Voter Registration: Idaho

General Date: Nov. 7, 2023


Registration Deadline: A citizen may register with their County Clerk up until 24 days prior to any election. You must provide an Idaho Driver’s License number, Idaho Identification Card number, or the last four digits of your Social Security number. You may register in person with your County Clerk or by mail if your registration form is postmarked 25 days before any election.


Idaho also provides for Election Day registration. To register on Election Day, bring a document with a valid address in your precinct and photo identification when you go to your polling place. Students of a post-secondary education institution may use student photo identification and a fee statement with an address in the precinct from their school to register on Election Day.


Re-registration with their County Clerk is required if an elector changes their address. Re-registration is required if an elector changes their name by marriage or for another reason. If an elector has not voted in a Primary or General Election in the last four years re-registration is also required to be listed as a qualified elector in Idaho.


Beginning July 1, 2023 all new voter registrations will need to provide one of the approved proof of residence documents in order to complete the registration process.


You can register to vote online here.


Party Affiliation: In primary elections, unless the party chooses to allow others outside the party to participate in its primary election, only registered voters of a political party may vote to select their party’s nominees. In other words, at primary elections, registered Republicans may vote only for Republican candidates, and registered Democrats may vote only for Democratic candidates. Persons who are registered as “unaffiliated” (meaning not affiliated with any political party) may not vote for partisan candidates in primary elections unless the party decides to allow them. However, an unaffiliated voter may affiliate with a party up to or on Election Day and vote in that party’s election. Independent candidates appear on the ballot only at the general election. You can declare your party affiliation by filling out this form.


Changing Party Affiliation: For a primary election, an elector may change their political party affiliation or become “unaffiliated” by filing a signed form with the county clerk no later than the 10th Friday prior to such primary election, as provided for in Idaho Code § 34-704.

An “unaffiliated” elector may affiliate with the party of the elector’s choice by filing a signed form up to and including election day. The application form for an absentee ballot described in Idaho Code § 34-1002, may also be used for this purpose.

An “unaffiliated” elector may affiliate with the party of the elector’s choice on or before election day, by declaring such political party affiliation to the poll worker. The poll worker shall then record in the poll book the elector’s choice. After the primary election, the county clerk shall record the party affiliation so recorded in the poll book as part of such elector’s record within the voter registration system as provided for in Idaho Code § 34-437A.
