According to the most recent US census data, as many as one in four Americans may not be registered to vote. As of 2022, there are 1.23 million residents in Bexar County that are currently registered. Let’s help add to that.

Plan ahead: The San Antonio General Election for Mayor and City Council is happening on Saturday, May 3.

Double-check your registration status

You only need to update your voter registration status when you move (otherwise your ballot gets sent to the wrong place), but it’s best to double-check to make sure everything’s correct ahead of time.

Find your registration status on the Vote Texas website and see what items will be on your next ballot. It only takes a few seconds to fill out.
