You can find people online for free using either a people search service such as PeopleSmart, a social network like Facebook or LinkedIn, or search an online White Pages directory. If no results are found, a subscription public records search service such as Intellius may be the best option.
Finding people online can be relatively easy using the right tools for the right information. When looking for a person online it's best to start with free options that people commonly communicate on and update regularly such as social media accounts. Popular social media outlets include Facebook, Twitter and Instagram. A professional is likely to have a profile at LinkedIn.com. The type of information that may be available on social media profiles includes full name, birth dates, current city and state, relatives, friends, and photos.
People search services such as PeopleSmart are another way to find someone online and may be a good place to start if the target's social media accounts couldn't be found. An online White Pages search may also yield phone numbers and addresses not currently listed by an individual on social media.
Sometimes someone is simply hard to find online, and it's best to turn to a non-free options such as Spokeo or Intellius. These companies charge subscription fees for access to any person's public records, court documents, arrest records, known addresses and other information not listed elsewhere.
