Eligibility Requirements
Overseas Voters
U.S. citizens living abroad have the right to vote as absentee voters, provided they are eligible to vote in their state. If you are living outside of the U.S. permanently, indefinitely, or temporarily, your voting rights stay with you, even if you never voted when you lived in the U.S. To vote from overseas:
- Complete and send an overseas voter registration/ballot request form to your election office in the U.S. This is one specific form that will register you as an overseas voter and request your absentee ballot – simultaneously.
U.S. citizens born overseas who have never resided in the US may register and vote in Colorado if their parent, legal guardian, spouse, or civil union partner is eligible to register and vote in Colorado. The voter should register using the same registration residence as their eligible parent, legal guardian, spouse, or civil union partner.
Military Voters
Service members and their eligible family members living outside their voting jurisdiction (within or outside the U.S.) are able to vote as absentee voters.
- If you are a service member, or an eligible family member, there is a single form to file for both voter registration and ballot request. It is often called the “Federal Post Card Application” or the FPCA form. This form must be re-filed with your election office each time you change location.
To vote as a service member or eligible family member:
- Complete and send a voter registration/ballot request form “FPCA” to your election office in the U.S. It is the same form in all states.
Identification Requirements

U.S. citizens living overseas may register and request a ballot using the overseas voter registration/ballot request form. You will have the following identification options when completing the form:
- Your Colorado Driver's License Number
- U.S. State or Territory or District Issued ID
- Last 4 Digits of your Social Security Number
- Or, state that you do not have the requested ID number/s
