Make Your Plan To Vote
1. Confirm your registration
Register or check your voter record at GoVoteColorado.gov where you can also update your information or print a paper registration form. Colorado lets you register up to and including Election Day. On Election Day, register in person at a polling center and bring an accepted ID.
2. Choose how you'll vote
Vote by mail, return your ballot at a drop box, or vote in person. Mail delivery times vary, so send your ballot early. Voting in person? Plan your ride and get in line before 7 p.m. on Election Day. Find your voting location or drop box location at GoVoteColorado.gov. Keep a backup plan—a drop box or polling center works if your mailed ballot might run late.
3. Learn what's on your ballot
The measures on your ballot shape daily life in our communities. Look up your sample ballot, and read the nonpartisan Blue Book, mailed to every household and available online in English and Spanish (Libro Azul).
