Complaint Hotline

Every day, Interior employees and private citizens from across the Nation reach out to OIG, and the information they share can turn into investigations, inspections, evaluations, or audits with outcomes that result in positive change for the Department, its employees, and the public. There is a lot at stake when wrongdoing and mismanagement occur. You are the first line of defense, and your actions matter. Our mission is to provide independent oversight and promote integrity and accountability by working with the people who contact us.

Anyone with knowledge of fraud, waste, abuse, misconduct, or mismanagement involving the U.S. Department of the Interior should contact the Office of Inspector General's hotline.

If you wish to file a complaint, please click here to initiate the hotline complaint process:
