The National Insurance Crime Bureau explained
What the NICB is, who funds it, what its agents and data do, what it does not do, and how drivers can use its free VINCheck and fraud tip line.
The National Insurance Crime Bureau (NICB) is a not-for-profit organization, supported by insurance companies, that investigates insurance fraud and vehicle theft across many insurers at once and works with police and prosecutors to bring cases. It is not a government agency or a regulator, and it does not handle complaints about your insurer. For drivers, its most useful services are a free stolen-and-salvage VIN lookup and a tip line for reporting suspected fraud.
Where the NICB came from
According to the NICB, it was formed in 1992 by merging two not-for-profit groups: the National Automobile Theft Bureau, which dated to the early 20th century and ran vehicle theft investigations and databases for insurers, and the Insurance Crime Prevention Institute, which had investigated insurance fraud for about 20 years. That lineage is why the NICB still describes itself as having a 110-year heritage. Its headquarters is in Oak Brook, Illinois.
Who funds and runs it
The NICB says its membership includes more than 1,200 property-casualty insurers, vehicle rental companies, auto auctions, vehicle finance companies, self-insured organizations and strategic partners, and that it has nearly 400 employees (as stated on its site in October 2026). Members fund it and get access to its investigative help, data and training. That structure matters when you read NICB material: it is an industry organization whose mission is fighting crime against insurers and their customers.
What the NICB does
- Investigations. NICB agents focus on what the organization calls "multi-claim, multi-carrier" cases: rings that file claims with several insurers, which no single company's special investigations unit can see on its own. Member SIUs refer suspicious claims electronically, and agents in eight regional field offices work with law enforcement to support criminal and civil cases. NICB agents also take part in insurance crime task forces.
- Vehicle theft and recovery. Its Investigative Assistance group answers calls from police and members and, the NICB says, produces thousands of vehicle recoveries and investigative leads a year.
- Intelligence and analytics. Analysts look for patterns in industry data, such as the same people, clinics or vehicles appearing in many claims.
- Training. It runs courses and academies for police officers, insurance investigators and analysts.
- Disaster response. After hurricanes and floods it warns consumers about contractor fraud and flood-damaged cars.
- Public and government affairs. It publishes consumer warnings on topics such as staged accidents, ghost brokers and predatory towing, and it advocates for anti-fraud laws.
What it is not
- Not law enforcement. NICB agents investigate and share evidence, but arrests and charges come from police and prosecutors.
- Not a regulator. It doesn't license insurers or approve rates. That is your state insurance department's job (what your state insurance department does).
- Not a complaint line. The NICB says it "does not address concerns about an insurance company's service or rates" and sends those to the insurer. If your claim was underpaid or denied, see how to file a complaint against a car insurance company.
Here is how it fits with the other players:
| Organization | Who runs it | What it does for you |
|---|---|---|
| Your insurer's SIU | The insurer | Investigates suspicious claims on its own policies |
| NICB | Not-for-profit, funded by members | Multi-insurer fraud and theft investigations; VINCheck; tip line |
| State fraud bureau | State government | Investigates and refers fraud for prosecution (state insurance fraud bureaus: who investigates and how to reach them) |
| State insurance department | State government | Licensing, rates, consumer complaints |
| Police and prosecutors | Government | Arrests and criminal charges |
Tools drivers can use
VINCheck
The NICB's free VINCheck tool tells you whether a vehicle identification number has been reported stolen and not recovered, or reported as salvage, by participating member insurers. Its terms say the database covers vehicles reported stolen within the past five years that remain unrecovered or were declared salvage, and that searches are limited to five per IP address per day.
It is a quick screen, not a history report. The NICB itself warns that many stolen and salvage vehicles are not in the database, that "total loss" and "salvage" are not the same thing, and that records can be wrong or out of date. If a VIN is flagged as stolen, it asks you to confirm with the NICB or police before acting. Pair it with a federal title-history report, as explained in Run a VIN check before you buy a used car.
Reporting fraud
You can report suspected insurance fraud to the NICB by calling 800-TEL-NICB (800-835-6422), Monday through Friday from 7 a.m. to 7 p.m. Central time, or through the online form on its Report Fraud page. Useful details include names, addresses, vehicles and plates, dates, claim numbers and how you learned of the scheme. If you were the victim of a crime, the NICB tells you to contact local police as well. The full set of options is in how to report insurance fraud.
How to read NICB numbers
The NICB is a frequent source for news stories about fraud and theft. Two things help in reading its figures:
- Check the scope. The NICB's report-fraud page cites an estimate of about $308.6 billion a year in insurance fraud losses in the U.S., and an estimated $900 increase in annual premiums, both from the Coalition Against Insurance Fraud. Those figures cover all lines of insurance, including health, life and workers' compensation, not only auto.
- Check the source data. Many NICB reports count claims filed with its member insurers, so they describe trends in insurance claims rather than every crime reported to police.
Key takeaways
- The NICB is an insurer-funded not-for-profit that investigates fraud and vehicle theft across many insurers and supports police and prosecutors.
- It was formed in 1992 from the National Automobile Theft Bureau and the Insurance Crime Prevention Institute.
- It is not a regulator or complaint line; take service and rate problems to your insurer and state insurance department.
- VINCheck is a free stolen-and-salvage screen limited to five searches a day; use it alongside a full title history.
- Report suspected fraud at 800-TEL-NICB (800-835-6422) or through its online form.
