United States · Insurance market profile

The Massachusetts insurance market

Massachusetts has its own insurance supervisory authority, the Massachusetts Division of Insurance. This profile brings together its regulatory contacts, NAIC research and the companies recorded as domiciled here in our directory.

Boston is the capital. A US state since 1788, Massachusetts 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 Massachusetts domicile records, General (Non-life) is the largest recorded class, with 50 entities. This describes the composition of our listings, not premium market share.

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

Regulator details, nicknames and mottos were checked against the regulators’ own sites and public references on 23 Sept 2026. Flags are public-domain artwork. This is reference information, not register data.
