• A registered agent is an individual or company authorized to represent an insured in purchasing, maintaining and maintaining insurance coverage from a designated insurer. Most insurance companies will not disclose any information or discuss an insured’s account with any agent other than a registered agent. An insured wishing to change insurance agent must submit a revised agent registration letter to the insurer authorizing the insurer to disclose the insured’s information and discuss the insured’s coverage with the new agent.
