People searches are one of the first online resources commonly used to locate friends or family member's addresses and can provide much relevant information quickly and easily. People search sites browse the Internet for records pertaining to the keywords, which means a name as well as additional information. They can return a lot of information including phone lookups and social networking sites.

Phone lookups have access to public and private directories, and can tell you not only what someone's phone number and address is, but will allow you to find out who owns a phone number. Public directories are automatically available through a people search, and can provide you with information about anyone that has a published landline listed in their name. Though this is most commonly used to find out a phone number, a people search will also return the service address registered to the phone.

If you cannot find your relative's address using the phone lookups, don't give up. There are many other existing online resources including blogs, personal webpages, and of course, social networking sites. People searches can return results from all these Internet sites, but of those, social networking sites are perhaps the most potentially useful. Social networking sites are collections of user personal profiles. Although not everyone lists their address, phone number, or other form of contact information on their social networking profile, it is very common to do so.

Of course, social networking sites and other online resources pose an additional challenge in that you may not always get a name or other personal data listed with any address or phone number you find. In this case, you can follow the phone lookup links turned up by a people search to find out who owns a phone number.
