Update your voter info
Only you (or your county clerk) can change your voter registration. Here's how, in a few minutes.
Moved within Colorado
Update your address online with the Colorado Secretary of State. Have your Colorado driver's license or state ID number ready.
Moved out of Colorado
Cancel your Colorado registration, then register where you live now.
A family member passed away
We're sorry for your loss. Send a signed letter with their full name, date of birth and address to the county clerk in the county where they lived, or use the county's cancellation form for a deceased family member.

Got a ballot for someone who doesn't live here?
Don't put it in a drop box. Mark the envelope, write "Return to sender" on the front and put it back in the mail. That tells the county the address is out of date.
