Your bank’s charter determines where to start: the OCC supervises national banks and federal savings associations; state-chartered banks have a state regulator and a federal supervisor that depends on whether they are members of the Federal Reserve. FDIC deposit insurance is a separate role, so an FDIC-insured bank is not necessarily supervised primarily by the FDIC. To identify your bank’s regulator, look up its full legal name and location in the FDIC’s BankFind directory, then follow the appropriate agency’s official contact route.
Which agency supervises which banks?
The main distinction is the bank’s charter. National banks and federal savings associations are federally chartered and supervised by the Office of the Comptroller of the Currency (OCC). State-chartered banks are supervised by their state banking regulator as well as a federal agency. Their primary federal supervisor depends on Federal Reserve membership.
| Bank type | Primary federal supervisor | State role | Important distinction |
|---|---|---|---|
| National bank | OCC | The cited OCC guidance does not identify a state banking regulator as its chartering regulator. | FDIC insurance, if applicable, does not make the FDIC the primary supervisor. |
| Federal savings association | OCC | It has a federal charter and OCC supervision. | Deposit insurance is a separate function. |
| State-chartered bank that is not a Federal Reserve member | FDIC | State banking regulator also supervises. | A state charter does not mean state-only supervision. |
| State-chartered bank that is a Federal Reserve member | Federal Reserve | State banking regulator also supervises. | FDIC insurance does not make the FDIC the primary federal supervisor. |
The OCC says that “National banks and federal savings associations are chartered and regulated by the Office of the Comptroller of the Currency.” The OCC’s financial institution lists identify institutions it charters and regulates; the lists are identified as active as of August 31, 2026. For state-chartered banks, the FDIC describes itself as the primary federal regulator when the bank does not join the Federal Reserve System. The FDIC’s description of its responsibilities also distinguishes that supervisory role from deposit insurance.

How to look up your bank’s regulator
- Find the exact institution name and location. Use a statement, card, or the bank’s official website. A familiar brand or bank-family name may not be the legal name of the institution holding your account.
- Search the FDIC BankFind Institution Directory. Look for the bank by its full name and location, and check its listed primary supervisor. The FDIC’s consumer complaint guidance specifically directs customers to BankFind to identify a bank’s regulator.
- Check OCC lists if it appears to be an OCC-chartered institution. Use the OCC’s Financial Institution Lists to check whether the institution is a national bank or federal savings association.
- For a state-chartered bank, note both regulators. Record the state banking regulator and the federal supervisor shown for the institution. The OCC’s institution-list page links to the Conference of State Bank Supervisors directory to find state banking department websites.
- Use the identified agency’s official complaint or consumer-assistance contact. The OCC provides assistance for customers of national banks and federal savings associations; the FDIC’s consumer guidance provides a regulator-identification and agency-contact route.
Why FDIC insurance does not identify your regulator
Deposit insurance answers whether eligible deposits are protected under the FDIC insurance system; it does not, by itself, tell you which agency is the bank’s primary federal supervisor. As the FDIC puts it, “While the FDIC may insure the funds at your bank, the FDIC may not be your bank’s federal regulator.” A state-member bank, for example, can have FDIC-insured deposits while the Federal Reserve is its primary federal supervisor and its state agency also supervises it.

Choosing the right office for a complaint
Start with the institution lookup, then use the contact route provided by the regulator identified for that bank. The OCC’s customer-assistance route covers national banks and federal savings associations. For other banks, the FDIC’s consumer complaint information explains how to identify the regulator and reach the relevant agency. The appropriate office can depend on the institution and the issue, so do not assume one federal agency handles every bank complaint.
These lookup steps apply to banks. They do not establish regulator assignments for credit unions, nonbank lenders, bank holding companies, or fintech brands that partner with a bank. If the name on an app or card is not the legal name of the bank, use the bank’s official disclosures or account materials to identify the institution first.

Federal Deposit Insurance Corporation
The FDIC insures deposits and is the primary federal regulator of state-chartered banks that are not members of the Federal Reserve. Insurance and supervision are distinct functions; the bank’s charter and, for state-chartered banks, Federal Reserve membership determine the supervisory route.
Rank #3
Federal Reserve and state banking regulators
The Federal Reserve is the primary federal supervisor for state-chartered banks that are Federal Reserve members. State banking regulators also supervise state-chartered banks. State agency names and contact processes vary, so use the state directory rather than assuming each state uses the same office name or complaint procedure.
