How to File a Complaint

Complaints must be in writing and addressed to the Complaints Receiving Officer (CRO). You may follow the format of the sample complaint letter below or simply fill out the complaint form.

You can submit these documents using any of the following contact details:

Complaints Receiving Officer, Accountability Mechanism ADB Headquarters, 6 ADB Avenue, Mandaluyong City 1550, Metro Manila, Philippines   (+632) 632-4444   (+632) 632-4442   amcro@adb.org   Complaints Submission Form

You may also hand deliver your letter to any ADB resident mission or the Complaints Receiving Officer at ADB Headquarters. Complaints may be submitted in any of the official or national languages of ADB's developing member countries.

Once your complaint is received, the Complaints Receiving Officer will acknowledge and register your complaint; clarify your complaint (if needed); provide information about ADB's Accountability Mechanism; and based on your choice of function, will forward the complaint either to the Office of the Special Project Facilitator (problem-solving function) or the Office of the Compliance Review Function.
