How to verify an insurer before you buy
Buying insurance is buying a promise. The price is easy to compare and the promise is not, which is why most people compare the only thing that is visible. Five checks, all using public records and all doable in about twenty minutes, tell you considerably more about the promise than any comparison site will.
Why this matters more than the price comparison
The difference between two carriers quoting the same coverage is usually a few hundred dollars a year. The difference between a carrier that pays claims properly and one that does not is the entire value of the policy. The checks below are the ones that show up in the public record, and none of them require you to trust a review site.
One framing point before the list: the entity that matters is the licensed insurer, not the brand. A single marketing brand can front dozens of licensed subsidiaries with different ratings, different complaint records and different financial positions. Always run these checks against the legal entity named on the declarations page, and ask for that name in writing if it is not obvious.
The five checks
Licensing
What you are checking: Confirm the company is licensed or authorised to write the line of business you are buying, in your state.
How to do it: Your state department of insurance maintains a public licensee lookup, and the NAIC hosts a national directory of state regulators. Search the legal entity name from the policy, not the brand name — insurers frequently trade under a marketing name that is not the licensed entity.
Why it matters: An unlicensed carrier has no guaranty-fund backing if it fails, and no state market-conduct oversight. Selling insurance without a licence is also, in most states, a crime — which tells you what the policy is worth.
Red flag: The brand name does not appear in the state lookup, and the insurer will not give you the licensed entity name in writing.
Financial strength ratings
What you are checking: Check how the carrier is rated for its ability to pay claims, by more than one agency.
How to do it: The major rating agencies publish free summaries: AM Best (letter grades such as A+ or A−), S&P Global Ratings (AAA to CCC), Moody's (Aaa to C), and Fitch. Look up the rating of the legal entity that will issue your policy.
Why it matters: A home or life policy is a promise that may not come due for decades. The rating is the most widely used measure of whether the promise will be kept.
Red flag: A rating below the A range for a product you will hold for decades, or a rating that applies only to a parent company rather than the issuing subsidiary.
The complaint index
What you are checking: Compare the volume of consumer complaints a carrier receives against its market share.
How to do it: The NAIC publishes a Complaint Index for many carriers. A value of 1.00 means the company receives complaints at exactly the rate expected for its size. Above 1.00 means more than expected; below 1.00 means fewer. Many state departments publish their own complaint statistics as well.
Why it matters: This is the closest thing to objective evidence about how a carrier behaves when something goes wrong — and it is the number that claims experience actually produces.
Red flag: A complaint index well above 1.00, particularly if the complaints concentrate in claim handling rather than billing.
Market-conduct and enforcement history
What you are checking: Check whether the regulator has taken public action against the carrier.
How to do it: State insurance departments publish enforcement actions, fines and market-conduct examination reports. The NAIC also maintains a searchable regulatory actions database.
Why it matters: A pattern of enforcement action for claims-handling or rating violations is more informative than any single consumer review, because it reflects a regulator's findings rather than an individual's impression.
Red flag: Repeat findings on the same conduct across multiple states or examination cycles.
Whether they actually write in your state
What you are checking: Confirm the carrier is currently writing new business for your line and your state.
How to do it: Ask the agent or the carrier directly, and ask for it in writing. Carriers withdraw from states and lines quietly, and an aggregator site may still list a company that stopped accepting new applications.
Why it matters: A quote from a carrier that has stopped writing in your state wastes your time, and a policy from a carrier that is winding down a book raises questions about service and renewal.
Red flag: A quote you cannot get confirmed in writing, or a carrier that will only quote through one intermediary.
Reading a financial strength rating
Ratings are letter grades with different scales, and comparing a B++ from one agency against an A from another is meaningless without knowing what the scale means. The four agencies that matter for insurance:
| Agency | Scale | Focus |
|---|---|---|
| AM Best | A++ (Superior) down to D (Poor), plus S for rating suspended | Insurance-specific; the most widely used in the industry |
| S&P Global Ratings | AAA (Extremely strong) down to CCC | Broad financial strength; also rates the parent group |
| Moody's | Aaa (Exceptional) down to C | Broad credit and financial strength |
| Fitch | AAA down to CCC | Broad credit and financial strength |
Three practical rules for using them. First, check at least two agencies— a single rating can reflect a single methodology. Second, check the entity issuing your policy, not the group; a highly rated parent can own a thinly capitalised subsidiary. Third, look at the outlook as well as the rating. An A rating on negative outlook is a different proposition from an A rating on stable outlook.
