Amendment 84 (Initiative 362): requiring a signature and an identification number on returned mail ballots

Amendment 84 would require a signature and a qualifying identification number on the self-affirmation of a returned mail ballot in federal or statewide elections. Election officials would notify voters of missing or unmatched information. The county clerk could not count the ballot until the discrepancy was corrected.

Kim's recommendation
NO
Vote No on Mail Ballot Voter Identification
Kim's Reasoning:

You must show ID to fly. You must show ID to ship a package via FedEx. You must show ID to purchase some cough syrups at Wal-Mart. You must show ID to purchase alcohol. You must show ID to purchase a lottery ticket. It only makes sense that you should provide ID to vote. However I am very concerned about providing the last four digits of the voter’s Social Security number, a Colorado REAL ID card or driver’s license number, or the last four digits of another Colorado identification number that meets federal REAL ID requirements on the outside of the envelope that we return our ballots in, therefore I recommend a NO vote on Amendment 84.

Certified ballot question
Certified ballot title

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

For federal and statewide elections, a returned mail ballot must include the voter’s signature and either the last four digits of the voter’s Social Security number, a Colorado REAL ID card or driver’s license number, or the last four digits of another Colorado identification number that meets federal REAL ID requirements. Officials must notify voters when required information is missing or cannot be matched, and cannot count the ballot until the discrepancy is corrected. Voters must correct the problem within eight days of Election Day under the existing cure process. Voters may submit a copy of a qualifying ID, U.S. passport, U.S. military ID or tribal photo ID in person or digitally to correct it. Voters entitled to vote otherwise than in person under the federal Voting Accessibility for the Elderly and Handicapped Act may use the broader identification options allowed by Colorado law.

A no vote means

Mail ballots continue to use the existing signature and self-affirmation requirements.

The amendment has no expiration date. It would take effect on the governor’s proclamation after voter approval, within 30 days after the official canvass.

TABOR treatment

The measure sets no tax and no rate. Colorado issues TABOR refunds when state revenue exceeds the constitutional limit. Table 1 of the fiscal impact statement shows no change in those refunds and no change in state revenue in FY 2026-27, FY 2027-28 or FY 2028-29. The note's State Revenue section says that the Department of State is funded mainly by business filing fees and that "fees may need to be raised to cover all or some of the costs of this bill", set administratively by the department.

Cost signal

The fiscal note estimates additional state spending of $100,000 in FY 2026–27, $260,000 in FY 2027–28 and $20,000 in FY 2028–29, all from cash funds. Its table shows no change in state revenue, transferred funds, TABOR refunds or staffing in those years. County costs are not quantified; the note says the state reimburses a portion.

The measure01

Amendment 84 would require a signature and an identification number on a returned mail ballot

Amendment 84 would add section 13 to article VII of the Colorado Constitution under the heading "Voter Authentication". Its first sentence says that "FOR ANY FEDERAL OR STATEWIDE ELECTION, A VOTER IS REQUIRED TO AFFIX THEIR SIGNATURE AND INCLUDE EITHER THE LAST FOUR DIGITS OF THEIR SOCIAL SECURITY NUMBER OR COLORADO REAL IDENTIFICATION NUMBER OR COLORADO REAL IDENTIFICATION DRIVER’S LICENSE NUMBER", citing the federal REAL ID Act and sections 42-2-101, 42-2-301 and 42-2-402 of the Colorado Revised Statutes, "ON THE SELF-AFFIRMATION OF A RETURNED MAIL BALLOT". The self-affirmation is the statement a voter signs on the return envelope. A voter may instead write "THE LAST FOUR DIGITS OF ANOTHER FORM OF COLORADO IDENTIFICATION THAT MEETS THE REQUIREMENTS OF THE FEDERAL REAL ID ACT OF 2005 OR SUCCESSOR LEGISLATION." Colorado's current signature and self-affirmation rules for mail ballots are in the election code, and section 13 would place this requirement in the constitution. A no vote leaves current law unchanged.

Subsection (1) requires voters to write identifying information on the self-affirmation. It does not require them to send or show an identification document with the returned ballot. Subsections (2) and (3) specify documents voters may provide to correct a discrepancy. The April 13, 2026 fiscal summary says ballots must be redesigned to accommodate the changes.

The ballot title and the text describe the identification differently. The title voters will read says "their Colorado driver’s license or identification card number". The section names the Colorado REAL identification number and the Colorado REAL identification driver's license number, which are the credentials issued under the federal REAL ID Act, and the alternative it allows is another Colorado identification meeting that act's requirements. The title says "for any federal or state election"; the section says "ANY FEDERAL OR STATEWIDE ELECTION".

