No. Filing certificates is a service a carrier chooses to offer, and plenty of standard companies do not. A policy from a carrier that does not make filings cannot satisfy the requirement even though it is real insurance.

This is one of the more expensive surprises in the process, because it usually surfaces after the driver has already paid a premium. The sequence goes like this: a driver buys a cheap policy online, calls to ask for the filing, and learns the carrier does not do them. The policy is valid, the money is spent, and the proof period has not started. The fix is to ask the question before binding, not after. Carriers that specialize in nonstandard auto almost universally handle filings, because that is the market they serve. Independent brokers who work that segment know which of their carriers do, which is a large part of the value of using one rather than shopping carrier websites one at a time.
