FAQs

What is the voter registration deadline in Colorado?

Colorado law allows you to register to vote through Election Day. But please note that how you register to vote impacts how you receive your ballot. In order to receive your ballot by mail:

  • Submit an application through a voter registration drive no later than 22 days before Election Day.
