Houston Voter Registration Guide: How to Register and Vote
Date Published
Harris County has more than 2.5 million registered voters — and registering is simpler than most new residents expect. If you have a Texas driver's license or state ID, you can do it online in under five minutes. This guide covers every way to register, the deadlines that matter most, what to bring when you vote, and what to do after you move.
Am I eligible to vote in Texas?
You can register to vote in Texas if you meet all of these requirements:
- You are a US citizen.
- You are at least 18 years old on election day. (You may pre-register at 17 if you will turn 18 before or on the next election day.)
- You have been a Texas resident for at least 30 days before election day.
- You have not been declared mentally incompetent by a final judgment of a court.
- You are not a convicted felon, or your sentence and supervision are complete and your rights have been restored.
If you are moving to Houston from another state, you can register as soon as you establish Texas residency — the only timing constraint is the 30-day pre-election deadline.
The one deadline that controls everything
Texas requires you to register at least 30 days before the election you want to vote in. This applies equally to primaries, runoffs, constitutional amendment elections, and city and school board races — not just the November general election.
If you miss the deadline for one election, your registration carries forward and you can vote in the next one.
How to register: four methods
Online through Texas.gov
The fastest option. Visit VoteTexas.gov and use the online voter registration portal. You will need:
- A Texas driver's license or Texas personal ID card issued by TxDPS
- The last four digits of your Social Security number (or your full SSN if you have no TX DL or ID)
- Your current Texas address
If your information matches existing TxDPS records, the whole process takes a few minutes. Your voter registration certificate arrives by mail in two to four weeks. If you do not have a Texas-issued license or ID yet, use the mail method instead. Our driver's license and car registration guide walks through getting a Texas ID.
By mail
Download the Texas Voter Registration Application (Form VR-1) from VoteTexas.gov. Fill it out, sign it, and mail it to:
Harris County Tax Assessor-Collector & Voter Registrar P.O. Box 3527 Houston, TX 77253-3527
The form must be postmarked at least 30 days before election day. Forms are also available at public libraries and many post offices across Harris County.
In person at the Harris County Clerk
Walk in and register at the Elections Division:
Harris County Tax Assessor-Collector & Voter Registrar 1001 Preston St. Downtown Houston, TX 77002
The office is open Monday through Friday during regular business hours. Check harrisvotes.com for current hours and any satellite office locations before you go.
At a TxDPS office or state agency
Texas participates in the National Voter Registration Act (also called Motor Voter). When you apply for or renew a Texas driver’s license or ID at any TxDPS office, staff will offer to register you to vote at the same time. Say yes and DPS transmits your information to the county automatically.
You can also register through Texas Health and Human Services offices when applying for benefits, at Armed Forces recruitment offices, and at US Citizenship and Immigration Services naturalization ceremonies.
Check whether you are already registered
Go to VoteTexas.gov and click “Am I Registered?” Enter your name, date of birth, and county. The system pulls directly from the statewide voter roll and shows your registration status, precinct number, and assigned polling location for upcoming elections.
This is also the fastest way to confirm your address is current after a move.
What to do when you move
Moving within Texas does not automatically update your voter registration. Your options:
- Submit a new Texas Voter Registration Application with your current address — this also serves as an official address change.
- Update online through Texas.gov if you have a TX DL or ID.
Harris County allows registered voters who have moved within the county to cast a “limited ballot” for county-wide and statewide races even if their address was not updated in time, but that is a fallback, not a plan. The cleanest approach: update your registration whenever you update your driver’s license or when you notify the US Postal Service of your move.
If you are also working through your Houston utilities setup or property tax exemption after a move, add voter registration to that same to-do session.
What to bring when you vote
Texas requires a photo ID to cast a regular ballot. Accepted IDs:
- Texas driver’s license or personal ID card (not expired more than four years)
- Texas handgun license
- US military ID with a photo
- US passport (book or card)
- US citizenship certificate with photo
- Texas Election Identification Certificate (EIC), available free at any TxDPS office
If you do not have an acceptable photo ID, you can still vote. Sign a Reasonable Impediment Declaration at the polls and present one supporting document showing your name and address: a utility bill, bank statement, government document, paycheck, or check from a government entity.
Bring your voter registration certificate too. It is not sufficient ID on its own, but it lists your precinct number, which confirms your correct polling location.
Where to vote in Harris County
Harris County uses a county-wide voting center model. During early voting and on election day, any registered Harris County voter can cast a ballot at any open Harris County voting location — you are not restricted to your assigned precinct.
Find the nearest open polling location at harrisvotes.com by entering your address. The site lists all early voting sites (typically open two weeks before election day, with weekend and evening hours), election day centers, and their hours.
Vote by mail
Mail ballots are available to Harris County voters who qualify: you must be 65 or older, disabled, or away from the county for the entire voting period. Apply for a mail ballot at harrisvotes.com. Applications must be received by the county at least one week before election day. Do not wait until the last week.
The fact that surprises most newcomers
In most Texas counties, you are assigned a single polling precinct and must vote there. Harris County does it differently: it uses a county-wide voting center model, which means any registered Harris County voter can walk into any open Harris County polling location during early voting or on election day and cast a full ballot. The county runs dozens of early voting sites with extended evening and weekend hours. The practical upshot: finding a convenient place to vote is rarely the problem. Missing the 30-day registration deadline is.
How we chose
Every fact in this guide was cross-referenced against official government sources: the Texas Secretary of State’s voter registration pages at VoteTexas.gov and SOS.Texas.gov, and the Harris County Clerk’s Elections Division at harrisvotes.com. No third-party voter advocacy organizations or partisan sites were used. This keeps the guide neutral and reliable regardless of who is on the ballot.
