All Colorado elections are conducted by mail, with every registered voter receiving a ballot. Photo ID is required the first time you vote if not provided during registration.

Birth Certificates

A birth certificate may be needed to prove citizenship or obtain other identity documents.

Issuing Agency: Colorado Department of Public Health and Environment (CDPHE) and county vital records offices Fee: $25 for first copy, $20 for additional copies Standard Processing Time: 30 business days for online orders Expedited Option: FedEx expedited shipping available for $25

How to Request

Notes: Birth certificates can be obtained from any Colorado county vital records office regardless of where in Colorado you were born. Starting May 1, 2025, Denver will charge a 2.5% service fee for credit/debit card transactions. Surcharge applies for credit/debit card payments through the state system.

Proof of Citizenship Documents

You may need proof of citizenship to register to vote or to obtain a REAL ID.

Accepted Documents

  • US Passport
  • US Birth Certificate (certified copy)
  • Naturalization Certificate (certified copy)
  • Colorado Driver’s License (for US citizens only)
  • Colorado ID card issued by Department of Revenue
  • US Military ID with photograph
  • Federal or State government employee ID with photograph
  • Valid pilot’s license issued by Federal Aviation Administration

How to Obtain Citizenship Proof

For US-born citizens: Obtain a certified copy of your birth certificate from the vital records office in your birth state. For naturalized citizens: Apply for a replacement Certificate of Naturalization through USCIS using Form N-565 if original is lost. For passport: Apply through US State Department at passport acceptance facilities, including Colorado State University, with required documentation and fees.

For US Citizens Abroad

US citizens abroad can apply for passports through US embassies and consulates worldwide. Birth certificates can be obtained by mail from US vital records offices. Naturalization certificates can be replaced by filing Form N-565 with USCIS, which can be done from overseas.

Notes: Colorado currently verifies citizenship primarily through DMV registration and online systems using government databases. Recent legislative attempts (HB21-1086, HB19-1156) to require proof of citizenship documents for voting have been proposed but their current status should be verified. Documents issued to non-lawfully present individuals are not acceptable. Voters must attest under penalty of perjury that they are US citizens.

Voting Laws & Legal Resources

Colorado operates as an all-mail voting state, meaning every registered voter automatically receives a mail ballot 22 days before Election Day. Voters can also vote in person at Voter Service and Polling Centers (VSPCs) during early voting periods or on Election Day. All voters must provide valid ID when voting in person, which must show a Colorado address if the ID includes an address. Utility bills must be current within 60 days. Colorado allows voter registration through Election Day, though to automatically receive a mail ballot, voters must register at least 8 days before the election (22 days if registering through a voter registration drive). First-time mail voters who registered by mail without providing ID must include a photocopy of acceptable identification with their ballot. People serving a sentence of confinement for a felony conviction cannot vote, but voting rights are restored upon completion of the sentence.

Recent Law Changes

  • 2025: Colorado Voting Rights Act (SB25-001) was enacted
  • Impact: Creates new voting rights protections and administrative requirements for elections, with appropriation of $75,432 for implementation
