Is a Maine Resident Permit Valid in Idaho?
Your Maine resident permit is valid in Idaho. The state also has permitless carry for adults 18+, so the permit mainly buys you reciprocity certainty and some federal school-zone protection.
Why
- Idaho recognizes valid carry permits from every US state.
- Idaho allows permitless carry for eligible adults 18+, which extends to visitors who may legally possess a handgun.
Idaho AG: out-of-state concealed weapons licenses are recognized ('Yes'), with the condition that 'while in Idaho, you must carry the license on your person at all times when carrying a concealed weapon' (Idaho Code 18-3302(5)(g)). No residency or permit-type restriction is stated; permitless carry independently covers US-citizen visitors 18+.

Carry rules in Idaho
Your Maine habits may not match Idaho's law. Check these three areas before you carry there.
- No proactive duty-to-inform requirement appears in the AG's official concealed-weapons guidance; carriers relying on an out-of-state license must have it with them when carrying. Cross-checked: Idaho has no must-inform statute.
- Idaho sets no state magazine-capacity limit for handguns.
- Idaho allows permitless concealed carry from age 18 for people who may legally possess a handgun, including eligible visitors.
- Anyone eligible for permitless carry (US citizen or armed forces member 18+, not disqualified) may carry a loaded concealed handgun in a vehicle without a license.
Off-limits places in Idaho
