Here is a map of who honors the Washington Concealed Pistol License.
Also West Virginia, New Hampshire and Maine have Permitless Carry and Washington Residents can carry there. Do be aware that those carrying under Permitless Carry in West Virginia and Maine can't carry in all places that those with a permit to carry that those state honors. Especially Maine has many places you can carry with a permit they honor and not under Permitless Carry. Those three states though Permitless Carry don't honor all other states permit/licenses. See http://www.handgunlaw.us
