Step-by-Step Guide

Step 1: Confirm Your Voter Registration Status

Before you can vote, you must be a registered voter in Maricopa County. Registration is not automatic — even if you’ve voted before, changes in address, name, or citizenship status require updates. The first step in the 2025 voting process is verifying your registration status.

Visit the official Maricopa County Elections Department website at www.maricopa.gov/vote. Click on the “Check Your Voter Status” tool. You’ll be prompted to enter your full legal name, date of birth, and either your Arizona driver’s license number or the last four digits of your Social Security number. The system will instantly display your registration status, current address, precinct, and party affiliation (if applicable).

If your status shows “Inactive,” it means your mail was returned as undeliverable — often due to a recent move. You can reactivate your registration online by updating your address. If you’re not registered at all, you can complete the process online if you have an Arizona driver’s license or state ID. Otherwise, you must submit a paper form, which can be downloaded from the same site or picked up at public libraries, post offices, or the County Recorder’s Office.

Deadline: All registrations must be finalized by 11:59 p.m. on the 11th day before Election Day. For the 2025 elections, the registration deadline is expected to be Thursday, October 9, 2025. After this date, you cannot register online or by mail. However, same-day registration is available during early voting and on Election Day at designated vote centers.

Step 2: Choose Your Voting Method

Maricopa County offers three primary ways to vote: mail-in ballot, early in-person voting, and Election Day voting. Each method has distinct advantages and timelines.

Mail-In Ballot (Vote by Mail) — This is the most popular method in Maricopa County, with over 75% of voters choosing this option in recent elections. All active registered voters will automatically receive a ballot in the mail approximately 27 days before Election Day. You do not need to request one unless you are newly registered after the mailing cycle begins. Once received, fill out your ballot using a black or blue pen, sign the envelope where indicated, and return it. You can mail it back (postage paid), drop it in an official drop box, or deliver it in person to any vote center.

Early In-Person Voting — Starting 27 days before Election Day, the county opens more than 100 early voting locations across its 14 municipalities. These vote centers operate Monday through Saturday, with extended hours (often 9 a.m. to 5 p.m., with some open on Sundays). You can vote in person at any location, regardless of your precinct. This method allows you to receive immediate assistance if you have questions about your ballot, make corrections, or need a replacement ballot. You can also update your address or registration status on-site during early voting.

Election Day Voting — On Tuesday, November 4, 2025, all vote centers will be open from 6 a.m. to 7 p.m. You must vote at your assigned precinct unless you are using a vote center that offers same-day registration. Your precinct is listed on your voter registration confirmation. If you go to the wrong location, you may be directed to the correct one or offered a provisional ballot.

Step 3: Receive and Review Your Ballot

Once your mail-in ballot arrives, open it carefully. The envelope contains three items: your ballot (a folded paper with printed choices), a secrecy sleeve, and a declaration envelope with your voter information and signature line.

Review your ballot thoroughly. It will include federal, state, county, and local races, as well as ballot propositions. Maricopa County uses a nonpartisan ballot design, meaning party affiliations are not listed next to candidates unless they are running in partisan races. Ballot measures will be clearly labeled with titles, summaries, and fiscal impacts.

Use the official Voter Information Guide, mailed alongside your ballot or available online at www.maricopa.gov/vote/voter-guide, to research candidates and measures. This guide includes candidate statements, nonpartisan analyses, and endorsements from civic organizations.

Step 4: Complete Your Ballot Correctly

Follow these rules when filling out your ballot to ensure it is counted:

• Use a black or blue ink pen — pencils or other colors may not be read by scanning equipment.
• Fill in the oval completely — partial marks or arrows may be rejected.
• Do not write additional comments or marks outside designated areas — this can invalidate your ballot.
• Vote in every race you wish to participate in. You are not required to vote in every contest.
• If you make a mistake, do not use correction fluid. Instead, contact the Elections Department immediately for a replacement ballot. You can request one by phone, online, or in person.

After completing your ballot, place it inside the secrecy sleeve. Then insert the sleeved ballot into the declaration envelope. Sign and date the envelope — your signature will be compared to the one on file. Unsigned ballots will not be counted.

