The insurer groups that write the most credit in Idaho

Top 10 insurer groups by direct premium written in 2025, from the NAIC's Market Share Reports for Property/Casualty Groups and Companies by State.

Method and source

Source: the Idaho insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = every company licensed in Idaho per the DOI 2024 Annual Report roster (pp. 42-76), all four sections kept with 'type' = Health / Life & Annuity / Property & Casualty / Title so the merge can filter; 'since' = IDAHO LICENSE DATE; 'lines' = LINE(S) OF BUSINESS split on ';' (duplicates removed). Counts by type: {'Health': 23, 'Life & Annuity': 419, 'Property & Casualty': 870, 'Title': 18}. Domicile 'Canada' mapped to CN; one row (80659) has no domicile printed. Companies withdrawn in 2024 (report p.35) are not in the roster. Surplus = SLA of Idaho eligible list: no domicile or eligibility date on the page; alien insurers carry an AA- import code in 'import_code' and naic '' (two AA- rows are labelled Foreign on the page but flagged alien here); DECLO ASSURANCE CORPORATION shows code 'ID 4862' (not a NAIC code). "Premium" is direct premium written in the state for the year shown; "share" is that company's part of the state total for the line. A company can be licensed for a line and write none of it, and a surplus lines insurer can write a line without a state license for it.

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.
