How to Vote by Mail

In Colorado all registered voters will be sent a mail-in ballot they can choose to use or not. Your ballot must be received by 7pm on Tuesday, November 3!

Please note, your county clerk must receive your ballot no later than 7 p.m. on Election Day (November 3, 2020). The general recommendation is to mail your ballot at least one week before to allow enough time to meet that deadline.

If you are unsure whether your ballot will arrive on time through the mail drop it off in-person at either a drop-box or a drop-off location. Contact your county clerk and recorder for drop-off location information.
