You can register online or download a form from our website and return it to the Elections office. You can also register in person during office hours at the Elections office. More information is available on our Registration page.

To register to vote in King County, you must be:

• A citizen of the U.S.
• A legal resident of Washington
• At least 18 years old by Election Day

You must register to vote at least 29 days before an election in order to be eligible to vote in that election. If you are not registered in Washington, you can register in person at the King County Elections Office up to eight days before the election. To see the deadlines for the next Election, visit the Registration page.

King County conducts all elections by mail, which means that all registered voters receive their ballots in the mail rather than going to a polling place. To vote, register with King County and make sure your information is up to date using the personalized Voter Guide.

If you do not receive a ballot in the mail, contact the elections office at 206-296-VOTE or elections@kingcounty.gov or visit the Elections office.

A few things to remember:

• Use a black ink pen
• Follow directions carefully
• Remove the stub on the top of the ballot
• Sign the voter’s oath on the back of the return envelope
• Read the entire ballot before filling it out
• Lost or damaged ballots can be replaced by the Elections office

King County Elections compares the signatures of returned ballot envelopes against the signature on file with your voter registration. If you forget to sign the envelope or the signatures don’t match, Election officials will attempt to contact by phone and mail to take care of the problem. Voters can update their signature for future elections by completing a new registration form.

Do not vote using that ballot. Call 206-296-VOTE or visit the Elections office for a replacement ballot. The name and signature on your return envelope must match the name and signature in the official voter registration file.

You may receive a call or mail from King County Elections regarding the signature on your ballot. Respond promptly in order to make sure your ballot can be counted. Even if Election Day is passed you may still have time to fix any issues or problems.

No, we will count only those races for which you voted and your ballot will still be processed even if you don’t vote for every race.

Don’t worry, your ballot is correct. The measures and races on your ballot are those that you are eligible to vote and reflect the districts in which you are registered to vote. The voters’ pamphlet may cover several different districts and as a result, some items may appear in the pamphlet that are not on your ballot.

These are printed as submitted to our office by candidates. King County Elections does not correct punctuation, grammar, syntax errors or inaccurate information.

The explanatory statements are prepared by each district’s attorney, stating the effect of the ballot measure if passed into law. In addition, districts can choose to appoint committee members to write statements in favor or opposition to the measure. King County Elections is not responsible for the content of statements.

King County Elections is located at 919 Southwest Grady Way, Renton, WA 98057-2906. Map and directions. 

You can return your ballot by mail - requires first class postage and must be postmarked by Election Day. You can also return your ballot at a ballot drop box or an accessible voting center by Election Day.

Visit the ballot drop box page for information on locations and when they are open.

You can use the Ballot Tracker to see the progress of your ballot at three points:

• Track point #1: Your ballot packet was assembled and mailed to you.
• Track point #2: King County received your completed ballot.
• Track point #3: Your signature was verified and your ballot proceeded through the counting process.

Voters can return their completed ballots as soon as they receive them in the mail. The deadline to postmark or drop off your ballot is Election Day. Return your ballot as early as possible for it to be included in results reported on Election Night, and to allow more time for Elections to connect with you if there are any issues verifying your signature.

As an alternative, you may use a regular mailing envelope instead of the security envelope to ensure the secrecy of your ballot. However, that is not required. Regardless, return your ballot, it will still be processed and counted with other mail ballots.
