If you have somebody's home address and want to find out his phone number, you can use a reverse-address directory. Reverse-directory books specific to different states are available for purchase, but there's no point in purchasing the directories when you can find all the information online. There are many websites that let you perform this search without any fee. However, you will only be able to get the person's home phone number and not the cell phone number, as cell phone numbers are not typically associated with addresses.
Go to a website like WhitePages, PhoneNumber, Address, SearchBug or IAF. All these sites let you search for phone numbers by address.
Type in the person's address in the respective field on the page. Under the "Address"/"Reverse Address" tab, you will be required to provide the complete address along with the city, state and Postcode. On website like PhoneNumber, you will find separate fields for "Street Number" and "Street Name."
Wait for the website to run a search through its database. The website will then show you the results, which will contain the person's name as well as phone number.
