New Hampshire residents who will be 18 years of age or older on election day, and a United States citizen, may register to vote. 17-year-olds who will be 18 by the date of the next scheduled election may register to vote, but may not actually vote until they are 18.

In New Hampshire eligible citizens with felony convictions may register when they are released from incarceration, even if they are still on parole or probation. Eligible citizens awaiting sentencing or serving jail sentences for misdemeanor charges may register to vote absentee from the town where they last lived.

New Hampshire citizens who are homeless may register using as their address the social service agencies where they get their mail, or the shelter where they are living.

New Hampshire has no length of residency requirement for voting. Even if you moved here recently, you may vote if this is the place where you are living now.

You cannot register or vote in any town in New Hampshire if you are just vacationing or visiting that town.

No. You may claim only one place as the place you live for voting purposes. Generally it is the place where you live most of the year.

If you moved to a new town or or to a different ward in your city, or if you never registered in your town before, you need to register in order to vote.

If it has been many years since you last voted, you probably need to register again. The voting rolls are “purged” of non-voters about every 10 years.

You can find out whether you are registered and with which party you are registered via the Secretary of State’s website.

If you are already registered in the town or in the ward of the city where you live now, you don’t need to register again.

If possible, register in advance at your town or city clerk’s office, up to 6-13 days before an election (this 6-13 days period when no registrations are accepted will vary depending on specific elections–check with town/city clerk’s office).

NH law allows voters to register on election day, at their own polling place. Be aware this will take extra time at the polls. Bring documents to prove identity, age, citizenship, and where you live to speed up the process. NOTE: Effective in 2025, per HB 1569 passed last year, anyone registering in advance or at the polls on election day for the first time in New Hampshire MUST show a photo ID and papers to prove citizenship and where you live. Ask for more information from the registrars if this applies to you.

If you wish to run for public office, you must be a registered voter in that party before the filing period opens.

You have three choices:

1. Apply at your town or city clerk’s office. You will be required to fill out a voter registration form and will be asked to show proof of identity, age, citizenship and where you live.

2. Register with your city or town”s Supervisors of the Checklist. By law they are required to meet about 6 to 13 days before each election (the exact date will vary by elections and by towns). Check the local newspaper or call your city/town clerk’s office for the place, date and time of such meeting. You will be required to fill out a voter registration form and will be asked to show proof of identity, age, citizenship and where you live.

3. You may register to vote at the polling place on election day at all elections. You will be required to fill out a voter registration form and will be asked to show proof of identity, age, citizenship and where you live.

New Hampshire does not have online voter registration. Nor does it allow third-party registrations.

If you meet the state’s voter qualifications and are unable to register in person because of health issues, disability or temporary absence, which includes incarceration for a misdemeanor or awaiting trial, you may register by mail.

You should request an absentee voter registration affidavit, New Hampshire voter registration form, and instructions from your town or city clerk. You must return the completed affidavit, voter registration form, and copies of documents proving identity, age, citizenship, and where you live to your town or city clerk. Your affidavit will need to be witnessed (but not notarized.)

When you register, you will fill out a form giving your name, age, place of birth, local residence, previous voting address if you were registered to vote somewhere else, and a driver’s license identification number or the last four digits of your social security number if you don’t have a license. You will be asked to read and sign a statement saying you understand voting fraud is a crime.

You will also be asked for documents to prove your identity, age, citizenship, and where you live in the voting district.

A driver’s license with your current address can be offered for identity, age, and where you live.

A birth certificate (if you have not since changed your name) or naturalization papers or US Passport can prove citizenship.

Government mail sent to your address can prove where you live. A lease or deed or utility bill can also prove where you live.

College students can show documents proving their campus or off-campus addresses, either in paper copies or online.

If you don’t have all the required documents, don’t worry. You may sign a paper attesting to the truth of the information you provide.

NOTE: Effective in 2025, per HB 1569 passed last year, anyone registering at the polls on election day for the first time in New Hampshire MUST show a photo ID and proof of age, citizenship, and where you live. Ask for more information from the registrars if this applies to you.

Note: to register you must show photo ID plus documents showing your age, where you live, and citizenship. A driver’s license with your current address plus a passport or birth certificate or naturalization papers will prove these 4 requirements.

SB1569, passed in 2024, gives little option to people without these documents. It takes effect AFTER the November 2024 election. Consult the Secretary of State for guidance.

You may register with a specific party, or you may leave party affiliation blank on the registration form. It is your choice. In New Hampshire we use the term “undeclared” for voters with no party affiliation.

In the next primary, if you registered with a party, you will be given a ballot for that party. If you did not register with a party, you may ask for a ballot for the party of your choice.

Yes. However, you may change back to “undeclared” at a special table before you leave the polling place. Or you may change your party at your town clerk’s office or a supervisors of the checklist meeting up to about 3 months before the next primary election.
