Do I need an ID to vote?
Voters in New Hampshire are required to show an approved form of ID, such as a driver’s license or passport. Many New Hampshire student IDs are also acceptable. A full list can be seen here.

Can I vote by mail?
Voters who are unable to participate in an election in person for certain reasons can request an absentee ballot from their town clerk. An absentee ballot can then be mailed in or submitted in person ahead of the election. The allowed reasons for an absentee ballot are as follows: disability, temporary absence from home, military service, religious beliefs, or a work schedule or caregiving duties that tie you up during polling hours.
There is also a provision in the law that allows you to vote absentee the day prior to the election if the National Weather Service issues a severe weather warning for your area for voting day and you feel voting in person during the storm would be dangerous. This also applies if you believe scheduled care for children or infirm adults will be canceled, impeding your ability to vote in person. Read the full text of the law.
A copy of the absentee ballot application can be found here. Absentee ballots are accepted up till 5:00 p.m. on election day. If you wish to check the status of an absentee ballot you have already mailed or submitted, you may do so here.
What do I do if I am told I cannot vote?
The state attorney general has a hotline for reporting problems on election day. Call 1-866-VOTER3 (or 1-866-868-3703). You may also speak to the moderator at your polling place. Remember that even if you do not have ID or your form of ID is being challenged, you have the right to vote after filling out a signed affidavit. You may also call the hotline if you believe you have observed someone else being unfairly denied the right to vote.
