What do you mean, the license plate number has no underwriting information?

It is possible to insure first and then go public.

The car should be a new car when it is insured, so there is no license plate number on the policy. If it is listed, you should contact the insurance company to correct it in time. When a new car purchased in Shenzhen 4S store (car dealership) needs to be corrected to a non-Guangdong B license, it needs to be handled in Shenzhen store. If in doubt, you can contact auto insurance customer service for consultation.
