If you have caller ID on your landline telephone, it is going to display all of the contact person's information, especially if the call is being placed from another landline. However, when using a cell phone, the number of the line is the only information displayed. If you are curious as to the actual address of the landline calling you there is a way to find the address, simply off the given phone number.
Open up your Internet browser and navigate to WhitePages.com. This site is free to use and provides reverse lookups. This allows you to enter in a telephone number and receive information in regard to the individual with the number.
Type in the complete number in the "Reverse Phone Number" bar and click "Find."
Look over the results. At the top of the page, it states the full address of the phone number and the individual's name.
Scroll to the bottom of the page. It states the individual's exact age and offers you the ability to look up more information in regards to the person (although this information does cost extra).
