How to file a complaint against an insurance company
Claim denied, delayed, underpaid, or policy canceled — health, auto, home, or life. Here is exactly which regulator has jurisdiction, where to file, and what to say.
The right regulator(s), in order
state
Your State Department of Insurance
Insurance is regulated at the STATE level. Your state's Department of Insurance is the primary regulator and can order the insurer to respond and re-review. This is the single highest-leverage route.
State/local office — opens the official directory; pick your state, then your office. (Verify the link is current.)
Your full name, address, phone and email
The exact legal name and address of the business/agency you are complaining about
Your policy number and claim number
The dates of what happened (in order)
The denial/EOB letter and the policy language you believe was misapplied
The dollar amount in dispute or the harm/loss
The specific outcome you are asking for
federal
NAIC — National Association of Insurance Commissioners
The NAIC routes your complaint to the correct state regulator and tracks the company's complaint history. Use it if you are unsure which state has jurisdiction.
The exact legal name and address of the business/agency you are complaining about
The dates of what happened (in order)
Copies of contracts, statements, photos, emails, and letters (keep originals)
The specific outcome you are asking for
Any prior attempts you made to resolve it directly
If this is a health-insurance claim denial, draft a formal appeal first (an internal/external appeal often wins before a regulator gets involved). Open →

Does filing a complaint get me my money back? A regulator complaint pressures the company to fix it and creates an enforcement record, but it does not award you damages. For a specific dollar amount, small-claims court is usually faster. For injury or large losses, talk to an attorney.
Will they know I complained? Most consumer complaints are shared with the company so it can respond. Some (e.g., OSHA, wage) let you stay confidential — we note that on each agency.
How long does it take? Many agencies require the company to respond within 15–60 days. Keep your case number and the dates.
Complaint-routing & drafting information — not legal advice or representation. This is a self-help tool that points you to the regulator with jurisdiction and drafts a complaint for you to review and file. It is not a law firm, and using it does not create an attorney–client relationship. Which agency applies can depend on facts we don't see (the company's charter, your state, the exact conduct). Government portal links — especially state-level ones — can change; we show the official directory as a fallback and the date each was checked (2026-06-25). Some situations are legal claims for money or injury, not regulator complaints — we flag those and you should consult a licensed attorney in your state.
