Frequently asked questions

What is a ballot drop box?

A ballot drop box is a way for voters to securely return their mail ballot, without the cost of postage.

When are drop boxes open?

Drop boxes will be open to accept ballots 19 days prior to and including Election Day. They will be open 24 hours each day and will close at 8 p.m. on Election Day.

How do I use a ballot drop box?

Carefully follow the instructions on the ballot envelope. Place the ballot in the security envelope, seal all envelopes, sign the outer envelope, and deposit your ballot packet into the box.

How do I know my ballot is secure?

Ballots are collected regularly from each drop box by King County Elections. Two official elections workers will use a chain of custody process to transport all ballots.

Ballot packets are delivered to the Elections facility where they are processed with other returned mail ballots. The signature on every ballot is checked against the voter’s registration file and if it matches, the ballot moves forward.
