We encourage whistleblowers and/or anyone representing a whistleblower to review our Submission guide, Award eligibility section, and Protections section of this website prior to contacting our office with any questions.

Whistleblower-only hotline

Whistleblowers, potential whistleblowers, or their lawyers can leave a message on the Whistleblower hotline voicemail. This hotline is strictly for individuals who have already submitted a whistleblower report or are serious about reporting and have a specific question about making a submission. Inquiries that do not fit this description will not be returned by our Staff. We are not able to provide details about any investigation to protect confidentiality and ensure the integrity of our process.

Calls will be returned within two business days during regular business hours. To protect your confidentiality, we will not leave a voicemail message unless the voicemail greeting clearly indicates that the phone number belongs to you.

Voicemail messages must include:

  • your full name;
  • whether you are a whistleblower or lawyer;
  • the subject of your inquiry;
  • a phone number where you wish to be reached; and
  • your Submission ID (if you have already submitted a report).
