If it is found immediately after the insurance is completed, you can ask the insurance company to change a new policy; If the insurance policy has been in effect for a period of time, it is necessary to go through the formalities of correcting the mistakes in the insurance policy. The method is: write an application for changing the license plate number (insurance policy number, wrong insurance policy and signature or seal), bring your insurance policy and driving license, and find the business management department of the insurance company. They will send you an approval form to correct the mistakes in the insurance policy, which will indicate the correction of the mistakes. If the wrong item affects the amount of premium, part of the premium will be increased or refunded. In this way, you have completed the policy correction. Please remember that this approval form should be used together with the insurance policy when making a claim.
