- Is my Washington concealed carry permit honored in Idaho?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Idaho's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/ID/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
