Where to file a bank complaint depends on who regulates your bank

Your bank is regulated by one of four federal agencies, and you must file your complaint with the right one or it will be forwarded anyway—wasting time. The Office of the Comptroller of the Currency (OCC) handles national banks (they have "National" in the name or "N.A." at the end). The Federal Reserve regulates state-chartered banks that are Fed members. The Federal Deposit Insurance Corporation (FDIC) handles state-chartered banks that are not Fed members. Credit unions fall under the National Credit Union Administration (NCUA). You can find which agency regulates your bank by entering its name into the FDIC's BankFind tool or by calling the bank directly and asking.

Once you know the regulator, you have two filing routes: the regulator's own complaint system, or the Consumer Financial Protection Bureau (CFPB), which accepts complaints about any bank and forwards them to the regulator. The CFPB route is often simpler because you file once in one place, and the CFPB tracks the response. Filing directly with the regulator is faster if you want immediate escalation, but requires you to know which agency to contact.

Key Takeaways

  • Identify your bank's regulator using the FDIC BankFind tool or by calling your bank, because filing with the wrong agency delays your complaint.
  • You can file with the CFPB online at consumerfinance.gov, by mail, or by phone at 1-855-411-2372, and the CFPB will route your complaint to the correct regulator.
  • File with the regulator directly if you need faster escalation, but you must know whether your bank is regulated by the OCC, Federal Reserve, FDIC, or NCUA.
  • Include your account number, the date the problem occurred, what happened, and what resolution you want—vague complaints take longer to investigate.
  • The bank must respond to the regulator within 15 business days for most complaints, though complex cases may take longer.

What counts as a complaint the regulator will investigate

Regulators investigate complaints about unfair or deceptive practices—unauthorized charges, fees applied without disclosure, account closures without notice, failure to honor stop-payment orders, and errors in processing transactions. They also handle complaints about discrimination (denying services based on race, gender, age, or other protected status) and violations of consumer protection laws like the Truth in Lending Act or the Electronic Funds Transfer Act.

Complaints about interest rates, loan denials based on creditworthiness, or disputes over whether you owe money are not typically investigated by regulators—those are contract disputes that belong in small claims court or arbitration. Similarly, if you are disputing a transaction amount or claiming fraud, you may need to file a dispute with your bank first (which has its own timeline) before the regulator will investigate. Ask the bank in writing whether your issue qualifies as a regulatory complaint or a transaction dispute.

How to file a complaint with the CFPB

Go to consumerfinance.gov/complaint and select "Banks and credit unions" as the company type. Fill in your bank's name, the type of problem (checking account, savings account, debit card, etc.), and a description of what happened. Include specific dates, account numbers, the names of any bank employees you spoke with, and what you want the bank to do to fix it. Do not assume the CFPB knows your situation—write as if the person reading it has never heard of your bank or your account.

You can also file by mail to the CFPB at 1825 K Street NW, Washington, DC 20036, or by phone at 1-855-411-2372. Phone filing is slower because staff will take notes and submit them, but it can help if you are not comfortable writing. After you file, the CFPB sends your complaint to the bank and gives you a complaint number. The bank has 15 business days to respond to the CFPB, though they may contact you directly before that.

How to file a complaint directly with your bank's regulator

If your bank is regulated by the OCC, file at occ.treas.gov/customer-assistance/file-complaint-or-submit-feedback.html. For the Federal Reserve, go to federalreserve.gov and search "file a complaint." For FDIC-regulated banks, use fdic.gov/resources/consumers/consumer-complaints. For credit unions, file at ncua.gov/about/pages/file-consumer-complaint. Each regulator has its own form, but all require the same basic information: your name, account number, the date the problem occurred, a description of what happened, and what you want the bank to do.

Filing directly with the regulator can be faster if your complaint involves a clear violation—for example, the bank charged you a fee it did not disclose in writing. The regulator may contact the bank within days and demand a response. However, if you file with the wrong regulator, your complaint will be forwarded to the correct one, which adds a week or more to the timeline. Double-check the bank's regulator before you file.

