Colorado has multiple options to help residents register to vote in the November election. Colorado is one of 32 states that lets voters fill out their registration online. To vote online, Coloradans need to provide a form of state-recognized identification. If residents do not have an ID, they can complete a paper form and mail it to the state elections office. 

Colorado also offers voter registration in-person on Election Day
