What is the difference between an insurance broker and an insurance agent?

An insurance agent represents the insurance companies for which the agent has been appointed; an insurance broker represents the customer. Because brokers do not represent insurers, they cannot bind coverage, and the transaction must be completed by an agent or the company itself. New York's Department of Financial Services describes the same split: agents act for appointed New York authorized companies, while brokers act for the insured and can place business with any authorized company that will accept it.
