A more thorough explanation:

An insurance certificate is a document that proves you have insurance or are a member of an insurance or pension plan. It can also be a document that shows a shipment of goods is covered by a marine insurance policy.

1. If you have car insurance, your insurance company will give you an insurance certificate. This document proves that you have insurance and shows the dates that your policy is valid.

2. A company that ships goods overseas may need to get a marine insurance policy to protect their goods during transport. The insurance company will give them an insurance certificate to show that their shipment is covered.

These examples show how an insurance certificate is used to prove that you have insurance or that a shipment is covered by insurance. It is an important document to have in case you need to show proof of insurance or coverage.
