Your bank’s charter is the best starting point for finding its regulator. The Office of the Comptroller of the Currency (OCC) supervises national banks and federal savings associations. State-chartered banks are supervised by their state banking regulator and by a federal agency: the FDIC if they are not Federal Reserve members, or the Federal Reserve if they are members. FDIC deposit insurance is separate from primary federal supervision, so an FDIC-insured bank is not necessarily supervised primarily by the FDIC.
Which agency regulates each type of bank?
The regulator depends first on the bank’s charter. For a state-chartered bank, Federal Reserve membership determines which agency is its primary federal supervisor. A bank’s deposit insurer is a separate question.

| Bank type | Primary federal supervisor | State banking regulator | Key distinction |
|---|---|---|---|
| National bank | OCC | No state banking regulator is identified as its chartering regulator in the OCC guidance. | FDIC insurance, if applicable, does not make the FDIC its primary supervisor. |
| Federal savings association | OCC | It has a federal charter and OCC supervision. | Deposit insurance remains separate from supervision. |
| State-chartered bank that is not a Federal Reserve member | FDIC | State banking regulator | State charter does not mean state-only supervision. |
| State-chartered bank that is a Federal Reserve member | Federal Reserve | State banking regulator | FDIC insurance does not make the FDIC its primary federal supervisor. |
The OCC says it charters and regulates national banks and federal savings associations. The FDIC is the primary federal regulator of state-chartered banks that do not join the Federal Reserve System. For a state-chartered bank, the state agency also has a supervisory role. OCC Financial Institution Lists; FDIC: What We Do.
How to find your bank’s regulator
- Get the bank’s full legal name and location. Check a statement, card, or the bank’s official website. A familiar brand or parent-company name may not be the legal name of the institution holding your account.
- Search the FDIC Institution Directory. Use FDIC BankFind to locate the institution and identify its primary supervisor. The FDIC recommends starting with the institution’s full name and location.
- Check OCC lists if the bank may have a federal charter. The OCC’s Financial Institution Lists identify national banks and federal savings associations chartered and regulated by the OCC. The lists are active as of August 31, 2026; check the current directory because institutions and listings can change.
- For a state-chartered bank, identify both regulators. Note the state banking regulator and whether the FDIC or Federal Reserve is the bank’s primary federal supervisor. The OCC page links to the Conference of State Bank Supervisors directory for state banking department contacts; agency names and contact routes vary by state.
- Use the identified agency’s official complaint route. The OCC provides customer assistance for national bank and federal savings association customers. The FDIC’s consumer complaint guidance explains how to identify a regulator and find agency contacts. The appropriate office can depend on the institution and the issue.
Why FDIC insurance does not identify your bank’s regulator
FDIC insurance protects eligible deposits at insured banks; it does not by itself tell you which agency is the bank’s primary federal supervisor. Some state-chartered banks are primarily supervised by the Federal Reserve while their eligible deposits are FDIC-insured. The FDIC explicitly cautions that it may insure funds at a bank without being that bank’s federal regulator. FDIC Consumer Complaint Process.

What to do if you cannot identify the institution
Do not rely on the brand name alone. Compare the legal institution name and location shown on your account materials with the FDIC directory. If the bank appears to be a national bank or federal savings association, check the OCC lists as well. If it is state-chartered, use the state regulator directory and note the federal supervisor shown by the FDIC lookup. Once you have the institution identified, contact the appropriate agency through its official consumer assistance or complaint page.
The OCC is an independent bureau of the U.S. Department of the Treasury. Its responsibilities include examining institutions it supervises, issuing rules and guidance, reviewing charter and branch applications, and taking corrective measures for noncompliance or unsafe practices. These agency roles provide context, but the institution-specific lookup is what identifies the right contact for your bank. OCC mission and responsibilities.
