The Federal Bureau of Investigation relies on confidential information provided by the public to combat crime and illegal conduct. The appropriate method of reporting information to the FBI depends on the kind of activity involved. The agency provides telephone and online contacts, some reserved for reports of specific, large-scale threats or hazards.
Reports of Terrorism, Criminality or Violations of Federal Law
You can make reports to the FBI in one of two ways: through the agency's online Tips and Public Leads form, available on its official website, or by contacting a field office by phone or by email. From outside the United States, informants can contact the FBI through an international office. The FBI currently does not have a national email contact for reporting crime.
Dedicated Contact Methods for Specific Activity
The FBI has a designated toll-free number, 855-TELL-FBI, or 855-835-5324, to report suspicious activity that involves chemical, biological or radiological materials. You should report online scams and email hoaxes through the online Tips and Public Leads form or the Internet Crime Complaint Center, also online. To provide information on select major cases, call the Major Case Contact Center, which has a separate phone number, 1-800-CALL-FBI, or 1-800-225-5324.
