Is a Maine Resident Permit Valid in Colorado?

Why

• Maine is not on Colorado's official reciprocity list.

Colorado honors a permit only if the issuing state honors Colorado's CHP, the holder is 21+, is a RESIDENT of the issuing state, and carries a matching driver's license or state ID from that state. Colorado explicitly does not recognize any permit issued to a non-resident of the issuing state - a Colorado resident also cannot carry in-state on another state's non-resident permit (C.R.S. 18-12-213; CBI reciprocity page).

Carry rules in Colorado

Your Maine habits may not match Colorado's law. Check these three areas before you carry there.

• No duty to volunteer. Permittee must carry the permit plus valid photo ID whenever carrying and must produce both upon demand by a law enforcement officer; failure is a class 1 petty offense (C.R.S. 18-12-204(2)(a)).
• Colorado limits magazine capacity to 15 rounds — a limit that applies to visitors, and one of the easiest laws to break by accident.
• Colorado is not a permitless-carry state: concealed carry there requires a permit Colorado recognizes.
• A person who may lawfully possess a handgun may carry it, loaded, in a private automobile without any permit for a legal use including self-defense (C.R.S. 18-12-204(3)(a)); this does not extend onto school grounds under 18-12-105.5.

Off-limits places in Colorado

Maine vs Colorado: what changes at the state line

Crossing from Maine into Colorado changes 3 rules: permitless carry (Yes (21+) → No); magazine limit (None → 15 rounds); out-of-state permits honored (23 states → 34 states).

Going the other way, a Colorado resident permit in Maine: permit not recognized — but permitless carry applies.

Frequently asked questions

Does Colorado honor a Maine non-resident permit?

Not recognized. The answer is the same as for the resident permit on this page.

Can a Colorado resident permit holder carry in Maine?

Permit not recognized — but permitless carry applies. Reciprocity is decided by the destination state, so the answer in this direction depends on Maine's law, not Colorado's.

Where does Colorado publish its official reciprocity list?

Colorado publishes its recognition policy on an official state page, linked in the sources on this page. That page is the authority — check it shortly before travel, because recognition lists change without much notice.
