How to vote in CT, what to bring

Returning voters 

Most voters will need either:

  • (a) A Social Security Card or
  • (b) Any pre-printed form of ID showing the voter’s name together with his or her (1) address, (2) signature, or (3) photograph

A voter without ID will be required to sign Form ED-681, which attests his or her identity under penalty of false statement.

First-time voters

Most first-time voters will need either:

  • (a) A copy of a current and valid photo identification that shows name and address or
  • (b) A copy of a current utility bill, bank statement, government check, paycheck or government document that shows your name and address

Without either of these, voters would need to cast a provisional ballot. 

  • Details on provisional ballots, according to the Connecticut Secretary of State: Election officials issue provisional ballots under certain circumstances and only when a candidate for federal office is on the ballot. Provisional ballots do not include candidates for state or local elections. To vote by provisional ballot, people must fill out an application under penalty of false statement attesting to their eligibility and current standing as an elector in the town where the polling place is located. Registrars have six days after a primary or general election to authenticate the information on each provisional ballot. The ballots are kept separate and counted only after the registrars verify their eligibility.
