Signatures submitted for Colorado initiative requiring mail-in ballots to contain a voter identification number

In Colorado, signatures were submitted to the secretary of state's office on July 16, 2026, for a ballot initiative related to voter identification requirements for mail-in voting.

The initiative — known as Initiative 362 — would add a new section to Article VII of the Colorado Constitution to require voters to provide both their signature and an identification number, such as:

• the last four digits of their Social Security number;
• a Colorado REAL ID number;
• a Colorado REAL ID driver's license number; or
• the last four digits of another Colorado identification number meeting federal REAL ID requirements.
