How to register to vote in the 2026 US midterms: Deadlines, ID rules and what to know state by state

More than 11 million Americans had already voted in the 2026 US midterm elections by October 20, but registration deadlines have passed in several states, leaving eligible voters with limited options to participate in the November 3 election. Registration rules, early voting schedules and mail-in ballot requirements differ across states, making it essential for voters to check local election rules before casting their ballots.

According to the University of Florida Election Lab’s early vote tracker, more than 3 million Americans had voted in person before Election Day, while more than 7 million had submitted mail-in ballots as of October 20.

The midterm elections will decide the balance of power in Congress, with all 435 seats in the House of Representatives, 33 Senate seats and 39 governorships up for election. Early voting has become an important part of the campaign, with Democrats showing a higher early-voting rate than Republicans, according to NBC News. As of Tuesday, around 51% of registered Democrats had voted early, compared with 32% of registered Republicans and 17% of voters identified as others.

Since individual states administer federal elections, Americans must follow state-specific rules governing voter registration, identification, early voting and absentee ballots.

2026 voter registration deadlines by state

Voter registration deadlines vary across the country. While some states require voters to register weeks before Election Day, others allow eligible residents to register and vote on the same day.

Twenty-four states and Washington, D.C., permit same-day voter registration during early voting, on Election Day or both. Of these, 17 allow voters to register throughout the early voting period as well as on Election Day.

California, for instance, had a regular voter registration deadline of October 19. However, eligible residents who missed it can still register in person during the early voting period, from October 24 to November 2, and on Election Day, November 3.

In contrast, registration deadlines for this election have passed in several states, including Alabama, Florida, Mississippi, Ohio, South Carolina, Texas and West Virginia. Voters who have not registered in these states generally cannot participate in the 2026 election.

North Dakota is an exception because it does not require voter registration. Eligible voters must instead present valid state identification at the polls.

The following deadlines and early voting periods are among those listed for the 2026 midterms:

State	Voter registration deadline	Early voting dates
Alabama	October 19	No early voting
Alaska	October 4	October 19-November 2
Arizona	October 5	October 7-October 30
Arkansas	October 5	October 19-November 2
California	October 19; November 3 in person	October 24-November 2
Colorado	October 26; November 3 in person	October 19-November 2
Connecticut	October 16; November 3 in person	October 19-November 1
Delaware	October 10	October 22-November 1
District of Columbia	October 13, by receipt; November 3 in person	October 26-November 1
Florida	October 5	October 24-October 31
Georgia	October 5	October 13-October 30

The applicable registration method matters because deadlines can differ for online, mail-in and in-person applications. Voters should consult their state or local election office to confirm eligibility, registration status and the rules that apply to their address.

What ID do you need to vote in the 2026 Midterms?

Identification requirements vary by state, so there is no single document that every American voter must carry to the polls. Voters should check their state election authority's official guidance to establish which forms of identification are accepted and whether additional documentation is required.

North Dakota, which does not require voter registration, requires voters to present valid state identification at polling locations.

Voters should also verify their designated polling location and its operating hours before travelling to vote. State and local election websites provide information about polling places, identification requirements and early voting locations.

How to Vote in the 2026 Midterm Elections: Early voting rules

Early in-person voting allows eligible Americans to cast their ballots at designated voting sites before November 3. Forty-seven states and Washington, D.C., offer early voting, although the dates and availability vary by jurisdiction.

Most early voting periods end before November 2. Alabama, Mississippi and New Hampshire do not offer no-excuse early in-person voting, according to Ballotpedia.

Voters planning to cast their ballots early should check their local election office's website for the location and operating hours of designated voting sites. Although ballots may be scanned as they are cast, results are generally not tallied until polls close on Election Day.

Mail-in ballot deadlines and absentee voting rules

Americans who prefer not to vote in person can use mail-in or absentee ballots, subject to their state's eligibility and application rules. Depending on the state, voters may request a ballot online, by mail or in person. Some jurisdictions also allow voters to sign up for a permanent mail-in ballot list.

Eight states and Washington, D.C., conduct elections entirely by mail: California, Colorado, Hawaii, Nevada, Oregon, Utah, Vermont and Washington. Residents in these jurisdictions generally receive ballots automatically rather than having to request one.

In 13 states, voters must provide a valid excuse to qualify for an absentee ballot. The other 29 states allow absentee voting without requiring an excuse.

Federal law requires absentee ballots to be sent to active-duty military personnel and overseas voters at least 45 days before a federal election. Completed ballots must be postmarked on or before Election Day, although state-specific rules determine the deadlines and conditions for counting them.

Voters should confirm whether their state requires ballots to be received by Election Day or permits postmarked ballots to arrive later. They should also check the official instructions for ballot drop-off locations and return procedures.

Most states offer online ballot-tracking services that allow voters to check whether their ballots have been received and processed. These services are generally accessible through official state election websites.
