One in nine voters in Harris County is “in suspense,” which signals a question about the address on their record, according to records obtained by the Defender from the Harris County Tax Assessor-Collector & Voter Registrar’s office. This does not mean that they have lost the right to vote or that they were removed from the rolls. Texas has used the suspense system for more than 30 years, and the number changes as voters either move or confirm their addresses by updating their information.
But it could be a deterrent for some.
“It means that they have to have that to engage in an extra step when it comes to participation,” said Brandon Rottinghaus, a political analyst and professor in the Department of Political Science at the University of Houston. “There’s a risk that this could either make people think they’re not able to vote, which means they won’t vote. Or it could mean that the extra burden of facilitating the vote is too much for them, and the cost is too high, so they choose not to vote. People can still participate, but it’s just a question of whether or not they feel like they are a part of the system, and this notification could potentially increase the likelihood that those folks won’t vote.”
What the data says
In Harris County, 2.4 million voters are in “active” status, while more than 319,000 are “in suspense,” records show.
The voters whose registrations are in suspense can still vote. It means that county officials have reason to believe the voter may no longer live at the address on their registration, according to the Texas Secretary of State’s office. This happens when a voter registration certificate, jury summons, mailing, or other official correspondence is returned as undeliverable. At the polls, a suspense voter can still vote after completing a statement of residence confirming their address.
However, under Texas procedures, a voter who fails to update or confirm an address and remains on the suspense list through two elections for state or county offices can have their registration canceled.
Rottinghaus explained that the region’s mobility could contribute to the change in registration status.
“Texas has an enormous population mobility,” Rottinghaus said. “It helps explain why it’s the case that you see so many suspense voters and makes them politically consequential. Texas has experienced tremendous migration and population growth, especially in metropolitan areas. People moving between apartments, neighborhoods, and counties will inevitably create registration address mismatches. A huge population turn might mean that you’ve got more suspense voters.”
If the suspense voters are disproportionately younger, Latino, Black, or renters, or people who have been constantly moving, it is harder for the parties to turn those voters out, he added. But movement alone does not account for every record in the files, nor does it establish how many voters have moved.
There is no racial breakdown in the data, which does not establish which demographic groups are over- or underrepresented in the suspense list.
What the Harris County data shows:
- Most are in Houston: 213,290 records list Houston as the city. Spring (18,457), Katy (16,923), Cypress (13,644), and Humble (12,315) follow.
- Suburban ZIP codes lead: The two ZIPs with the most suspended voters are 77449 in Katy (7,811) and 77433 in Cypress (7,525). The top Houston ZIP is 77084, with 7,062 names.
- Suspended voters skew young: The median birth year is 1987, which makes the median voter about 39. About 61% are under 45, and 36% are under 35. Only 13% are 65 or older.
- Many registered recently: About 44% registered in 2020 or later.
- Recent activity is common: 138,304 records, 43%, show last activity in 2026
What about Houston?
Out of the 319,000 voters “in suspense,” Houston comprises more than 213,000, which includes records with a Houston address designation but not a count within Houston city limits.
Of the 213,290 Houston records, 62% belong to voters under 45, and 37% to voters under 35.
The Houston ZIPs with the most suspended voters are:
- 77084
- 77004
- 77007
- 77077
- 77070
These five ZIP codes alone account for about 30,400 voters.
James Ronje, the executive director of Vote Houston, said his organization works through groups in local communities to turn out the vote.
“While the message is very important, the messenger is also very important,” said Ronje, whose goal is “for people to have accurate information so that they can have their voice heard, and so if that means that that message comes from somebody else, but we’ve supported it, then that’s a win in my book.”
Shevann Steuben, vice president of the National Association for the Advancement of Colored People (NAACP) Houston chapter, on the other hand, emphasized practical knowledge.
“Civic participation is making sure that you’re registered,” Steuben said. “Make sure you know how to find your sample ballot. Make sure you know how to research what is on your sample ballot, whether that is a constitutional issue, a constitutional amendment, or an actual candidate that you know how to represent.”
Being civically engaged also involves being knowledgeable about candidates and the issues they are running on, she added.
Checking records before voting
Look yourself up: Voters can check their status and address on “Am I Registered?” at VoteTexas.gov.
They can search using one of three methods, including their:
- Voter Unique Identifier, or VUID, found on their voter registration certificate
- Texas driver’s license number, if it was provided when they registered
- First and last name
They can also contact the voter registrar’s office in the county of residence.
“There’s a risk that this could either make people think they’re not able to vote, which means they won’t vote, or it could mean that the extra burden of facilitating the vote may be too much for them and the cost too high, so they choose not to vote.”

If the record says suspense or shows an outdated address, the state provides an online registration update portal. If a voter still appears as “suspense” at a Harris County vote center, they should ask an election worker about the Statement of Residence.
Harris County says its voter information may display “SOR Required” when that form is needed.
The registration deadline for the Nov. 3 election is Oct. 5. Early voting runs from Oct. 19 through Oct. 30, with polls open 7 AM to 7 PM (barring Oct. 25, 2026: 12 PM to 7 PM).
