An insurance broker will need the same information as any insurance professional, including info about the insurance products you need and your personal details. So if you’re looking for the best car insurance company, for example, the broker will ask about your car, annual mileage and driving history, along with things like where you park the vehicle and which coverage types are important to you. Working with a broker gives you the opportunity to ask questions and talk about any concerns you have, so you might want to take advantage of that as they’re gathering information from you.
