Voter Registration Information

Voters in City elections are registered electors who live within the Thornton City limits. For those who are not already registered to vote, they may register for the November 2023 Regular Municipal Election, in one of the following ways:

• If an individual registers to vote by mail, a voter registration agency (including the Thornton City Clerk's Office), a local driver's license facility, or online through www.govotecolorado.gov by October 30 and the Adams County Clerk and Recorder will automatically mail a ballot. 
• Voter registration forms are available at several locations including the Adams County Election Office, any City Clerk's Office, Motor Vehicle offices, or www.govotecolorado.gov.
• If an individual registers to vote through a voter registration drive, their application must be submitted no later than October 16.
• Individuals may also register to vote by appearing in-person at a Voter Service and Polling Center through and including Election Day. After October 30, individuals must visit one of the Voter Service and Polling Centers in Adams County to register and receive a ballot. Go to www.adamsvotes.com for locations.