Who placed it on the ballot

Amendment 84 qualified for the ballot through the petition process. The review and comment memorandum of April 1, 2026, from Legislative Council Staff and the Office of Legislative Legal Services, is addressed to Suzanne Taheri and Chuck Broerman as the measure's designated representatives. The memorandum covers Initiatives 362, 363 and 364 together and says they were submitted by the same designated representatives.

The title and the text describe the identification differently

The ballot title says "their Colorado driver’s license or identification card number". The text of the measure names the Colorado REAL identification number and the Colorado REAL identification driver's license number, the credentials issued under the federal REAL ID Act.

The ballot question and the text of the measure describe the requirement differently
Elections covered
The question says "for any federal or state election".
The section says "FOR ANY FEDERAL OR STATEWIDE ELECTION".
Identification numbers accepted
The question says "their Colorado driver’s license or identification card number".
The section names the "COLORADO REAL IDENTIFICATION NUMBER OR COLORADO REAL IDENTIFICATION DRIVER’S LICENSE NUMBER", the credentials issued under the federal REAL ID Act of 2005, and allows the last four digits of another Colorado identification meeting that act's requirements.
Placement of the information
The question says the information goes "on the outside of their mail ballot".
The section says it goes "ON THE SELF-AFFIRMATION OF A RETURNED MAIL BALLOT", the statement a voter signs on the return envelope.
Certified ballot title; text of Initiative 362, article VII section 13 (1)
The terms the measure uses
Self-affirmationThe statement a voter signs on the return envelope of a mail ballot. The measure requires the identification number to be written "ON THE SELF-AFFIRMATION OF A RETURNED MAIL BALLOT", alongside the signature.
REAL IDA federal standard for state-issued identification, set by the REAL ID Act of 2005. The measure names the Colorado REAL identification number and the Colorado REAL identification driver's license number, and allows the last four digits of another Colorado identification "THAT MEETS THE REQUIREMENTS OF THE FEDERAL REAL ID ACT OF 2005 OR SUCCESSOR LEGISLATION".
Statewide voter registration databaseThe state's central record of registered voters. Under the measure an election judge must confirm that the information on the self-affirmation "MATCHES THE VOTER’S INFORMATION CONTAINED IN THE STATEWIDE VOTER REGISTRATION DATABASE".
Election judgeThe election worker who reviews returned mail ballots for the county. The fiscal note says the measure would increase the information election judges review and the staffing hours counties need.
County clerk and recorderThe county official who runs elections. Under the measure the clerk or other designated election official sends the voter notice of the process to correct a discrepancy and does not count the ballot until it is corrected.
Curing a discrepancyCorrecting a missing or unmatched entry on the self-affirmation so that the ballot can be counted. The fiscal note calls this curing; the measure says the clerk "SHALL NOT COUNT THE BALLOT UNTIL THE DISCREPANCY IS CORRECTED" and sets no deadline for the correction.
The Voting Accessibility for the Elderly and Handicapped ActA federal law under which certain voters have the right to vote other than in person. A voter covered by it may correct a discrepancy with "ANY FORM OF IDENTIFICATION DEEMED ACCEPTABLE UNDER SECTION 1-1-104 (19.5)" of the Colorado Revised Statutes.

The money02

State and county costs, and possible business filing fee increases

The May 14, 2026 fiscal note estimates additional state spending of $100,000 in FY 2026–27, $260,000 in FY 2027–28 and $20,000 in FY 2028–29, paid from cash funds. Its table shows no change in state revenue, transferred funds, TABOR refunds or staffing in those years.

The Department of State would spend an estimated $100,000 in FY 2026–27 and $200,000 in FY 2027–28 on a voter education campaign. The note also estimates $20,000 in outreach and printed materials for each presidential primary, statewide primary and general election. Its FY 2027–28 total is $260,000, but it does not provide a line-by-line reconciliation of that total.

The Department of State relies mainly on business filing fees and may adjust them to cover its direct and indirect costs. The fiscal note says fees may need to rise to pay some or all of the measure’s costs. The department would decide which fees change, when they change and the amounts, based on its cash fund balance and program costs.

County clerks would face higher costs for election-worker hours and overtime, voter outreach, printing and postage, digital security, and redesigned ballots and envelopes. Election judges would review more information, and more ballots would need correction. The fiscal note does not quantify these costs; it says the state reimburses a portion.

