Chances are your phone is set up to not accept calls that do not have caller ID. But every so often you get a call from a number from an area code you’ve never seen before. Of course, you don’t answer it, but you’re left wondering, "Who was that?"

Most of the time it’s a marketing call, but it is important to find out who called so you can contact the appropriate people to opt out of the marketing.

There are two sites you can use to get this information, 800Notes and whocalled.us.

I find 800Notes to be the better of the two.

To note, if you want to submit a report of your own for one of these odd calls, type in the number at the top and fill out the comment form at the bottom. No registration is required.
