Find out who is calling with 800 Notes.

If a number comes through on my cell phone that I don't know, I do not answer it! Instead, I grab the number (memorize it, write it down, copy/paste) and type it into 800 Notes immediately.

Sometimes, if I'm really on the ball, I even get the results before the call finishes ringing, and I can answer the call if it's someone I actually want to talk to...like the car dealership or my credit card company.

Make sure to read through several of the comments to get a good feel for the company that is calling. The first comment listed isn't always 100% correct. I usually go with the majority of responders.

If the cell phone companies would join the 21st century and introduce caller ID, the problem would be moot, but until then, I use 800 Notes. If you know of similar sites or a better way to check numbers as they come in on your cell phone, please post them in the comments.