Because Vote Common Sense’s registration opposes nine measures, its totals cannot be attributed to Amendment 84 alone.

Business filing fees may rise

The Department of State relies mainly on business filing fees and may adjust them to cover its direct and indirect costs. The fiscal note says fees may need to rise to pay some or all of the measure’s costs. The department would decide which fees change, when they change and the amounts, based on its cash fund balance and program costs. The fiscal table nevertheless estimates no revenue change in FY 2026–27, FY 2027–28 or FY 2028–29.

Fiscal impact statement, May 14, 2026
Measure provisions03

Missing or unmatched information must be corrected before counting

The section states one consequence and one cure. If the voter "FAILS TO FILL OUT ALL OR PART OF THE REQUIRED AFFIRMATION", or if an election judge cannot confirm that the information "MATCHES THE VOTER’S INFORMATION CONTAINED IN THE STATEWIDE VOTER REGISTRATION DATABASE", the clerk or other designated election official "MUST SEND NOTICE TO THE VOTER INFORMING THEM OF THE PROCESS TO CORRECT THE DISCREPANCY", and "THE COUNTY CLERK AND RECORDER SHALL NOT COUNT THE BALLOT UNTIL THE DISCREPANCY IS CORRECTED." The fiscal note describes that step differently. It says "the ballot is sent back to the voter to cure any discrepancy". The section requires notice of the process to correct it, not return of the ballot.

Subsection (2) lists what corrects a discrepancy: a copy of the identification named in subsection (1), a United States passport, a United States military identification card or tribal photo identification, delivered "IN PERSON OR DIGITALLY" to the clerk or other designated election official. Subsection (3) covers voters who vote other than in person under the federal Voting Accessibility for the Elderly and Handicapped Act; they may use any identification acceptable under section 1-1-104 (19.5) of the Colorado Revised Statutes. The memorandum cites that same section as where current law allows many forms of identification in connection with voting. The section sets no deadline for making the correction.

A returned mail ballot's path under section 13
The voter signs the self-affirmation on the return envelope and writes the identification number on it.
An election judge checks that information against the statewide voter registration database.
If part or all of the affirmation is not filled out, or the election judge cannot confirm a match, the county clerk and recorder or other designated election official must send the voter notice of the process to correct the discrepancy.
The clerk does not count the ballot until the discrepancy is corrected.
The voter may correct the discrepancy by providing a copy of the identification named in subsection (1), a U.S. passport, a U.S. military identification card or tribal photo identification, in person or digitally. Voters covered by the federal Voting Accessibility for the Elderly and Handicapped Act may instead provide identification accepted under section 1-1-104(19.5), C.R.S., or its successor.
The fiscal note's Summary of Measure says "the ballot is sent back to the voter to cure any discrepancy". The section requires notice of the process to correct it.
The section sets no deadline for correcting a discrepancy. The reviewers asked whether a ballot that is not counted is rejected and set aside under section 1-7.5-204 (2) of the Colorado Revised Statutes.

Text of Initiative 362

The measure's path to the ballot

Suzanne Taheri and Chuck Broerman are the designated representatives for Amendment 84 (Initiative 362). They submitted Initiatives 362, 363 and 364 as a series. Amendment 84 qualified through the petition process.

The reviewers also asked whether the measure's correction process replaces the cure processes already in sections 1-7.5-107.3 and 31-10-910.3 of the Colorado Revised Statutes. A designated representative answered at the April 3 hearing: "No, we think it tracks with the current process, but we don't think it has to be replaced."

The Title Board voted 3–0 on April 15, 2026 to approve the single subject, change the draft title and set the title. The amendment requires 55% of the votes cast because it adds constitutional language. Proponents submitted signatures on July 16, and the Secretary of State found them sufficient on August 26, qualifying the measure for the November ballot.

Suzanne Taheri and Chuck Broerman submitted Initiative 362 with two other drafts

Suzanne Taheri and Chuck Broerman are the designated representatives for Amendment 84 (Initiative 362). They submitted Initiatives 362, 363 and 364 as a series. Amendment 84 qualified through the petition process.

Initiatives 363 and 364 would also have allowed a full date of birth on the self-affirmation. Initiative 364 would have required reimbursement of county clerks’ reasonable implementation costs. Amendment 84 contains neither provision.

