And this is one of the ways to filter random scams. If a legitimate business or public entity is reaching out to contact you about an issue you need to deal with, they will know some identifying information about you. Especially the ones claiming that there’s a warrant (or will be). If that was the case, they would definitely know your name and other specific details.

That said, there are targeted scams, too, so don’t assume that if someone can tell you your name that they are legit. Ask them for a callback number (don’t call it, ask because they might be dumb enough to give you a number linked to them that you could pass on to investigators), then hang up and call the number you looked up online.
