Report Fraud Hotline

Identity thieves may spoof Hotline telephone numbers to make it appear as if calls are coming from the OIG hotline when in fact they are not.
  • Do not provide any personal information to unknown callers.
  • If you receive a call from someone identifying themselves as a member of the OIG Hotline, OIG employees will provide their name, a callback number and the Report Number provided when you originally contacted the OIG Hotline.
  • If not, ask for their name, hang up, and immediately call the OIG Hotline at (800) 424-9071 to report the incident.

Report Fraud, Waste & Abuse

The Office of Inspector General (OIG) maintains a Hotline for receiving allegations of fraud, waste, abuse, or mismanagement affecting U.S. Department of Transportation (DOT) programs or operations. Allegations may be reported 24 hours a day, seven days a week by DOT employees, contractors, or the general public. Download Fraud Awareness Posters for your workplace.

Please provide relevant and specific details of your complaint, including the identity of the person, company, or organization alleged to have engaged in wrongdoing; a description of the alleged impropriety; the DOT facility, funds or program affected by the allegation; any relevant contract numbers; date(s) of alleged wrongdoing; how you are aware of the alleged impropriety; the identity of potential witnesses; and the identity and location of supporting evidence or documentation. NOTE: The OIG Hotline is obligated to expeditiously forward all safety-related complaints to DOT’s safety regulatory agencies.

Allegations with limited specificity or merit may be held in abeyance until further, specific details are reported.

Can I Remain Anonymous?

Yes, you may remain anonymous. However, we encourage you to identify yourself in the event additional questions arise as we evaluate or pursue your allegations. Please consider providing your name and contact information to allow for follow-up contact if needed. In many cases, our inability to reach you for follow-up may prevent a comprehensive review of your complaint.

How Will My Confidentiality Be Protected?

The Office of Inspector General will protect the identity of complainants to the maximum extent possible by law. Confidentiality is established by Section 7(b) of the Inspector General Act of 1978, which precludes the IG from disclosing the identity of a DOT employee who reports an allegation or provides information, without the employee's consent, unless the IG determines that disclosure is unavoidable during the course of the investigation. Non-Department of Transportation employees who report allegations may specifically request confidentiality.
