The Scoop on Colorado’s November 2026 Proposed Measures | Amendment 84 | Part 4 of 14

**Election Day is Tuesday, November 3, 2026.**

## Amendment 84: Mail Ballot Voter Identification

Amendment 84 would add an identification-number requirement to Colorado’s mail ballot verification process.

Voters would still sign their ballot envelope. They would also provide identifying information on the envelope’s self-affirmation—the statement voters sign when returning their ballot.

If required information were missing or could not be matched to the statewide voter registration database, election officials would have to notify the voter. **Election officials could not count the ballot until the discrepancy was corrected.**

Because the measure adds language to the Colorado Constitution, it requires **55 percent approval** to pass.

### An important detail about the wording

The ballot title describes the requirement as the last four digits of a Social Security number **or a Colorado driver’s license or identification card number**.

The measure’s actual text specifically refers to Colorado **REAL ID** credentials and also allows the last four digits of another qualifying Colorado identification number. It describes the elections covered as “federal or statewide,” while the ballot title says “federal or state.”

These distinctions are worth noticing. Some summaries describe every option as requiring only the last four digits, but the wording supplied in the measure does not express every identification option that way. Before assuming exactly what voters would write, read the full text—not just a campaign summary.

## What Your Vote Means

**A YES vote** would require identification information with a mail ballot, in addition to the voter’s signature. Missing or unmatched information would have to be corrected before the ballot could count.

**A NO vote** would leave the existing mail ballot verification requirements unchanged.

“Signature-only” is a useful shorthand for the current envelope-verification process, but it does not mean Colorado has no other voter identification requirements. Some first-time mail voters must also provide identification under existing rules.

## Official Ballot Language

Jefferson County’s ballot information page lists the question as follows:

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?

## Who Is Behind the Measure?

Amendment 84 was originally filed as **Initiative 362**. Its designated representatives are **Suzanne Taheri**, a former deputy secretary of state, and **Chuck Broerman**, a former El Paso County clerk and recorder.

The supporting campaign includes the **Colorado Voter Trust Initiative**. The supplied reporting also identifies **Advance Colorado** and the **Independence Institute** as supporters.

Opponents include **Defend Our Ballots**, **Vote Common Sense**, and the **League of Women Voters of Colorado**.

Campaign affiliations and funding are worth examining, but they do not settle whether a proposal is good policy. The important questions are what the amendment would do, what problem it addresses, and what consequences it could create.

## The Case for Voting YES—and the Counterarguments

### Additional verification could strengthen election security

Supporters say an identification number would provide a second check that a returned ballot belongs to the voter submitting it. Someone who obtains another person’s ballot would need more than a convincing signature.

Supporters describe this as an additional authentication step—not a replacement for signature verification.

#### The counterargument:

*Opponents say Colorado already verifies voter identity through registration procedures and checks signatures on returned ballots. They question whether another written identifier would prevent enough fraudulent ballots to justify the new burden.*

*An identification number is also not a secret password or proof of physical possession of an ID. Someone who knows or obtains that information could still misuse it.*

#### The question to weigh:

How much additional protection would this requirement provide, and would that improvement outweigh the mistakes and administrative work it could create?

### In-person voters already provide identification

Colorado requires identification for in-person voting. Supporters argue that asking mail voters for identification information is a reasonable way to make verification more consistent across voting methods.

Most voters already have a qualifying identification number or know their Social Security number.

#### The counterargument:

*Showing an identification document to an election worker is different from writing identifying information on a ballot envelope. The privacy implications and opportunities for clerical mistakes are different.*

*Opponents also point out that identification options for in-person voting are broader than the amendment’s ordinary mail-envelope options.*

#### The question to weigh:

Does consistency require identical procedures, or can different voting methods use different safeguards effectively?

### Numbers are less subjective than signatures

Signatures can change because of age, injury, illness, or ordinary variation. Comparing them involves judgment. Supporters say an identification number offers a more objective check: it matches the voter’s record, or it does not.

#### The counterargument:

*The amendment would retain the signature requirement, so it would not eliminate signature-related problems. It would add another possible mismatch.*

*Numbers can also be transposed, written illegibly, or absent from the relevant database record. A precise comparison is useful only when the underlying records are accurate and available.*

#### The question to weigh:

Would this improve verification in practice, or simply add another reason a legitimate ballot needs correction?

### The cure process protects voters who make mistakes

A missing or unmatched number would not automatically end a voter’s opportunity to have the ballot counted. Officials would have to notify the voter and explain how to correct the problem.

The measure allows voters to correct the issue using specified identification documents, including a U.S. passport, military identification, or tribal photo identification, submitted in person or digitally. It also provides broader correction options for certain voters covered by federal accessibility law.

#### The counterargument:

*A cure process works only if the voter receives the notice, understands it, and completes the correction in time. Travel, unreliable mail delivery, disability, or limited internet access can make that harder.*

*The amendment itself does not specify a correction deadline. The supplied sources describe the existing eight-day cure period as relevant, but that deadline should not be confused with language written into the amendment.*

#### The question to weigh:

Is an opportunity to correct a mistake enough protection when the new requirement itself creates the mistake?

### Additional verification could increase public confidence

Supporters say a visible second verification step could reassure voters who doubt election security. Public confidence matters, even when people disagree about the scale of the underlying risk.

#### The counterargument:

*Opponents argue that confidence should come from evidence, transparent procedures, and accurate explanations of existing safeguards.*

*A new requirement could undermine confidence if voters encounter unexpected mismatches or see eligible ballots go uncounted because corrections were not completed.*

#### The question to weigh:

Would this change build trust through demonstrably better security, or mainly offer reassurance without a clear improvement?

