For a landline, I still use the old-fashioned approach: the phone book. For reverse lookup, I start with Google; most businesses can be identified that way. If it's a private number, there are several apps that can get you closer, but they cost; I know there are one or two free apps, but I've forgotten what they're called. And by "free reverse phone lookup," some apps mean "after paying one fee, your lookups are free and unlimited."

Hi all, If you wanted to either look up someone's residential landline phone number or do a reverse search on a phone number you have, which online directory/ies would you use? I know I can Google this info, but I have a very specific reason to take an informal survey here, based on existing usage trends. Thanks, Deb
