You can register to vote in Colorado (or update your address) at any time up to & including Election Day at any Voter Service Center in your county. 

Drop it off:

You may need to include a photocopy (or printed photo) of an acceptable form of ID with your mail ballot­­—please refer to your mail ballot to see if this is required of you.
