Colorado Amendment 84 — Mail Ballot Voter Identification

Ballot measure · November 3, 2026

What it does
Shall there be an amendment to the Colorado Constitution requiring a voter to sign and include the last four digits of their social security number or their Colorado driver’s license or identification card number on the outside of their mail ballot for any federal or state election, and, in connection therewith, allowing the voter to correct missing or incorrect information, including with alternative forms of identification; and prohibiting a county clerk and recorder from counting the mail ballot unless the problem is fixed?
A YES vote means
A yes vote requires voters to sign and write the last four digits of their Social Security number or Colorado ID number on the outside of mail ballots in federal and state elections, with a process to fix missing information.
A NO vote means
A no vote keeps current mail ballot verification, which relies on signature verification without the ID-number requirement.
