Method and source
Source: the Illinois insurance regulator company list, read 2026-10-18. IDOI 2025 Market Share Report: Property and Casualty (published March 2026, 2025 annual-statement data). Lists every company with Illinois business written on the P&C statement: licensed companies, surplus lines insurers and risk retention groups together, with no status/type flag, so type is '' for all rows and the list is NOT a certificate-of-authority roster (a licensed company with zero IL premium and zero losses is omitted; non-admitted writers are included). 'lines' = P&C statement lines of business the company reported IL premium or losses under (48 of 54 lines have entries), a proxy for lines of authority. No 'since' date in the source. No Illinois surplus lines eligibility list exists (IL has no white list). 26 companies had a name or domicile cell missing in at least one PDF row; filled from the same NAIC code's other rows. "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.
