Department of Insurance
The state agency that licenses insurers, reviews rates, and enforces insurance law. Every state has one, though several run it under another name.
A Department of Insurance (DOI) is the state agency that regulates insurance within a state. It licenses insurers and producers, reviews policy forms and rates, investigates consumer complaints, and conducts market conduct examinations. The head is usually called the Insurance Commissioner or Superintendent, and the agency is not always a department of insurance by name: New York regulates its insurers through the Department of Financial Services.
For insurance AI, the DOI is the actual enforcement authority. The NAIC writes model guidance, but a state’s DOI decides whether to adopt it, how to interpret it, and how to examine carriers for compliance. That means carriers face 50-plus regulatory regimes, even when the NAIC baseline is widely adopted.
State DOIs also respond to federal initiatives. When Executive Order 14365 directed federal agencies to challenge state AI laws, the commissioners answered through the NAIC that the order reached routine analytical tools and the risks regulators handle in pricing and claims, and asked the administration to leave insurance AI with the states.
