Voter Registration and Eligibility

Voting in the United States begins with meeting eligibility requirements and completing the voter registration process. To participate in federal, state, and local elections, you generally must be a U.S. citizen, at least 18 years old by Election Day, and meet your state’s residency rules. While every state except North Dakota requires registration, the specific procedures and deadlines vary. Understanding how voter registration works is essential to ensure you are ready to vote.

Eligibility Requirements

To be eligible to vote, you must be a U.S. citizen and meet your state’s residency and age requirements. Many states allow voters to pre-register at age 16 or 17 if they will be 18 by Election Day. Some states restrict voting rights for individuals with felony convictions until rights are restored. Residency requirements typically include living in your state and county for a specified period, often 30 days. Even if you are homeless, you can still meet residency criteria by identifying a fixed location for voting purposes.

The Registration Process

Voter registration usually occurs at the local level and can be completed online, by mail, or in person at locations like DMV offices or libraries. Registration deadlines vary, but 25 states and Washington, D.C. offer same-day registration, allowing you to register and vote on Election Day. Identification requirements differ by state and may include a driver’s license, state ID, or other documents.

Updating Registration After Moving

If you move, updating your voter registration is necessary to vote from your new address. Many states require this, even within the same county. Our state-by-state guide explains how to update your registration and when re-registration might be needed for changes like name or party affiliation.

Ballots and Voter ID Laws

Once registered, voters must understand rules about ballots and identification. Some states require voters to show ID at the polls, while others have more lenient policies. If there are questions about your registration, you may be allowed to cast a provisional ballot. Primary election voting rules may differ, often requiring party affiliation, explained in Primary Elections: Who Can Vote and Why.
