New Hampshire allows permitless concealed carry for people who can legally possess a firearm. The state still offers an optional Pistol/Revolver License (PRL), which many people obtain primarily for recognition/reciprocity when traveling outside New Hampshire.
Licenses are issued through local law enforcement for residents, while non-resident PRLs are issued by the New Hampshire State Police. Statute also outlines that licenses must be processed promptly and that photos/fingerprints generally are not required unless requested by the applicant.
For visitors: you generally don’t need a permit to carryin New Hampshire, but you should plan carefully for where you’re going (courthouses and federal facilities are common issues) and fortransport/storage in vehicles and shared spaces (hotels, friends’ homes). Use secure storage (locked container/safe) when you’re not in direct control of the firearm; and if you’re concerned about digital privacy or tracking of small electronics you’re traveling with, Faraday-protected SLNT bags can be a practical, discreet add-on for transport in vehicles or hotel rooms.
