21st Century publishes no SR-22 page we could verify.

Does 21st Century file SR-22s?

Their own site does not say. That last sentence settles it for most readers. 21st Century is a Farmers company still writing new business, but only in California. Anywhere else, there is nothing to ask about.

Why doesn't this page just answer the question?

Because answering it would mean inventing a fact about a named company. This page previously did exactly that, with specifics that had no source. Those have been removed, and what replaced them is either a quotation or nothing.

Where can I get a definitive answer?

From 21st Century directly if you are already a customer, or from a licensed agent who knows which carriers are writing high-risk filings in your state this week. Underwriting appetite changes; published pages do not.

Which carriers do say they file?

Several state it plainly on their own sites. Where they do, we quote them and link to the page so you can check it yourself.

No car to insure? How a non-owner SR-22 works. In Florida or Virginia after a DUI, the form is usually the FR-44 instead: what changes.
