Register online no later than 11:59 p.m. Tuesday, October 13, 2026. Mailed registration cards must be postmarked by Tuesday, October 13, 2026. Register in person at your county elections office (or certain state agencies like the DMV) by Tuesday, October 13, 2026 (21 days before Election Day).
Mailed ballots must be postmarked by Election Day (Tuesday, Nov 3) AND arrive by Tuesday, November 10, 2026. Ballots left in an official drop box or at the county elections office must be in by 8 p.m. Nov 3 (the 8 p.m. time applies to drop boxes, not to postmarks). If mailing on Election Day, check the last pickup time so your envelope gets a Nov 3 postmark.
