What is the term for an insurance company chartered in the same state as its home office?

The term that describes an insurance company chartered in the same state as its home office is "domestic insurer." This designation indicates that the insurer is licensed and operates under the regulations and laws of the state in which it was established.

A domestic insurer usually has a significant understanding of the local market and is subject to the specific state’s insurance laws and regulatory framework. This local knowledge helps the insurer tailor its products and services to meet the needs of policyholders within that specific geographic area. The concept of a domestic insurer is central to understanding the broader categorization of insurance companies, which can also include foreign and alien insurers, depending on where they are chartered relative to the state in question.
