A policy number is a unique identifier assigned to an insurance policy. It helps both the policyholder and the insurance company keep track of the specific terms, coverage, and details of the agreement. This number is essential for filing claims, making payments, and accessing customer service. When you purchase insurance, whether it's for health, auto, or home, you will receive a policy number. This number is usually found on your insurance card or policy documents. Always keep it handy, as you may need it when contacting your insurer or during emergencies related to your coverage.
