Method and source

Source: the North Dakota insurance regulator company list, read 2026-10-18. ND Insurance Department 2024 Statistical Report, 'State Page Data for Licensed [Non-]Domiciled Health/Life/Property/Title Insurance Companies as of December 31, 2024'. Every licensed company with an NAIC code; type is the report section (Health, Life, Property & Casualty = the 'Property' auto + fire/multi-peril sections, Title; joined with '; ' when a company appears in more than one). domicile is 'ND' for the domiciled sections and blank (unknown) otherwise. The report carries no certificate-of-authority lines, only premiums by line group, so lines is always []. The 9 ND county mutuals (no NAIC code) are appended with type 'County Mutual' and since = year admitted to ND. North Dakota publishes no surplus lines eligibility list. Section counts: Health domiciled 2 (report 2); Health non-domiciled 65 (report 65); Life domiciled 3 (report 3); Life non-domiciled 406 (report 406); Property domiciled 13 (report 13); Property non-domiciled 826 (report 826); Property domiciled 13 (report 13); Property non-domiciled 826 (report 826); Title non-domiciled 18 (report 18); County Mutual 9 (report 9). "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.
