Who Calls Me is a free online service which lets you track and trace phone numbers that appear on your incoming list. Why? Well so you can find out whether that unknown caller is legit or a known phone spamming telemarketer. It’s a user generated database, which makes it even more useful…so definitely something to drop into the bookmarks.

 This is a user supplied database of phone numbers of telemarketers, non-profit organizations, charities, political surveyors, SCAM artists, and other companies that don’t leave messages, disconnect once you answer, and simply interrupt your day.
