Reverse Directories
Using reverse directories you can look up an address using a phone number. This can be very useful to find out who called you when all you have is a phone number like with caller ID. This can permit you to find out the name and address of the caller and call them back or block them from ever calling you again. There is another use for reverse directories and that is to find out the name and address of telemarketers that call or harass you. Once you have the company information and have requested that they take you off their list, you can take some action against them if they call again. Telemarking companies that keep calling you can be sued and you can collect $500 for each illegal call they make to you. You can sue them in small claims court and when they don't show up to fight your claim, you have the legal right to collect your money.
