Amendment 84: Mail Ballot Voter Identification

What It Would Do

Amendment 84 would end Colorado's current signature-only verification for mail ballots. Voters would be required to write the last four digits of their Social Security number, or their Colorado driver's license or ID card number, on the outside of their return ballot envelope, in addition to signing it. Voters could still correct missing or incorrect information, including with alternative forms of ID, but a county clerk could not count the ballot until the problem is fixed. It requires 55% voter approval to pass, as a constitutional amendment.

Fiscal Impact

Estimates of the cost to implement this requirement statewide vary and were not consistently confirmed across sources as of this writing, so we aren't citing a specific dollar figure here.

Why We're Voting No

Boulder Progressives opposes Amendment 84 because it would pile a new identification requirement onto mail voting, Colorado's most popular and secure way to cast a ballot, creating fresh opportunities for eligible ballots to be flagged, delayed, or rejected over simple paperwork mismatches.
