Where and how to change your party registration

You change your political party registration through your state or county election office, not through the national parties themselves. The process is usually free and takes 10 to 15 minutes. Most states let you change your registration online, by mail, or in person at your local election office or DMV.

Start by finding your election office's website — search "[your state] secretary of state election office" or "[your county] voter registration." The site will have a form or online portal labeled "change party affiliation," "change party registration," or "update voter registration." Some states call this "party preference" instead of party registration.

If your state does not offer online registration changes, you can request a form by mail or phone, fill it out, and return it. A few states still require you to change your registration in person at the election office or DMV, though this is becoming less common. The election office will send you confirmation once the change is processed, usually within one to four weeks.

Key Takeaways

  • You register with a political party through your state or county election office, and the process is free and takes about 15 minutes.
  • Most states offer online registration changes on their election office website; some require mail or in-person registration at the DMV or election office.
  • Your new party registration takes effect immediately for online changes or within one to four weeks for mail submissions.
  • Changing your party registration does not affect your voter registration status or your right to vote in general elections.
  • Some states have closed primaries, meaning you can only vote in your registered party's primary; others allow anyone to vote in any primary regardless of registration.

What documents you need

You need very little to change your party registration. Have your voter registration card or driver's license number ready, along with your name, address, and date of birth as they appear on your voter registration. If you are changing your registration by mail, you will need to sign the form.

If you do not have your voter registration number, the election office can look you up by name and address. Some online portals ask for the last four digits of your Social Security number to verify your identity, though this varies by state. You do not need a new ID, proof of residence, or any other documents.

Timing: when the change takes effect

Online changes usually take effect immediately or within one to three business days. Mail submissions typically process within one to four weeks, depending on how busy the election office is. In-person changes at the election office or DMV take effect the same day.

Your new party registration will be active in time for the next primary election if you change it before the registration deadline for that primary. Each state sets its own primary deadline — some close registration 15 days before the primary, others 30 days before. Check your state election office website for the specific deadline in your area.

How party registration affects voting in primaries

Party registration determines which primary ballot you receive in states with closed primaries. If you are registered as a Democrat, you vote only in the Democratic primary. If you are registered as a Republican, you vote only in the Republican primary. If you are registered as unaffiliated or independent, you cannot vote in either party's primary in a closed primary state.

States with open primaries let you vote in whichever primary you choose on election day, regardless of your registration. States with semi-closed primaries let unaffiliated voters choose which primary to vote in, but registered party members can vote only in their own party's primary. Your state election office website will tell you which system your state uses.

Party registration does not affect general elections. In November, all registered voters receive the same ballot and can vote for any candidate, regardless of party registration.

Changing your registration before a primary election

If you want to vote in a primary election, change your registration before your state's registration deadline for that primary. Deadlines vary widely — some states close registration 15 days before the primary, others 30 days before, and a few allow same-day registration. Missing the deadline means you cannot vote in that primary, but you can still vote in the general election in November.

If you change your party registration after the primary deadline has passed, your new registration will take effect for the next primary election. You can still vote in the general election as a registered voter, but you will not be able to vote in the primary that has already closed.

Changing back or switching to a different party

You can change your party registration as many times as you want. There is no waiting period, no fee, and no penalty for switching. You simply go through the same process again — online, by mail, or in person — and select your new party or unaffiliated status.

Some states have a waiting period before you can change your registration again, but this is rare and usually only applies if you changed your registration very recently. Most states let you change immediately. If you are unsure whether your state has a waiting period, call your election office or check their website.

What happens if you do not register with a party

You do not have to register with a political party. You can register as unaffiliated, independent, or no party preference — the exact term depends on your state. Unaffiliated voters can vote in general elections just like party-registered voters.

In closed primary states, unaffiliated voters cannot vote in primary elections. In open or semi-closed primary states, unaffiliated voters can vote in whichever primary they choose. Some states let unaffiliated voters request a primary ballot from either party on election day.

Frequently Asked Questions

Does changing my party registration affect my voter registration?

No. Party registration and voter registration are separate. Changing your party does not change your voter registration status, your address on file, or your right to vote. You remain registered to vote in your precinct regardless of which party you are registered with.

Can I change my party registration on election day?

It depends on your state. Some states allow same-day party registration changes, while others require you to change before the registration deadline. Check your state election office website for the deadline in your area. If you miss the deadline, you can still vote in the general election but not in that primary.

Will changing my party affect my taxes or government benefits?

No. Party registration is a voting matter only. It does not affect taxes, benefits, employment, or any other government services. Your party registration is public record in most states, but it has no legal consequences outside of voting.

What if I move to a different state?

You must register to vote in your new state, and you can choose your party registration at that time. Contact your new state's election office or register online through your new state's voter registration portal. Your old registration will be cancelled once you register in your new state.

How do I find my state election office?

Search "[your state] secretary of state" or "[your county] election office" online. Most state election offices have a website with links to county election offices, voter registration forms, and primary deadlines. You can also call your county clerk's office or local DMV for information about changing your party registration.
