Indicators of Human Trafficking

Recognize the Signs

Human trafficking victims are often overlooked, because people do not recognize the indicators of human trafficking. When travelers and transportation employees know what to look for, they can serve as a community's eyes and ears. Recognizing indicators of human trafficking is the first step in identifying potential victims.   

Human trafficking victims can be of any age, sex, race, ethnicity, ability, sexual orientation, socioeconomic background, religion, national origin, education level, or citizenship status. Rather than being motivated by any single identity or demographic, human trafficking indicators identify objective signs that could indicate potential criminal activity.  

General Indicators of Human Trafficking

Note that:  

  • All indicators listed below are not present in every human trafficking situation.
  • It is important to recognize that many trafficking indicators may not be visible to the general public or the transportation workforce, as their interactions with potential victims are often brief and situational compared to more sustained engagement with other frontline professionals.
  • The presence or absence of any of the indicators is not necessarily proof of human trafficking.
  • Some at risk individuals may be traveling alone.
  • While no single indicator can confirm a human trafficking situation, several combined indicators may increase the likelihood that a person is actively being targeted, recruited, and/or exploited.    

If you notice something, don’t dismiss the feeling. Trust your instincts.
