A broker license is issued state by state, and no brokerage holds one everywhere. That is ordinary in this market and it shapes how a case is actually handled. A firm licensed in the seller state works the case directly. Outside that footprint it partners with a licensed broker who also represents the seller.
The question for a policyowner is not whether a firm is licensed in all fifty states, because almost none are. It is which entity will hold the license on this transaction, and whether that entity represents the seller or the buyer. Both answers should be given in writing before anything is signed.
