Primary elections
Massachusetts 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
Massachusetts 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: Seventeen days before election for state biennial elections; 10 days before election for presidential or state primaries. Ends: Two business days before an election. Locations and hours are set locally.
Voting by mail
Any Massachusetts voter can request an absentee/mail ballot. No excuse is needed.
Your local election office
In Massachusetts, many elections are run by your city or town clerk rather than the county. Find contact information for your local election office on Massachusetts’s official election website.
