Where and how to change your party registration

You change your party affiliation through your state or county election office, not through a political party itself. The process is straightforward: you fill out a form, submit it in person or by mail, and your registration updates within days or weeks depending on your state's processing time. Some states let you change affiliation online through their voter registration portal.

Start by finding your local election office. Search "[your county] election office" or "[your state] secretary of state voter registration" to locate the right agency. That office handles all voter registration changes, including party switches. You do not need to contact the Democratic Party, Republican Party, or any other organization directly—they do not process these changes.

The form you need is usually called a voter registration form, party change form, or affiliation change form. Your election office website will have it available to read, or you can request one by phone or in person. Some states combine all registration updates into a single form; others have a dedicated party change document. Either way, the same office handles both.

Key Takeaways

  • Contact your county or state election office to change your party affiliation; political parties themselves do not process these changes.
  • You will fill out a voter registration or party change form and submit it by mail, in person, or online depending on what your state offers.
  • Processing typically takes one to four weeks, though some states update records within days.
  • Some states have waiting periods between when you change affiliation and when you can vote in a primary election, so check your state's rules before an election.
  • You can change your affiliation as many times as you want, and there is no fee or penalty for doing so.

What information you need to provide

The form asks for your name, address, date of birth, and driver's license or state ID number—the same information on your voter registration. You will also select your new party affiliation from a list. Most states offer the major parties (Democratic, Republican, Independent, Libertarian, Green) plus an option for "no party affiliation" or "unaffiliated."

If you have moved since you registered, update your address at the same time. Some election offices combine address changes and party changes on one form. If your name has changed, you may need to submit additional documentation like a marriage certificate or court order, but this is separate from the party change itself.

You do not need a reason to change your affiliation. Election offices do not ask why, and you do not have to explain. straightforward indicate your new choice on the form and submit it.

How to submit your change

Most states accept party change forms by mail. Print the form, fill it out, sign it, and mail it to the address listed on the form or on your election office's website. Include your voter registration number if you have it (it appears on your voter card), though the office can look you up by name and address if needed.

Many states also accept forms in person at the election office during business hours. This is the fastest route if you want confirmation that your change was received. Some election offices accept forms at satellite locations or during early voting periods.

A growing number of states offer online registration changes through their secretary of state website. If your state has this option, you can log in with your driver's license number and date of birth, update your affiliation, and submit electronically. Online changes often process within days.

Processing time and when your change takes effect

Most states process party changes within one to four weeks. Your election office will update your registration record, and you will receive confirmation by mail or email depending on what you provided. Some states send a new voter card showing your updated affiliation; others straightforward update their records without sending physical confirmation.

Your change takes effect when ready for most purposes, but there is one important exception: primary elections. Many states have rules about when you must change affiliation before voting in a primary. Some require the change 15, 30, or even 90 days before the primary election. If you change affiliation close to a primary, you may not be able to vote in that primary under your new party. Check your state's primary rules before an election if timing matters to you.

General elections (presidential, congressional, local) have no affiliation requirement, so your change takes effect when ready for those.

Changing affiliation in closed primary states

Some states only let registered party members vote in that party's primary election. If you live in a closed primary state and want to vote in a particular party's primary, you must be registered with that party before the important date—usually 15 to 90 days before the primary, depending on the state.

If you change affiliation after the important date, you can still vote in the general election, but you will not be able to vote in the primary under your new party until the next election cycle. This is why timing matters: if you want to participate in an upcoming primary, change your affiliation well before the state's important date.

Open primary states and states with semi-open primaries have looser rules. Some let you vote in any party's primary regardless of your registration, or let you change affiliation on Election Day itself. Search "[your state] primary voting rules" to see what applies where you live.

What happens if you do not change affiliation

If you do not formally change your registration, you remain affiliated with your previous party. This affects which primary ballots you receive and which candidates you can vote for in closed primary states. It does not prevent you from voting for any candidate in general elections—your affiliation is separate from how you actually vote.

Some people stay registered with a party they no longer support because they want to vote in that party's primary, or because they have not gotten around to changing. Others switch to "no party affiliation" or "independent" to avoid receiving party mail or to keep their voting choices private. There is no requirement to be affiliated with any party.

Frequently Asked Questions

Can I change my party affiliation online?

Many states offer online registration changes through their secretary of state website. You log in with your driver's license number and date of birth, update your affiliation, and submit. Not all states have this option yet, so check your state's election office website to see if it is available where you live.

How long does it take to change my party affiliation?

Processing usually takes one to four weeks by mail. In-person submissions at your election office may process faster, sometimes within days. Online submissions often process within a few days. Your election office can tell you the typical timeline for your state.

Will changing my party affiliation affect my voter registration or my ability to vote?

No. Changing your affiliation does not affect your voter registration status or your right to vote in general elections. It only changes which primary ballot you receive in closed primary states and may affect which primary you can vote in if there is a important date before the election.

Can I change my affiliation multiple times?

Yes. You can change your party affiliation as many times as you want. There is no limit, no fee, and no penalty. Some people change affiliation multiple times over their lifetime as their views shift or as they want to participate in different primaries.

What if I want to be unaffiliated or independent?

You can select "no party affiliation," "independent," "unaffiliated," or a similar option on the registration form. The exact term varies by state. This means you are not registered with any political party. You can still vote in general elections, and in open primary states you can vote in primaries too.
