Is a Wyoming Resident Permit Valid in Colorado?

Why

• Colorado's official reciprocity list includes Wyoming.
• The agreement covers only permits issued to Wyoming residents.
• Colorado honors out-of-state permits only for holders 21 and older, and Wyoming issues this permit from age 18.

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

Crossing into Colorado swaps the rulebook. Here is what changes for a visiting carrier.

• 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

Colorado bans carry in 6 kinds of places. The first on the list:

• K-12 public school grounds (permittee's handgun may remain in a locked vehicle)
• Public buildings with permanent security screening and guards at each entrance

Wyoming vs Colorado: what changes at the state line

Crossing from Wyoming into Colorado changes 3 rules: permitless carry (Yes (18+) → No); magazine limit (None → 15 rounds); out-of-state permits honored (35 states → 34 states).

Going the other way, a Colorado resident permit in Wyoming: recognized — and permitless carry applies.

Frequently asked questions

Does Colorado honor a Wyoming non-resident permit?

Wyoming does not issue non-resident carry permits (Residents only — the DCI FAQ answers 'Can a non-resident obtain a concealed firearm permit in Wyoming?' with 'No.' Active-duty Wyoming military stationed out of state may still apply; a permit remains valid if the holder later moves away but cannot be renewed), so the question does not arise.

Can a Colorado resident permit holder carry in Wyoming?

Recognized — and permitless carry applies. Reciprocity is decided by the destination state, so the answer in this direction depends on Wyoming'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.