Review and comment memorandum, April 1, 2026
Five questions the legislative reviewers put to the proponents
A mark instead of a signatureCurrent law lets a voter who cannot sign complete the self-affirmation by "making a mark on the self-affirmation, with or without assistance, witnessed by another person". The reviewers asked: "Is it the proponents’ intent to require a signature on the self-affirmation and to disallow making such a mark for voters who are unable to sign their name?" Section 13 requires a signature and provides no exception for a mark. At the April 3, 2026 review and comment hearing, a designated representative answered that this "is not our intent": in the proponents' view, current law already treats a witnessed mark as a signature, so "we don't feel like we need to clarify that in a constitutional measure."
The election judge's check of the number"How will an election judge verify that the identification number information required by the initiatives to be included on the self-affirmation matches the voter’s information contained in the statewide voter registration database?" The reviewers noted that county clerks have access to digitized signatures for comparing a signature on a return envelope, and that the identification a voter used to register may not match what the measure requires, so "will election officials be able to use the information on the self-affirmation to actually verify or match the voter with the statewide voter registration database?" At the hearing, a designated representative said the information "is already captured at DMV and can just be uploaded into the voter registry," then added, "we think if it doesn't match, there's a cure process."
Automated signature verification"Current law allows the use of automated signature verification methods for mail ballots. Would those methods still be available under the proposed initiatives?" At the hearing, a designated representative answered yes: "we believe they can just program those machines" to read the four digits.
Safeguards for the information on the envelope"Are there specific safeguards to protect against public access to, or disclosure of, the personal identifying information required on the self-affirmation?" At the hearing, a designated representative said they believed that "in the design of the envelope there can be a tab or a way to secure that away from the general public."
Three forms of identification, or fourThe reviewers wrote that "Current law allows for many forms of identification in connection with voting", citing section 1-1-104 (19.5) of the Colorado Revised Statutes, and asked the proponents about the filing submitted for review: "is it the proponents’ intent, except for voters covered by the federal Voting Accessibility for the Elderly and Handicapped Act, that voters may only provide the numbers associated with one of the three listed forms of identification"? The certified text's section 13 (1) names three forms and also allows the last four digits of another Colorado identification that meets the federal REAL ID Act, and section 13 (3) reaches the broader statutory list only for voters covered by that federal act. At the hearing, a designated representative answered "yes, that is our intent."

Text of the measure

Be it enacted by the People of the State of Colorado: SECTION 1. In the constitution of the state of Colorado, add Section 13 to article VII as follows: Section 13. Voter Authentication (1) FOR ANY FEDERAL OR STATEWIDE ELECTION, A VOTER IS REQUIRED TO AFFIX THEIR SIGNATURE AND INCLUDE EITHER THE LAST FOUR DIGITS OF THEIR SOCIAL SECURITY NUMBER OR COLORADO REAL IDENTIFICATION NUMBER OR COLORADO REAL IDENTIFICATION DRIVER’S LICENSE NUMBER, AS CODIFIED IN 49 U.S.C.

A VOTER MAY ALTERNATIVELY INCLUDE THE LAST FOUR DIGITS OF ANOTHER FORM OF COLORADO IDENTIFICATION THAT MEETS THE REQUIREMENTS OF THE FEDERAL REAL ID ACT OF 2005 OR SUCCESSOR LEGISLATION. IF THE VOTER FAILS TO FILL OUT ALL OR PART OF THE REQUIRED AFFIRMATION, OR IF AN ELECTION JUDGE IS UNABLE TO CONFIRM THAT THE INFORMATION PROVIDED MATCHES THE VOTER’S INFORMATION CONTAINED IN THE STATEWIDE VOTER REGISTRATION DATABASE, THE COUNTY CLERK AND RECORDER OR OTHER DESIGNATED ELECTION OFFICIAL MUST SEND NOTICE TO THE VOTER INFORMING THEM OF THE PROCESS TO CORRECT THE DISCREPANCY. THE COUNTY CLERK AND RECORDER SHALL NOT COUNT THE BALLOT UNTIL THE DISCREPANCY IS CORRECTED. (2) A DISCREPANCY MAY BE CORRECTED BY PROVIDING A COPY OF THE VOTER’S IDENTIFICATION IN SUBSECTION (1) OF THIS SECTION, US PASSPORT, US MILITARY IDENTIFICATION CARD, OR TRIBAL PHOTO IDENTIFICATION, IN PERSON OR DIGITALLY, TO THE COUNTY CLERK AND RECORDER OR OTHER DESIGNATED ELECTION OFFICIAL.
