For all primaries and caucuses there are deadlines for registration just as there are for the General Election. You will need to check your state's deadlines. In many states, you must indicate a party affiliation when you register to vote in order to vote in that party's primary election. The ballots are different, depending on your party, and this is how they know which ballot to provide to you.

For more information on your state's voting system and registration deadlines, go to the State Voting Requirements page and select your state. Click on the “Upcoming Election Dates & Deadlines” tab, for a drop-down menu of important local election dates and deadlines.

To register to vote, go here. For more information about registration, visit the Registration section of this FAQ. For a step by step guide on how to register, please see the question “What do I need to do if I’ve never registered before?” in the First Time Voters section, also in this FAQ.

Note: you only need to register to vote once for any residence at which you live, that is, you only need to register once for both your state’s primary and General Election. You will only need to re-register if your voting residence address changes or if you become an inactive voter.

To check your registration status, go to our State Voting Requirements page, input your state, and click on the last tab labeled “State Lookup Tools – Am I Registered? Where’s my Ballot?”. Once this tab is opened, there should be many links – click on the link labeled “Am I Registered?”. This link will take you to your state’s website where you can input your information and confirm that you are registered.
