New Hampshire is a constitutional carry state, which means law-abiding adults 18 years and older who can legally possess a firearm under federal and state law may carry a concealed handgun without obtaining a permit. This extends to concealed carry within a private vehicle.
Permits
Permits are not required but may be useful for reciprocity with other states. Permits are issued by local law enforcement for qualified residents, and by the state Department of Justice for non-residents. As a constitutional carry state, New Hampshire has broad reciprocity with other states. Any person 18 and over who can legally possess a firearm may carry it concealed without a permit.
Other weapons
No other weapons are allowed to be carried concealed in New Hampshire, even with a permit.
Permitted non-lethal weapons include:
Duty to inform
There is no duty to inform in New Hampshire.
Employee parking lots
Employers in New Hampshire may not prohibit employees from storing legal weapons in locked vehicles in employer parking lots.
