Contact the Office of Anticorruption and Integrity (OAI) to report concerns or evidence that corruption, fraud, coercion, collusion, abuse, conflict of interest, or obstructive practice may have occurred or is occurring related to any ADB-financed activity. You may report allegations to OAI by email, facsimile (fax), mail, in person, or by telephone. Only OAI staff can access any such communication.
Allegations may be reported with attribution or anonymously. However, anonymous reports are much harder to investigate as it may be more difficult to ascertain the truth, anyone making an allegation is encouraged to provide some means that will allow OAI to communicate with him or her.
Information concerning the identity of a complainant is strictly controlled and will not be released to other ADB staff or to anyone outside ADB without the consent of the complainant.
To report allegations, please provide as much information and detail as possible, including who, what, when, where, why, and how. For example
If you have documents, photographs, or other physical evidence of the alleged fraud or corruption, please send that information to OAI, either with your report or separately.
ADB offers whistleblower and witness protection.
