Subject to the provisions of this subchapter, two or more agents holding active licenses of the same type may jointly advertise or otherwise jointly present their agency names to the public. In such instances, any solicitation put forth by an individual agent or any policy, binder, certificate of insurance, endorsement, invoice, or billing must clearly and exactly identify the specific agency making the solicitation or servicing the insurance account in question. No agent shall make any representation, whether written or oral, that such agent is an authorized representative of any insurer unless the agent has been properly appointed to act as an agent for such insurer.
