Every property and casualty insurer admitted in Rhode Island 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.
1,052 property and casualty insurers are on Rhode Island's regulator lists: 840 licensed (admitted) companies and 212 eligible surplus lines insurers for risks the standard market turns down.
By Sam Alishahi, independent insurance broker · All states
Companies on the U.S. Treasury's Circular 570 (acceptable sureties on federal bonds) that list a Rhode Island license, with each one's federal underwriting limit.
Source: the Rhode Island insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = RI DBR 'Property & Casualty Insurers' roster (Report Date October 2, 2026, Company Count 840): a category list of licensed P&C insurers with NAIC codes; no per-line authority, no license dates, no domicile (type is the roster category; domicile/type overridden from the RI_Domestics companion list for the 29 RI domestics). Life/health insurers are on separate DBR lists and are not included. Surplus lines = 'Registered US Domiciled Surplus Lines Insurer' list (Report Date October 2, 2026, Company Count 212); RI defers non-US insurers to the NAIC IID Quarterly Listing of Alien Insurers, so alien=true only for the few legacy no-NAIC UK entries still on the list. No eligibility dates given. address/phone kept as extra fields. surplus: the PDF carries 48 stale rows after the alphabetical list ends (older render left in the file; dropped).

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.

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.
