Prior to the March party primaries, officials with the Dallas County Board of Registrars mailed out more than 29,000 voter identification cards, asking registered voters in the county to either confirm their information or to send back any changes.

Two weeks after the vote, the office continues to receive hundreds of cards being returned for poor addresses. It is a problem, registrar officials say, that could lead to thousands of voters in Dallas County being moved to the inactive voter rolls.

“We are getting them in by the stacks,” Dallas County Board of Registrars member Lola Sewell said Tuesday. “We are asking those who did not get a card mailed to them, to please come in and verify or change their information.”

Sewell said she — and other registrar board members — are now working on the voter rolls in advance of the statewide runoff election on April 24. Even though there are no local races on the ballot, the office is working to enter all the changes ahead of the April 24 election, so that those who do go vote, won’t run into any problems.

As part of that effort — and as part of their work to prepare for a busy election season that includes municipal elections in August and a general election in November — the office has set a deadline of April 13 for those who need to update their voter information.

“At that point, we are likely going to start moving those voters, whose card was returned for an incorrect address, they will be moved to the inactive voter roll,” Sewell said. “That won’t prevent someone from voting, the poll workers will just have to have call our office, confirm who they are, and then they can vote.”

Sewell said voters should always update their voter information with the Board of Registrars when they move “even if they move across the street, because that could change the district they vote in or change where they vote.”

She also said anyone who has married or divorced since the last time they voted, should also update their voter identification information.

“We want to make sure the name that is on the rolls, match the one that is on the voter’s ID,” Sewell said.

The voter rolls managed by the Dallas County Board of Registrars is used for county-wide elections, general elections and municipal elections, such as city council and school board elections.

The office is located in the Dallas County Courthouse and is open Monday through Friday from 8:30 a.m. to 4:30 p.m.
