Maine Bureau of Insurance
United States · Insurance market profile
Maine has its own insurance supervisory authority, the Maine Bureau of Insurance. This profile brings together its regulatory contacts, NAIC research and the companies recorded as domiciled here in our directory.
Augusta is the capital. A US state since 1820, Maine is part of a state-based insurance system: a company's home jurisdiction and the markets where it is authorised to operate are different facts.
Within this directory's Maine domicile records, Health / Medical is the largest recorded class, with 10 entities. This describes the composition of our listings, not premium market share.
Partial directory coverage. These counts are not the total number of insurers licensed in Maine.

No insurers match that filter.
Popularity is an estimate of how often people search Google for each insurer, from 0 to 100; the bars show how confident the estimate is. Not a rating of the insurer. How the index works
An insurer’s domicile is the state or territory where it is incorporated, and that jurisdiction’s regulator is its primary supervisor. Domicile here comes from the register rows: the Texas Department of Insurance register records each company’s state of domicile, and a captive on the Vermont captive register is domiciled in Vermont. A state’s list is therefore the insurers in this directory that call it home, not its regulator’s own register of every insurer it licenses.
To see where a company is licensed, use the NAIC’s national search, which covers every state: NAIC Consumer Insurance Search
