Colorado to Wyoming: common questions
- Do the laws change when you drive from Colorado to Wyoming?

- Is my Colorado concealed carry permit honored in Wyoming?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Wyoming's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/WY/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
- How current is this Colorado to Wyoming comparison?
- Every rule on this page stores the date it was last checked against its source; the oldest on this comparison is 2026-06-07.
