Registering to vote

- By mail: must be received 21 days before Election Day.
- In person: available through Election Day (same-day registration).

Primary elections
Maine has semi-closed primaries: voters registered with a party vote in that party’s primary, and unaffiliated voters may choose one party’s primary.
Voter ID
Maine does not require most voters to show an ID document to vote in person; election workers confirm identity in other ways, such as checking a signature or personal information. First-time voters who registered by mail may need to show ID under federal law.
Early voting
Starts: Thirty days before the election (in-person absentee). Ends: Three business days before election, unless the voter has an acceptable excuse. Locations and hours are set locally.
Voting by mail
Any Maine voter can request an absentee/mail ballot. No excuse is needed.
Your local election office
In Maine, many elections are run by your city or town clerk rather than the county. Find contact information for your local election office on Maine’s official election website.
