Insurance companies weigh multiple factors when calculating your car insurance rates, including your age, driving history, type of vehicle, and even your marital status. Not only do states have different laws and limits surrounding minimum liability coverage, but where you live within your state could also affect your driver risk profile. Insurance companies use your ZIP code to analyze your area’s weather patterns, rates of vehicle theft, likelihood of vandalism, average traffic congestion, and other factors that might lead you to file an insurance claim.
