Warning: you will get texted so use your disposal number.
With all the news about citizens discovering their voter status has been lapsed, and new rules for being a voter, everyone should check.
But also, sometimes you forget. I have new neighbors who finished moving a month ago, and when I asked if they changed their mailing address and checked their voting status, we discovered they weren't.
Here in Brazil everybody HAS to register when turning 18. The registration can get suspended if you miss an election without justification, but you get a fine for each time.
