Mail-in Voting Envelopes Don’t Reveal Party During General Election

Quick Take

Facebook posts falsely suggest that envelopes used for mail-in ballots in general elections reveal party affiliation, saying postal workers may “toss” votes. Voting experts say they don’t know of any such labels in general elections — only on envelopes during primary elections.

Full Story

Some states have made it easier to vote by mail, particularly in recent months because of health risks from the COVID-19 pandemic, as we’ve written.

But, as we’ve reported, President Donald Trump has attacked mail-in voting as “fraudulent” and “corrupt,” though voting experts have said his claims are exaggerated or false.

A video post shared on Facebook amplifies false claims about the security of mail-in voting by showing ballot envelopes with bar codes that include the letters “D” and “R” — designating Democrat or Republican. The narrator on the video says that a postal worker can “toss” the ballot after seeing the party affiliation, and she warns: “Do not vote by mail.”

Another post shows a screengrab from the video, with a finger pointing to the bar code, and the headline: “THE POST OFFICE KNOWS WHICH BALLOTS ARE DEM VS REP.”

But the Facebook posts don’t explain that the envelopes shown in the video are from Florida’s Aug. 18 closed primary, during which voters could vote only for members of their own party.

In a general election, ballot envelopes in Florida do not reveal party affiliation, an election official told us. Voting experts told us they aren’t aware of any jurisdiction using such labels in general elections, nor would there be a reason to do so.

The office of the supervisor of elections for Palm Beach County, Florida — where the envelopes in the Facebook posts were sent — confirmed that in a statement to In a closed primary, “voters are sent ballots according to their precinct and their party affiliation. The ballots in that video are primary ballots.” The alphanumeric codes on the envelopes shown in the video are used to direct the ballots for counting.

“The alternative would be to open the envelope and look at the ballot itself to ensure that the voter voted the proper party and precinct style. We want to maintain ballot confidentiality, so those numbers are on the outside,” the statement said. “It would be a federal crime for any post office employee to tamper with this process and we have received no such reports of anything like this happening.”

The statement from the supervisor’s office, portions of which were shared on Twitter, noted, “All ballots for the general election in November will look exactly the same, as voters can vote for whoever they would like. There would be no way to tell the party affiliation of a voter based on their vote-by-mail envelope for the general election.”

We contacted county election officials in other states to see if the same was true elsewhere. Officials in Los Angeles and Philadelphia told us that party designations do not appear on mail-in ballot envelopes for general elections in those counties.

Matthew Weil, director of the Elections Project at the Bipartisan Policy Center, said that state laws determine what appears on ballot envelopes, though counties have some control over the design of the ballot materials. But party affiliation should not appear on envelopes in any general elections, he told us in a phone interview.

Justin Levitt, an election law professor at Loyola Marymount University, told us in an email that the Facebook video is “misleading to the extent it implies anything about the general election.”

“I don’t know of any election official in the country who indicates the voter’s party affiliation in the bar code (or on the envelope) for the general election. For a primary, it serves an administrative double-checking purpose (you can confirm with a quick scan that Democratic primary ballots are going to Democratic primary voters, etc.). But it doesn’t serve any similar purpose in the general election,” Levitt said.

“In a general election, there’s no reason at all to have party affiliation listed on the exterior of a mail ballot, and I don’t know of anywhere where that happens,” he said.
