Who writes warranty in Oregon
Top insurer groups from the NAIC market share report; the state's list carries no lines of authority.
Zurich Insurance Group wrote the most warranty in Oregon in 2025, $3.6M and 42.8% of the state's premium; the top five groups hold 88%. Oregon's company list doesn't say which lines each company is licensed for, so the ranking below is the NAIC's top 10 groups; every licensed company is on the Oregon page.

Method and source
Source: the Oregon insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = companies in Oregon DFR's 2025 market-share PDFs (property-casualty-totals.pdf plus the per-line PDFs linked from the financial-statements page). Some per-line PDFs (the life ones) still show 2024 data. Only insurers authorized in Oregon appear and companies with zero Oregon premium are excluded, so a licensed company that wrote nothing is missing. Names are NAIC short names (Ins Co, Amer, Natl). type comes from which reports list the company (Property & Casualty first, then Accident & Health, Life, Title); lines are the 'Line of Business' headers of the per-line PDFs the company appears in, spelled as published. since is not published. Surplus lines = SLAOR's eligible insurer listing (current names only; 78 former-name history rows and the 'MISCELLANEOUS - requires prior approval' placeholder dropped). It has no NAIC codes, domicile or eligibility dates, and none of its insurers appear in the DFR market-share PDFs, so naic is empty and must be filled by name in the merge. alien is a heuristic: foreign corporate suffix (Ltd/SE/AG/S.A./DAC/Club...), a US process-agent law firm as the address, or no US city/state/zip on file. "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.
