Moving ZIP codes and addresses can be similar to moving states, but on a much smaller scale. Car insurance companies look at it the same way. They’ll compare the crime rates, traffic incidents, and statistical features of one ZIP code to another to come up with a new insurance premium that fits the level of risk in that area. The ZIP code could be one where there are a large number of insurance claims made for injuries, stolen cars, property theft, or vandalism. And, all those could affect your car insurance premium.
