U.S. citizens, over 18 by the relevant federal election, and residing in the state.

The order also directs the U.S. Postal Service to begin rulemaking on ballot mail. That is the part now moving from a White House directive into an agency proposal.

On May 29, Reuters reported that USPS had proposed a rule requiring states to submit lists of voters receiving mail-in ballots, including voter names and unique barcodes associated with each ballot. Reuters also reported that the proposal excludes primary elections, applies to federal elections, and is open for public comment for 30 days before it can be finalized.

The proposed USPS rule says it is acting pursuant to Executive Order 14399. It would amend the Domestic Mail Manual, the postal rulebook that governs how mail is prepared and accepted. The proposal would require unique serialized Intelligent Mail barcodes on outbound and return ballot envelopes, create a “Mail-In and Absentee Participation List,” and require states or authorized election officials to submit voter names and barcode data through a new federal ballot-mail process.

That is the development. The president issued the order in March. USPS has now begun the agency rulemaking needed to implement the ballot-mail portion.

Kentucky already has a limited mail absentee process

Kentucky’s mail absentee process already has state rules.

Under KRS 117.085, most requests for a mail-in absentee ballot must go through a secure online portal established by the Kentucky State Board of Elections. The voter must provide personally identifiable information for verification. If the voter qualifies, the portal sends the request to the county clerk in the county where the voter is registered.

The county clerk then issues the ballot, two official return envelopes, and voting instructions. Kentucky law also sets timing rules. The portal cannot open more than 45 days before an election and closes 14 days before the election. County clerks must transmit eligible mail-in absentee ballots within four days of receiving the request or of ballots becoming available.

Kentucky already uses ballot labels and barcodes in its absentee process. The important difference is that the USPS proposal appears to add a federal postal verification layer tied to ballot-envelope identifiers and a federal participation list.

That could require the state, county clerks, or their vendors to transmit voter and barcode data to USPS before federal election ballots are accepted for mailing.

The proposed rule also points toward a new Privacy Act record notice. That matters because voter names and ballot-envelope barcode data would not merely stay in a county clerk’s office or state election portal. USPS would create a federal data record tied to ballot mail. The details of that record, including who can access it, how long it is kept, and whether it can be shared with enforcement agencies, still need to be examined once the notice is published.

The executive order assigns enforcement roles to the Department of Justice. It directs the Attorney General to prioritize investigations and prosecutions involving individuals who allegedly assist ineligible voters in participating in federal elections or in distributing ballots to ineligible voters. It also directs agencies to consider steps to withhold federal funds from states or localities that fail to comply, where federal law allows.

Those provisions are why this cannot be treated as a routine postal update. USPS is the agency drafting the ballot-mail rule, but the White House order also brings DHS, USCIS, SSA, DOJ, state election officials, county clerks, and election vendors under the same federal election directive.

The voters most likely to feel delays

Kentucky voters do not vote primarily by mail. Most Kentuckians vote in person on Election Day, during no-excuse early voting, or through excused in-person absentee voting. The Kentucky absentee portal for the 2026 primary was open from April 4 through May 5, with excused in-person absentee voting, no-excuse early voting, and Election Day voting listed as the three voting methods.

That limited use of absentee mail voting may make this issue seem smaller here than in states that mail ballots to most voters.

Kentucky’s mail absentee voters are often the people least able to absorb confusion or delay.

A disabled voter may depend on mail voting because getting to the polls is not realistic. A college student may be outside the county where they are registered. A pretrial detainee may still have the right to vote but may not be able to walk into a polling place. A voter receiving medical treatment outside the county may need a ballot sent to an address other than their usual residential address.

For those voters, an added data-match or barcode-verification step is not an abstract policy change. It could affect when a ballot is mailed, whether a ballot packet is accepted by USPS, how a county clerk troubleshoots a missing ballot, and how much time a voter has left to correct a problem before Election Day.

Kentucky county clerks would likely carry much of the operational burden. They already issue absentee ballots by mail after a voter qualifies under state law. If USPS requires a participation list and barcode data, clerks and election vendors would need clear instructions on ballot-envelope design, data formatting, transmission deadlines, rejected mail pieces, replacement ballots, and voter notification.

The Kentucky State Board of Elections also has a central role. The Board operates under KRS Chapter 117 and maintains the statewide absentee portal. The Board consists of Secretary of State Michael G. Adams, who serves as chief election official, and eight appointed members.

If the federal rule is finalized, the State Board and Secretary Adams will have to decide how Kentucky responds. They may need to issue guidance to county clerks, comment on the USPS rule, coordinate with ballot vendors, evaluate litigation risk, and explain to voters whether Kentucky’s mail absentee process will change before the November 2026 general election.

The legal fight is still unresolved

The legality of the executive order is already being challenged.

A federal judge in Washington, D.C., Judge Carl Nichols, declined to block the order for now. The Associated Press reported that Nichols found the request premature because the challenged provisions had not yet taken immediate effect. The ruling did not decide that the order is lawful. It left room for renewed challenges if implementation proceeds.

Democratic Party entities and civil rights groups appealed that decision. Reuters reported on June 2 that plaintiffs had asked the D.C. Circuit to intervene.

A separate set of lawsuits is pending in Boston before U.S. District Judge Indira Talwani. Reuters reported that Democratic-led states and voting-rights groups are asking that court to block the order. Their argument is that the Constitution gives election-rule authority to states and Congress, not the president.

The Brennan Center, which represents voting-rights plaintiffs in the Massachusetts case, describes the order as an attempt to impose nationwide changes to mail voting through executive action. The group argues that the president lacks the authority to override state mail-voting laws by directing USPS to reject ballots outside a federally approved process.

The court calendar and the USPS rulemaking calendar are now running simultaneously.

If courts block the order, Kentucky may not have to implement the proposed postal requirements. If courts do not block it before USPS finalizes the rule, Kentucky election offices may have to prepare for changes while litigation continues.

Share this with a Kentucky voter

What you can do

Kentuckians do not have to wait until November to ask practical questions.

Submit public comments to USPS during the comment period. The strongest comments will not be generic statements of support or opposition. They should identify operational problems: what happens if a barcode file is wrong, who tells the voter, how quickly a replacement ballot can be mailed, how disabled voters are protected, what data USPS stores, and whether county clerks can meet Kentucky’s existing deadlines.

Ask Secretary of State Michael Adams and the Kentucky State Board of Elections whether Kentucky will comment on the USPS proposal. Kentucky’s election officials should say whether the proposed rule conflicts with KRS 117.085, whether county clerks would need new guidance, and whether any voter data would be sent to USPS.

Ask your county clerk what the office has been told so far. The useful questions are narrow: Have clerks received guidance from the State Board? Would ballot-envelope design change? Would the county need vendor changes? How would voters be notified if USPS rejects a ballot-mail packet? What is the backup plan if litigation changes the rules close to Election Day?

Track the court cases. The D.C. appeal and the Boston litigation could determine whether the federal order reaches local election offices before the 2026 general election. A ruling that blocks the order would change the immediate risk. A ruling that allows implementation would increase the need for Kentucky-specific guidance.

Share accurate information with anyone who may need to vote absentee this year.

Kentucky’s mail absentee voters should not have to navigate federal rulemaking to cast a lawful ballot.

They need clear dates, clear eligibility rules, clear county contacts, and early reminders to request ballots when the state portal opens.

The core issue for Kentucky is this: a federal postal rule could alter the steps between a lawful mail absentee request and a ballot arriving in a voter’s hands. That change would involve USPS, federal data, state election officials, county clerks, and voters who often have the least margin for delay.
