What We Don't Like Usually must know the person's birthday. Might work only in the US, and in certain states only. Might be outdated if they haven't voted recently. A little known fact is that you can find someone's home address using just their name and birthday. This is possible by looking up the person's voter registration information. Some states consider vote registration information public record, and if the state has an online tool for finding this information, all you need to do is enter a few details about the person. For example, if you know the person lives in Kansas, Kansas Secretary of State | VoterView lets you see their home address using their name and birthday. Other states should work similarly, but it's possible you'll need details other than their birthday, or their address might not be public. Was this page helpful? Thanks for letting us know!
