How to Find an old Friend's Phone Number for Free

Online
1. Begin your search in the online white pages. If you know what city or ZIP code your friend lives in, you can enter their name and see what comes up. You're in real luck if you know an address. You can do a reverse search, just enter the address in the appropriate field and hit enter. The site will provide you with a phone number that corresponds to the given address.
2. Create a profile on one of the popular social networking websites and look for your friend. MySpace and Facebook are two popular choices that help reconnect people everyday. If you find your friend, you can message them and ask for a current phone number.
3. Try reunion websites. These sites are organized by the year one graduated from high school or college. You may not be able to retrieve a phone number from these sites, but you can find enough information to aid in another search.
4. Check email directories. If your friend has a Yahoo or Hotmail account, this search should bring up current contact information or, at least, an email address. Follow up with an email to the friend, and ask for a phone number.
