Multiple times, I've told someone about this, and their response is, "there's no way I have any money in unclaimed funds."
(Me, typing quickly):....do you live at 123 xyz street?
Them: How did you know?!
Seriously...I try to encourage everyone to check themselves, their family, and a few neighbors and friends. ALmost guaranteed if you do that, you'll get at least one hit.
If you have a business, you can check under that, too.
