Choose the voting method that works for you. Deadlines depend on that method. Check the time and delivery requirements, not just the date. Military, overseas, and emergency voting may have separate rules.
01
Register
Submit a registration application to your county. After regular registration closes, register in person at a county-designated location and collect your ballot there. Current rules allow Election Day registration; confirm hours and the November 2 noon pause.
Regular mail registration postmark deadline
Postmark your registration form by October 5; it must arrive within three days, by October 8.
Visit a county-designated registration location and obtain your ballot in person. Confirm county hours; do not assume ordinary polling places register voters. Saturday registration is not available under the current court order.
Register or update your information at a county-designated location by 8 p.m. November 3 and obtain your ballot in person. This is separate from your ordinary polling place.
Any registered voter may vote absentee. Apply through your county election office or join the absentee list. Sign the return envelope and meet the receipt deadline. Late registrants must collect their ballot in person.
Absentee ballots mailed
Ballots are mailed to voters on the absentee list October 9.
Your county must receive the application by noon November 2. Applying this late requires collecting the ballot in person; allow more time if using mail.
Return your signed ballot envelope to the election office or an authorized polling place by 8 p.m. November 3. A postmark alone does not meet the deadline.
November 3, 2026. Poll hours: Generally 7:00 a.m.–8:00 p.m. Mountain time; some smaller precincts open later. Check your official ballot, voting location, and identification requirements before you go.
Date labels compare calendar dates in Mountain time; “Today” does not mean the cutoff time has not passed. Confirm local times with your election office.
