Residency requirements

To register to vote in Washington, you must be a resident of the state. State law does not specify a length of time for which you must have been a resident to be eligible.

On November 7, 2023, the Washington State Alliance for Retired Americans filed a lawsuit in the United States District Court for the Western District of Washington challenging a provision in the state constitution that requires voters to live in the state for at least 30 days before Election Day. In March 2024, a federal judge approved a consent decree, with the state of Washington agreeing not to enforce the provision.

Verification of citizenship

See also: Laws permitting noncitizens to vote in the United States

Washington does not require proof of citizenship for voter registration. An individual must attest that they are a U.S. citizen when registering to vote. According to the state's voter registration application, a voter who knowingly provides false information or knowingly makes a false declaration about their qualifications "will have committed a class C felony that is punishable by imprisonment for up to five years, a fine of up to ten thousand dollars, or both."

All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment. Eight states — Alabama, Arizona, Kansas, Louisiana, New Hampshire, South Dakota, Utah, and Wyoming — have laws requiring individuals provide proof of citizenship at the time of voter registration, whether in effect or not. Two states, Georgia and Mississippi, require a person provide proof of citizenship if their citizenship status cannot be verified by other means. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.

Verifying your registration

The site Vote WA, run by the Washington Secretary of State office, allows residents to check their voter registration status online.

Voter ID requirements

Washington is an all-mail voting state and does not require voters to present photo identification (ID). Voters may choose to vote in person at a local voting center. According to state law, “The county auditor shall require any person desiring to vote at a voting center to either sign a ballot declaration or provide identification.”

The following list of accepted ID was current as of March 2026. Click here for the Washington State Legislature's voter ID regulations to ensure you have the most current information.

“

The identification must be valid photo identification, such as a driver's license, state identification card, student identification card, tribal identification card, or employer identification card. A tribal identification card is not required to include a residential address or an expiration date to be considered valid under this section. Any individual who desires to vote in person but cannot provide identification shall be issued a provisional ballot, which shall be accepted if the signature on the declaration matches the signature on the voter's registration record.
