The National Association of Insurance Commissioners (NAIC) is a U.S. standard-setting and regulatory support organization created and operated by the chief insurance regulators of all 50 states, the District of Columbia and five U.S. territories.

The NAIC's primary mission is to support state insurance regulation and provide a forum for coordination and collaboration among state insurance regulators. The organization is responsible for developing and adopting uniform insurance laws and regulations, providing education for regulators and the industry, and conducting research related to the insurance industry.

One of the key ways the NAIC is used in the insurance industry is through its development of model laws and regulations. These models serve as a basis for state insurance departments to create their own laws and regulations, ensuring consistency and uniformity across the country. Additionally, the NAIC provides education and training programs to insurance regulators and industry professionals to ensure they are up-to-date on the latest regulations and best practices.

The NAIC also administers a number of important initiatives and programs, including the Interstate Insurance Product Regulation Compact, which allows insurers to more efficiently file and obtain approval for their insurance products across multiple states.

Overall, the NAIC plays a critical role in regulating and supporting the insurance industry in the United States, providing consistency, standardization, and support to state-level regulators and industry professionals alike.