There is no single cut-off that is right for everyone. The reasonable position for a policy you will hold for one year is different from the position for a permanent life policy or an annuity, where the promise may not come due for forty years and the consequences of carrier failure are far harder to unwind.
Using the complaint index properly
The NAIC Complaint Index is the most misunderstood number in this list. It isnot a count of complaints. It is a ratio: complaints received against complaints expected, given the carrier's share of the market. A value of 1.00 is exactly at the expected level.
- Below 1.00 — fewer complaints than the carrier's size would predict. Better than expected.
- Around 1.00 — at the expected level.
- Above 1.00 — more complaints than expected. The further above, the more this is worth investigating.
Two caveats. The index measures complaints filed with regulators, not complaints made to the company — so it captures the cases where a consumer escalated, which is a subset. And a carrier with a large book of business in a high-dispute line will look worse than a carrier writing a simpler product. Compare like with like where you can, and read the complaint categories rather than only the headline ratio: complaints concentrated in claim handling mean more to you than complaints about billing.
What public records will not tell you
Worth being explicit about the limits of this exercise, so you do not over-read it.
- It does not tell you how your own claim will go. Claims outcomes depend heavily on the adjuster, the specific facts and your own documentation.
- It does not reflect service quality. Nothing in the public record captures how long it takes to reach a human, or how a carrier handles a mid-term change.
- Consumer review sites are not evidence. They are unverified, unrepresentative and frequently gamed. Use the regulator's data instead, and treat reviews as a prompt to ask a question, never as the answer.
- Ratings lag. A rating reflects a financial position as of a date. Ask how recent the rating you are reading is.
A twenty-minute sequence
- Get the licensed entity name from the quote or the agent, in writing.
- Search that name in your state's licensee lookup and confirm the lines of business it may write.
- Look up two financial strength ratings for that entity, and note the outlook.
- Look up the NAIC Complaint Index and check which complaint categories dominate.
- Search for enforcement actions against the entity in your state and nationally.
- Confirm in writing that the carrier is currently writing new business for your line in your state.
If all five checks come back clean, the remaining variable is price and coverage structure — which is what our calculators andguides are for. If one comes back badly, the price is no longer the interesting question.
Frequently asked questions
Is a highly rated insurer guaranteed to pay my claim?
No. A rating measures the carrier's ability to pay, not its willingness to pay on your particular facts. Coverage decisions turn on the policy wording and the evidence. A strong rating plus a clean complaint record plus your own documentation is the best combination available.
What is a good NAIC complaint index?
1.00 is the expected level for a carrier's size. Below 1.00 is better than expected. There is no official threshold, but a sustained index well above 1.00 is a reason to look at the complaint categories before you sign.
Which rating agency matters most for insurance?
AM Best is the most insurance-specific and the most widely cited within the industry. Using it alongside one broad agency — S&P, Moody's or Fitch — gives you two independent methodologies rather than one.
How do I find the licensed entity behind a brand name?
Ask the agent or carrier for the full legal name of the issuing insurer, in writing. It will appear on the declarations page of any policy. If a seller will not tell you which legal entity will issue the policy, that is itself informative.
Does my state guarantee fund protect me if an insurer fails?
Most states operate a guaranty association that pays claims, up to statutory caps, when a licensed insurer becomes insolvent. The caps vary by state and by line of business, and coverage is generally more limited for annuities and high-value policies. Guaranty protection is a backstop, not a substitute for checking the rating.
Should I trust online reviews of insurance companies?
Not as evidence. Review platforms are unverified, self-selecting and frequently manipulated in both directions. Use them to generate questions, then answer those questions with the regulator's data and the carrier's own documents.
