A yes vote would require voters in federal and state elections to add the last four digits of their Social Security number, Colorado driver's license or Colorado ID card to the outside of their signed mail ballot, and a ballot with a missing or unmatched number would not count unless the voter fixes it within eight days after the election.² Where in the source: pp. 24-25
