Insurance companies licensed in New Hampshire

Every property and casualty insurer admitted in New Hampshire and every eligible surplus lines insurer, with NAIC numbers, the lines each is licensed for, who writes the most of each line, and the market of last resort when nobody else will.

New Hampshire's regulator doesn't publish a company list that can be read by machine (or it's behind a CAPTCHA or terms that bar automated use), so this page shows what public sources do say: 194 sureties licensed in New Hampshire per the U.S. Treasury, 46 insurers domiciled here, the state's markets of last resort, and each company's standing in the states that do publish lists.

Method and source

New Hampshire publishes its company list through a lookup that can't be read by a program, so the table above is built from the other states' lists, NAIC numbers, the U.S. Treasury's surety list and market share reports. A company missing here may still be licensed in New Hampshire; check the regulator's lookup. Lines are the regulator's licensed lines grouped into common names; a license to write a line doesn't mean a company sells it to every kind of customer. "Admitted" means licensed by the state and backed by its guaranty fund; "surplus lines" means eligible to take risks the admitted market declines, without rate or form approval and without guaranty fund protection.

Need insurance in New Hampshire?

Someone will insure it. I find who.

Send what you need covered and what happened before. I match it to the companies that take it, down to the last-resort plan if it comes to that. I'm licensed in 48 states and Washington, DC and your request stays with my agency, not passed to another agent. In Florida and Washington, where my licenses are still being issued, a partner agency in your state helps in the meantime.
