Registering to vote

Primary elections

New Hampshire 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

New Hampshire requires a photo ID to vote in person. If you don’t have acceptable ID, you can vote a provisional ballot, but you must take extra steps after Election Day (such as showing ID at the election office) for it to count.

Early voting

New Hampshire does not offer early in-person voting to all voters. Voters who qualify for an absentee ballot may be able to vote it in person before Election Day.

Voting by mail

New Hampshire requires an approved reason (excuse) to vote by absentee/mail ballot. Check the state’s list of qualifying reasons.

Your local election office

In New Hampshire, many elections are run by your city or town clerk rather than the county. Find contact information for your local election office on New Hampshire’s official election website.
