Elections and Campaign Finance Washington 4 Minutes Read ยท published February 07, 2026 Flag of Washington

Seattle, Washington voters use ballot drop boxes administered by county election officials to return voted ballots securely and on time. This guide summarizes where drop boxes are placed, how and when to return a ballot, who enforces rules, common violations and practical steps for reporting problems or appealing determinations. Where the City of Seattle does not publish standalone ordinances on drop boxes, county and state election authorities set binding procedures for ballot returns and handling.[1]

How ballot drop boxes work in Seattle

Ballot drop boxes accept voted ballots 24/7 during the official ballot drop period established for each election. Boxes are secured, monitored, and emptied on an official schedule to preserve chain of custody; chain-of-custody and processing procedures are maintained by county election officials.[2]

  • Drop boxes open on the ballot mailing date and close at 8:00 p.m. on Election Day unless otherwise posted.
  • Ballots must be inside the official envelope and signed where required before deposit.
  • If a voter has a damaged or missing ballot, contact King County Elections for replacement options.
Always allow time for signature verification and delivery before the ballot deadline.

Accepted methods of return

Voters may return ballots by:

  • Depositing the completed ballot in an official drop box located in public, identified locations.
  • Mailing the ballot using the U.S. Postal Service; postage is typically prepaid for ballots mailed within the U.S.
  • Delivering to designated election office counters during business hours.

Ballot security and chain of custody

County election staff log box emptying times, transport ballots under secure procedures, and retain records to support audit trails and recounts. Video or tamper-evident seals may be used where provided.
