How to Register to Vote in Washington State: Methods and Deadlines

You can register to vote in Washington State three ways: online at VoteWA.gov, by mail using a paper form, or in person at your county elections office. Online and mail applications must be received at least eight days before Election Day. In-person registration stays open all the way through 8:00 p.m. on Election Day itself.¹ Washington votes entirely by mail, so a correct registration is what gets a ballot delivered to your door.

Who Can Register

You qualify to register if you meet all four of these conditions:²

You are a United States citizen.
You will be at least 18 years old by the next election. A 17-year-old can vote in a primary or presidential primary if they’ll turn 18 by the general election.³
You have lived in Washington, in the county and precinct where you’re registering, for at least 30 days before the election.⁴
You are not currently serving a sentence of total confinement under the Department of Corrections.

Washington automatically restores voting rights the moment someone with a felony conviction leaves total confinement.⁵ There’s no court petition, no special paperwork. Whether the conviction was in Washington, another state, or federal court, eligibility returns on its own and you can register right away.

Teenagers can also get a head start. The Future Voter Program lets 16 and 17-year-olds pre-register using the same online, mail, or in-person options as any adult, and the registration activates automatically before the first election where they meet the age requirement.³

What You Need Before You Start

Have the following ready:²

Your full legal name and date of birth.
Your residential address, meaning where you physically live. A PO box doesn’t work here, because this address decides your precinct and the races on your ballot.
A separate mailing address if you get mail somewhere else.
Your Washington driver’s license number or state ID card number. If you have neither, the last four digits of your Social Security number work instead.

The form also asks your gender and whether you’ve registered before at a different address. Before you sign, read the warning on the application: knowingly providing false information on a voter registration form is a Class C felony carrying up to five years in prison and a $10,000 fine.²

Register Online

The fastest option is VoteWA.gov. You’ll enter your Washington driver’s license number, state ID card number, or the last four digits of your Social Security number, and the system checks your information against Department of Licensing records in real time.⁶ It takes a few minutes.

You may already be registered without realizing it. When you prove U.S. citizenship during certain state agency transactions, such as getting an Enhanced Driver’s License, Washington’s automatic voter registration either enrolls you or updates your existing record. Check your status at VoteWA.gov before filing a new application.

Register by Mail

Download a paper form from the Secretary of State’s website or pick one up at any county auditor’s office.⁶ Fill it out, sign it, and mail it to your county elections office or to the Office of the Secretary of State.

Two things catch people out. First, the form must be received by an elections official at least eight days before the election; a postmark alone isn’t enough.¹ Second, a missing signature is the most common reason mailed applications get rejected. Check for your signature before you seal the envelope.

Register in Person

You can register in person at your county elections office or at any voting center the county auditor has designated.¹ In-person registration remains open through 8:00 p.m. on Election Day, which makes it the fallback if you’ve missed the online and mail deadlines. You’ll receive a ballot the same day you register.⁷

Registration Deadlines at a Glance

Online: received at VoteWA.gov at least 8 days before Election Day.
By mail: received by an elections official at least 8 days before Election Day (postmark date doesn’t count).
In person: any time through 8:00 p.m. on Election Day at a county elections office or designated voting center.¹

If you’re mailing a form less than two weeks out, you’re relying on postal speed to beat the eight-day receipt deadline. Register online instead, or carry the form into your county office.

Special Situations

College Students

If you attend college in Washington, you can register at either your campus address or your home address, but not both. To use a campus address, list your dormitory name and room number as the residential address; a campus PO box doesn’t qualify.⁸ The choice determines which local races appear on your ballot. You can switch through VoteWA before the next registration deadline.

Military and Overseas Voters

Active-duty military members, their family members, and U.S. citizens living abroad can register and request a ballot through Election Day itself.⁹ Your signed ballot declaration doubles as your registration. You can apply through VoteWA, by mail, or in person, and the Federal Voting Assistance Program can help if you don’t have a Washington ID.

Tribal Land and Non-Traditional Addresses

Voters on tribal land who don’t have a standard street address can designate an identifiable location such as tribal headquarters or a PO box as their residence for registration purposes.¹⁰ The county assigns a precinct based on that location.

Address Confidentiality Program Participants

Participants in Washington’s Address Confidentiality Program, typically survivors of domestic violence, stalking, or trafficking, can register as protected records voters so their real address is used only to assign a precinct and never appears in public voter rolls.¹¹ You’ll need to apply in person or through the Address Confidentiality Program directly, with your participant authorization number alongside the standard registration information.

Updating an Existing Registration

When you move, change your name, or need to fix something on file, submit an update through VoteWA or on a new paper registration form. The deadlines are the same as for a new registration: eight days before Election Day for online and mail, through 8:00 p.m. on Election Day for in person.¹²

Because Washington mails every registered voter a ballot before each election, an outdated address is the most common reason a voter doesn’t receive one. After any move within the state, update your voter registration along with your post office change of address.

Confirming You’re Registered

Once you register, the state mails a voter registration card to your address confirming your precinct and district assignments.¹³ If it doesn’t show up within a few weeks, log in to VoteWA.gov and look up your status to confirm the application went through. If you can’t find your record, re-register before the next deadline rather than waiting to see whether a ballot arrives.
