How can I find a friend's address if not listed in the white pages?

Question

Does anyone know how I can look up an address that is not listed in the white pages? Her name will not come up with anything and I need to notify this friend of some important news.Is there another way to find her?

Thank you all so much

Answer 1

If you know her phone number you can do the reverse directory or sometimes a people search if you know her e-mail address.

I found one once for genealogy just because her maiden name (she hyphenated) was unusual. I knew absolutely nothing else about her.

Outside of that all I know is a paid people search.