What happens after you file

The regulator or CFPB sends your complaint to the bank within a few business days. The bank then has 15 business days to respond—either by fixing the problem, explaining why they believe they did nothing wrong, or asking for more time if the investigation is complex. You will receive a copy of the bank's response. If the bank's answer does not satisfy you, you can reply to the regulator with additional information, but the regulator will not reopen the case unless you provide new evidence.

The regulator's role is to ensure the bank followed the law, not to decide who is right in a dispute over money. If the regulator finds the bank violated a rule, they can order the bank to refund you, correct your account, or stop the illegal practice. If they find no violation, the complaint closes. You can then pursue the matter in small claims court or through arbitration if your account agreement requires it.

How long complaints take and what to do while you wait

Most complaints are resolved within 30 to 60 days, though complex cases involving multiple transactions or allegations of fraud can take several months. The CFPB publishes complaint timelines on its website, broken down by bank and by issue type—you can see how long complaints about your specific bank typically take. While you wait, keep records of all communication with the bank: emails, letters, call dates, and the names of staff members you spoke with. If the bank contacts you directly to resolve the complaint, respond in writing (email is fine) so you have proof of what was said.

If the bank closes your account while a complaint is pending, that does not stop the investigation. However, if you need access to your money, ask the bank in writing to keep the account open during the complaint process, or open a new account at a different bank immediately. Do not wait for the complaint to resolve if you need your funds.

When to file a dispute instead of a complaint

If you are disputing a specific transaction—a charge you did not authorize, a transfer that went to the wrong account, or a deposit that never posted—file a transaction dispute with your bank first, not a complaint with the regulator. Disputes have their own timeline: the bank must investigate within 10 business days for debit card transactions or 30 days for ACH transfers and checks. If the bank finds the transaction was unauthorized or erroneous, they must refund you immediately.

File a complaint with the regulator only if the bank fails to respond to your dispute within the required timeframe, or if they investigate and refuse to refund you despite clear evidence of error. Complaints about the bank's handling of a dispute (ignoring your request, missing the deadline, refusing to investigate) are valid regulatory complaints. Ask your bank for its dispute resolution process in writing, and keep proof that you filed the dispute on a specific date.

Frequently Asked Questions

Can I file a complaint if I do not have an account number?

You can file without an account number, but the bank will take longer to identify your account and investigate. Provide as much identifying information as you can: your full name, the date you opened the account, the last four digits of any card linked to the account, or the approximate balance. The regulator will work with the bank to locate your account, but it may add a week to the timeline.

What if the bank says the problem is my fault?

The regulator will investigate both sides. If the bank claims you authorized a charge or made an error, the regulator will ask the bank for proof—a signed authorization, a recording of a phone call, or documentation of the transaction. If the bank cannot provide proof that you authorized it, the regulator can order a refund. If they can, the complaint may close, but you can still pursue the matter in court if you believe the bank's proof is false.

Do I have to go to court if the complaint does not resolve?

No. If the regulator finds no violation or the bank refuses to refund you, you can choose to pursue the matter in small claims court, file a lawsuit, or let it go. Check your account agreement to see if it requires arbitration instead of court—many banks include arbitration clauses that require disputes to go to a private arbitrator rather than a judge.

Can I file a complaint on behalf of someone else?

You can file if you have power of attorney or are the account holder's legal guardian. Otherwise, the account holder must file their own complaint or give you written permission to file on their behalf. The regulator will ask for proof of your authority before investigating.

What if my bank is not in the United States?

If your bank is a U.S. branch of a foreign bank, it is still regulated by one of the four federal agencies and you can file a complaint. If your bank is entirely foreign and has no U.S. operations, the CFPB and federal regulators have no authority. You would need to file a complaint with the bank's home country regulator or pursue the matter through international channels, which is difficult and slow.