Step 5: Return Your Ballot

There are three secure methods to return your completed ballot:

1. By Mail — Postage is prepaid. Drop your ballot in any U.S. Postal Service mailbox. To guarantee delivery, mail your ballot at least 7 days before Election Day. Ballots postmarked by Election Day but received after are still counted if received within 7 days.
2. Official Drop Boxes — Over 300 secure, 24/7 drop boxes are located throughout the county at libraries, government buildings, and community centers. These are monitored by surveillance and emptied daily by election officials. Find your nearest drop box using the interactive map on the Maricopa County website.
3. In Person at a Vote Center — You may drop off your ballot at any early voting location or Election Day vote center. This is the most reliable method, as you receive a receipt confirming your ballot was accepted.

Ballots must be received by 7 p.m. on Election Day to be counted. Ballots postmarked on or before Election Day and arriving within 7 days are valid under Arizona law.

Step 6: Track Your Ballot Status

After returning your ballot, monitor its status to ensure it was received and counted. Visit www.maricopa.gov/vote/tracking and enter your name and date of birth. The system will show you when your ballot was mailed, received, processed, and counted.

If your ballot is flagged for a signature discrepancy, you will receive a notification by mail or email (if you’ve opted in). You have until 5 p.m. on the Friday after Election Day to cure the issue by submitting a signed affidavit and a copy of your ID. This process is straightforward and can be completed online or in person.

Step 7: Confirm Your Vote Was Counted

Once your ballot is marked as “Counted” in the online system, your vote is official. You may also receive a confirmation email if you signed up for voter notifications. For added assurance, you can request a copy of your ballot record from the County Recorder’s Office. All ballots are subject to post-election audits, and results are publicly available on the county’s election results portal.

Best Practices

Successful voting in Maricopa County 2025 requires more than just knowing the steps — it demands strategic planning and attention to detail. Here are the best practices that ensure your vote is counted without delay or error.

Plan Ahead — Don’t Wait Until the Last Minute

Maricopa County sees massive turnout during peak voting periods. Mail-in ballots mailed within the final 72 hours often experience delays. Drop boxes fill up quickly in high-traffic areas. Early voting centers become crowded in the final week. To avoid stress and ensure your ballot is processed on time, complete your voting by the end of October. Set a personal deadline — such as October 25 — to finish all steps.

Update Your Address Immediately

If you’ve moved since the last election — even within the same city — update your voter registration. Voting in the wrong precinct may result in receiving an incorrect ballot or being asked to vote provisionally. Your ballot must reflect your current residence to ensure you vote on the correct local races and measures.

Verify Your Signature

Signature matching is a critical step in ballot validation. Your signature on the ballot envelope must match the one on file with the Motor Vehicle Division or your original registration form. If your signature has changed significantly (due to injury, illness, or aging), submit a signature update form to the County Recorder’s Office. This can be done online or by mail.

Use Official Resources Only

Be cautious of unofficial websites, social media ads, or text messages claiming to help you vote. Only trust information from www.maricopa.gov/vote, the Arizona Secretary of State’s site, or official county communications. Scammers often mimic legitimate sites to collect personal data or spread misinformation.

Bring Identification to In-Person Voting

While mail-in voters do not need to show ID, in-person voters (including those voting early or on Election Day) must present one of the following: Arizona driver’s license, Arizona state ID, tribal ID, U.S. passport, or two forms of secondary ID (such as a utility bill and a bank statement with your name and current address). Keep these documents in your voting folder.

Vote on All Races — Even the Lesser-Known Ones

Local races for school board, city council, and judicial positions often have the most direct impact on daily life. These races typically have lower turnout, meaning your vote carries more weight. Use the Voter Information Guide to research candidates’ platforms and voting records.

Prepare for Long Lines

On Election Day, some vote centers — particularly in urban areas like Phoenix, Mesa, and Tempe — may experience wait times of 60 to 90 minutes. Plan to vote during off-peak hours: early morning (6–8 a.m.) or late afternoon (4–6 p.m.). Bring water, a book, or a mobile device to pass the time.

Know Your Rights

You have the legal right to vote without intimidation, discrimination, or obstruction. If you encounter any issues — such as being turned away, questioned about eligibility without cause, or denied a ballot — you may request a provisional ballot and report the incident to the Maricopa County Elections Department. All voters are protected under the Voting Rights Act.

