Ballot drop boxes opened July 18 for the August primary election. Ballots must be postmarked by August 6 or returned to a ballot drop box by 8 p.m. on election day to be counted.

However, the Secretary of State's Office recommended voters who return their ballots on election day bring them to a ballot drop box instead of dropping them in the mail to ensure they are postmarked in time.

Washington voters will now receive prepaid postage on mail-in ballots thanks to a new law that went into effect in July and do not need to use a stamp.
