If you’re incarcerated, on parole, or community supervision, you are NOT eligible to exercise your right vote. If you’re out of jail/prison, you’re eligible to vote but you’ll need to re-register again. You may only vote in one state and will need to be a resident of Washington.
If you were convicted in another state, you are eligible to vote as long as you’re out of jail/prison.
If you have a misdemeanor conviction or a conviction in juvenile court then you’re still eligible to vote in Washington State.
If you’re a felon and still unsure, you can call Washington State Department of Corrections (DOC) directly at: 1-800-430-9674. They will answer any specific questions you may have.
