If you get a lot of annoying phone calls from pranksters or if you've ever been harassed by someone on the telephone and you want to find out who is making all those calls you can try out the CallerBase.com service. It's also great if you want to find out who those pesky telemarketers are or if you've just missed a phone call and don't want to call back because you're not sure who it is, this service will help you find out. I know I receive many calls on my phone and my cell phone that I don't want to answer because I'm not sure who is calling so this would be a great service to try out. It's a reverse phone database that searches telephone numbers for you and let's you know who is calling. Their database will search out cell phones and landline telephones within the United States and Canada and give you information such as the name, address, city, state of the person who called -- all great information to have if you're trying to track down any of these type of bothersome calls.
