Do poll-worker markings disqualify your ballot?

A free brief from an independent research desk. Question: does a poll worker's mark void your ballot? Build: AP Fact Check (15 Oct 2026), the North Carolina State Board of Elections (14 Oct 2026), the Illinois State Board of Elections, the Tennessee Secretary of State, and the Snopes fact check, plus the statutes those agencies cite.

The claim

Posts circulating as early voting opened for the 3 November 2026 US midterms warn that if a poll worker writes on your ballot it is void, listing “a letter, a checkmark, a star, an R or a D … any writing of any kind.” The message ends: “Please forward this to everyone you know.”

Short answer

No. Election officials in multiple states say a poll worker's mark does not disqualify a ballot. In several states, poll workers are required by law to write on ballots. This same copy-paste warning circulated before the 2020 and 2024 elections and was answered the same way then.

Where the marks actually come from

North Carolina: state law assigns each by-mail and early ballot a retrievable number (N.C.G.S. § 163-166.45), and in some counties the voter's precinct is written on early ballots so they can be sorted after the election (N.C.G.S. § 163-132.5G). The State Board, 14 Oct 2026: “Election workers write on ballots for different reasons as required by law. This in no way affects whether your ballot will be counted.”
Illinois: “Under Illinois law, election judges must initial ballots before issuing them to voters,” the State Board of Elections wrote. “These initials are an important safeguard and will NOT disqualify your ballot.” The provision requiring a judge's initials is Section 17-9 of the Election Code (10 ILCS 5/17-9).
Tennessee: “In Tennessee, a ballot is not disqualified simply because an election official or poll worker makes an administrative notation on it,” Secretary of State Tre Hargett said.
Other states whose law requires poll workers to mark ballots, per Snopes' survey: Minnesota, Missouri and Texas.

The real rule behind the rumor

There is a real rule, but it points at the voter, not the poll worker. Rules about marks usually concern identifying marks made by the voter. What stops a ballot is not a stray mark; per the North Carolina State Board, it is damage that affects “the bars on the margins of the ballot” or “the selection ovals.” The tabulator reads the ovals and timing bars, so a mark elsewhere does not change a selection. As former US Election Assistance Commission chairman Ben Hovland put it: “A stray mark is unlikely to do that and there are other safeguards to ensure the voter's intent is reflected.”

What I could not verify

No US state was found disqualifying ballots merely for poll-worker markings. The strongest available statement is Snopes' — that it could find no such case “unless it renders the voter's selections unreadable.” That is a negative finding from a survey, not a line-by-line reading of all 50 states' canvassing rules.
I could not retrieve the full official text of 10 ILCS 5/17-9: the Illinois General Assembly site returned an error at the time of writing. The Illinois requirement rests here on the state board's own fact check and an independent statute reference; treat the exact statutory wording as unread.

What to do

If a poll worker marks your ballot and you want to know why, ask. Their marks are administrative and in many states mandatory. Do not add identifying marks of your own.
