4 tools, free ones first

Each one opens the tool's own site. Free tools cost nothing; freemium tools show some results free and charge for the rest. Licensed PI items need a licensed investigator.

What to expect

What you can find for free

  • Every site where the username is taken, from WhatsMyName or Sherlock
  • Direct links to the profile on the major platforms
  • Mentions of the handle anywhere on the web

Where free tools stop

A matching username isn't proof it's the same person. Connecting accounts, aliases and real names, and documenting them so they hold up in court, is a social media workup by a licensed investigator.

Tips

  • People reuse handles. Try variations with the numbers or underscores removed, and the part of their email before the @.
  • Save dated screenshots as you go. Profiles get deleted or made private quickly.