Example 1: Maria R., First-Time Voter in Phoenix

Maria, 19, just turned 18 and registered to vote online using her Arizona driver’s license. She received her mail-in ballot on October 7, 2025. After reviewing the Voter Information Guide, she decided to vote for a school board candidate who supported after-school STEM programs — a cause she’s passionate about. She filled out her ballot on October 15, placed it in the secrecy sleeve, signed the envelope, and dropped it in a drop box near her university campus on October 20. She tracked her ballot online and saw it was marked “Counted” on November 6. Maria says, “I didn’t know my vote mattered until I saw how close the school board race was. I’m proud I participated.”

Example 2: James T., Elderly Voter in Glendale

James, 76, has voted by mail for 30 years. After moving to a new apartment in Glendale in August, he forgot to update his registration. When his ballot arrived at his old address, he called the Elections Department. A representative helped him update his address online and requested a replacement ballot. He received it on October 18, voted in person at the Glendale Public Library vote center on October 25, and received a receipt. “They made it easy,” he said. “I didn’t have to wait in line, and the staff was patient with me.”

Example 3: Priya K., Non-English Speaker in Mesa

Priya, a native Urdu speaker, moved to Mesa from India in 2023. She registered to vote in May but was unsure how to understand the ballot. She visited the Mesa Public Library, where a volunteer from the Arizona Civic Engagement Collaborative helped her use the multilingual ballot preview tool. She received her ballot in English and Spanish and used a phone translation app to review the judicial races. She dropped her ballot in a drop box on October 30. “I didn’t feel lost,” Priya said. “I knew exactly who I was voting for.”

FAQs

Can I vote if I’m not registered yet?

Yes — but only during early voting or on Election Day. Maricopa County allows same-day registration at any vote center. You must provide proof of identity and residency (such as a utility bill or lease agreement) and complete a registration form on-site. Your ballot will be processed as a provisional ballot and verified within 7 days.

What if I make a mistake on my ballot?

If you accidentally spoil your ballot, contact the Elections Department immediately at 602-506-1511 or visit any vote center. You can request a replacement ballot, which will void your original. You may only receive one replacement ballot per election.

Can I vote if I have a felony conviction?

In Arizona, voting rights are restored automatically after you complete your entire sentence — including probation and parole. If you’re unsure of your status, check your eligibility at www.azsos.gov/elections/voting-rights.

Do I need to declare a party to vote?

No. Maricopa County uses open primaries for state and federal races, meaning you can vote for any candidate regardless of party affiliation. For local races and ballot measures, party affiliation is irrelevant. You do not need to register with a party to participate.

What if I’m away from home on Election Day?

Use mail-in voting. If you’re temporarily out of state (e.g., college student, military, or traveling), you can request an absentee ballot by mail. Submit a request form by October 9. If you miss the deadline, you may still vote in person at any vote center in Maricopa County if you’re present on Election Day.

Can someone else return my ballot for me?

Yes — but only under specific conditions. A family member, household member, or caregiver may return your ballot. You must sign a written authorization form, which is available on the county website. Ballots cannot be returned by non-relatives unless they are designated as authorized agents under state law (e.g., election workers).

How are ballots counted?

All ballots are processed using certified optical scan machines. Mail-in ballots are opened and scanned after Election Day, but results are not released until all in-person votes are tallied. Each ballot is audited using a risk-limiting audit, which randomly samples 2% of ballots for manual recount. Results are certified within 14 days.

What if I don’t receive my ballot?

Call the Elections Department or visit a vote center. You can request a replacement ballot or vote in person. Ballots are mailed starting September 10, 2025. If you haven’t received yours by October 1, assume it was lost and take action immediately.

Can I vote if I’m homeless?

Yes. You can register using a shelter address, park, or cross streets as your residence. You must provide a description of your location and a contact method (e.g., a friend’s address or P.O. box). The county has special outreach teams to assist unhoused voters.

Is voting accessible for people with visual impairments?

Yes. All vote centers have accessible voting machines with audio ballots, tactile interfaces, and headphone options. You can also request a large-print ballot or assistance from a poll worker. Ballots can be marked independently using assistive technology.
