Is a Idaho Non-Resident Permit Valid in Colorado?

Why

• Colorado's official reciprocity list includes Idaho.
• The agreement covers only permits issued to Idaho residents.
• A non-resident permit from Idaho therefore does not qualify — the holder is not an Idaho resident.

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

Carry law is state law. From the moment you enter Colorado, these rules replace the ones you know from Idaho.

• 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.
