[Hidden-tech] Where do you look up a phone number?

[Deborah Chandler]

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