The supporting arguments are summarized in [The Denver Gazette’s voter guide](https://www.denvergazette.com/2026/10/02/identification-voting-ballot-colorado-amendment-84/?utm_source=https://whatsupamericans.com/blog/colorado-amendment-84-2026-election).

## The Case for Voting NO—and the Counterarguments

### Colorado’s existing system already provides meaningful safeguards

Opponents say signature verification, voter registration checks, and the existing cure process already provide effective safeguards. They argue that the case for adding a universal identification-number requirement has not demonstrated a widespread problem that warrants it.

#### The counterargument:

*Supporters respond that fraud does not have to be widespread before a preventive safeguard becomes worthwhile. A system can work well and still have vulnerabilities worth addressing.*

*They also argue that detecting fraud afterward is not the same as preventing an improper ballot from being counted.*

#### The question to weigh:

What evidence of vulnerability should justify changing the rules for every mail voter?

### Eligible voters could lose their votes over ordinary mistakes

A voter might leave the number blank, transpose digits, write unclearly, or provide information officials cannot match. Under the amendment, the ballot could not count unless the problem was corrected.

Opponents worry that some eligible voters would miss the notice or fail to complete the cure process.

#### The counterargument:

*Supporters say clear instructions, well-designed envelopes, voter education, and mandatory notification could reduce those problems. They argue that reasonable verification requirements need not exclude eligible voters when correction options are available*.

#### The question to weigh:

How many additional ballots would need correction, and how many voters would successfully complete it?

### Writing identifying information on an envelope raises privacy concerns

Opponents object to placing sensitive identifying information on a return envelope handled outside the voter’s control. Even partial identifiers can raise legitimate privacy concerns.

Kim Monson recommends voting NO on this basis despite supporting voter identification in principle.

#### The counterargument:

*Supporters say envelope design could shield the information. In the supplied account of the review hearing, a designated representative suggested a protective tab or similar feature.*

*However, a possible design safeguard is not the same as an explicit privacy requirement in the amendment’s text.*

#### The question to weigh:

Should voters approve the requirement before knowing what protections would prevent unnecessary exposure?

### Implementation would cost money and increase election workers’ workload

Counties would need to redesign envelopes, review additional information, notify more voters, and process corrections.

The supplied guide reports Blue Book estimates of **up to $2.7 million in combined state and local costs initially**, with **up to $1.2 million annually in future years**.

Additional work could complicate ballot processing, although these sources do not establish that results would necessarily be delayed by days or weeks.

#### The counterargument:

*Supporters argue that election security is a legitimate public expense. They say an additional verification step may be worth its cost if it prevents improper ballots and increases confidence.*

#### The question to weigh:

Would this be the best use of election funding compared with improving existing verification, registration accuracy, or voter outreach?

### Some voters could face greater difficulties than others

Opponents worry about voters with disabilities, older voters, people with unstable housing, and those who have difficulty receiving notices or obtaining documents.

The practical burden of correcting a mistake is not the same for everyone.

#### The counterargument:

*Supporters point to the Social Security-number option, digital correction, in-person voting alternatives, and the measure’s accessibility provision.*

*Opponents respond that those alternatives may help without removing every barrier.*

#### The question to weigh:

Are the available alternatives genuinely accessible to the voters most likely to need them?

**The proposal may impose more burden than its security benefit justifies**

Opponents call Amendment 84 a solution in search of a problem. Their concern is proportionality: every mail voter would face another requirement, while the demonstrated benefit remains disputed.

#### The counterargument:

Supporters say prevention should not wait for a major failure. Even isolated fraudulent ballots matter, particularly in close elections.

That does not settle whether this particular requirement would stop those ballots. Its effectiveness still needs to be evaluated rather than assumed.

#### The question to weigh:

Is this a targeted response to a demonstrated weakness, or a broad requirement with uncertain benefits?

**The Constitution is the wrong place for detailed election procedures**

Constitutional rules are harder to revise than ordinary statutes. If the identification requirement creates unexpected problems—or technology changes—fixing it could require another statewide vote.

Opponents say election administration needs room to adapt.

#### The counterargument:

Supporters may see that permanence as a benefit. A constitutional provision would prevent lawmakers from easily removing safeguards voters approved.

#### The question to weigh:

Does this policy need constitutional protection, or does its operational detail make flexibility more important?

Sources for these concerns and responses include [The Denver Gazette](https://www.denvergazette.com/2026/10/02/identification-voting-ballot-colorado-amendment-84/), [The Durango Herald](https://www.durangoherald.com/articles/news/amendment-84-increased-identification-on-mail-ballots/), [Kim Monson’s guide](https://kimmonson.com/colorado-voter-guide/2026/amendment-84/), and [Defend Our Ballots](https://defendourballots.com/).

**Conclusion**

The strongest case **for Amendment 84** is that requiring an identification number would add a second verification step to mail voting. Supporters argue this could make it harder for someone to submit another voter’s ballot, provide an objective check alongside signature verification, and increase public confidence in elections. The required notification and correction process would give voters an opportunity to resolve missing or mismatched information before their ballots are excluded.

The strongest case **against Amendment 84** is that an additional requirement could create new obstacles for eligible voters without a sufficiently demonstrated security benefit. Opponents argue that Colorado’s existing safeguards already provide meaningful protection, while missing numbers, clerical errors, and database mismatches could leave legitimate ballots uncounted if voters do not complete the correction process. They also raise concerns about privacy, implementation costs, and the difficulty of changing detailed election procedures in the Constitution.

**The central question is whether the additional verification would provide enough security to justify the added burden on voters and election officials.** Another question is whether the correction process and privacy protections would adequately address the risks the new requirement creates.

A **YES vote** favors adding identification-number verification to mail ballots. A **NO vote** favors retaining the existing verification requirements.
