For an updated tutorial on how to use this site see Pagine Bianche – Italian White Pages Updated .
A great resource for looking up Italian surnames and locating people in Italy is to use the on line Pagine Bianche (White Pages). This telephone directory also links to the Pagine Gialle or the Yellow Pages so you can locate businesses.
There are a few ways to use the site. The first is to click on ricerca, then plug in the surname and or address in chi/cosa and the comune(town, city or province) name in dove if known. Another way to use the site is to click on ricercha speciale and use it to do a reverse look up if you know a phone number but don’t know who it’s registered too.
No matter how you choose to use the site it’s definitely worth checking out.
