Colorado Weighs Amendment 84 on Ballot Verification

Live Poll

Should voters have to write part of their social security or license number on ballots?

Colorado voters will decide Amendment 84 on November 3, 2026, a measure requiring the last four digits of a social security number or driver's license number on the outside of each ballot, in addition to the voter's signature.

Why it matters

Supporters argue matching four digits is simpler and faster than analyzing signatures, which they say are more inconsistent among younger and older voters who rarely provide physical signatures. The change would modernize how ballots are verified for Colorado elections.

Amendment 84 would add a four-digit identifier requirement to ballot envelopes, alongside the existing signature requirement. The stub provides no vote projections or measured verification rates, and how the measure would perform in practice remains unaddressed.

The details

Voters would write the last four digits of their social security number or driver's license number on the outside of their ballot, and election officials would match those digits to verify it. Proponents say the change would make elections more secure while speeding up verification.

Political Context

Amendment 84 layers a four-digit identifier requirement onto Colorado's existing signature-based ballot verification. Opponents' specific counter-arguments are not included in the extraction, so the measure's pushback cannot be detailed here.

If approved, Colorado voters would need to write the last four digits of a social security or driver's license number on their ballot in addition to signing it. Voters should confirm the requirement before returning their ballot for the November 3, 2026 election.

The takeaway

Voters casting ballots in Colorado's November 3, 2026 election should be ready to include the last four digits of an identification number alongside their signature if Amendment 84 passes.
