File a Complaint

If you have a problem with your national bank or federal savings association, and want to submit a complaint, the Office of the Comptroller of the Currency's (OCC) Customer Assistance Group may be able to help. The OCC regulates national banks and federal savings associations.

Some issues that we cannot help with are:

  • Give legal advice;
  • Act as a court of law or as an attorney on your behalf;
  • Become involved in matter that has been litigated or is being litigated;
  • Advocate for either party; or
  • Seek monetary compensation.

Follow the steps below to learn about our complaint process.

1. Before You File

  • Try to resolve your issue directly with your bank first.
  • Check our Help Topics page to see if any of the topics address your issue.

2. Check to Make Sure We Regulate Your Bank

We can only assist customers of national banks and federal savings associations regulated by the Office of the Comptroller of the Currency (OCC), and we can only assist with areas under our supervisory jurisdiction. There are other types of banks that are regulated by other agencies. It is important to make sure that your bank is regulated by the OCC before seeking our assistance.

Who regulates my bank?

If the OCC does not regulate your bank, please file your complaint with one of the following agencies, as appropriate:
