If you don’t have one of these numbers, you must provide the last four digits of your Social Security Number. If you don’t have any of these numbers, you must indicate this on your voter registration form. If you don’t follow these guidelines, you’re voter registration form will not be processed.

Colorado has been an all vote-by-mail state since 2013.  You do not need to provide ID if you vote-by-mail. Oddly, you will need to provide ID if you vote in person.
YES! If you lose your Absentee Ballot or otherwise destroy it, you may vote during the Early Voting period or on election day. When you vote, you will be provided a provisional ballot, and you must affirm that you requested an Absentee Ballot and will not vote on it.
