Will the health certificate number change when the health certificate expires?

When the health certificate expires, the health certificate number will not change. To apply for a health certificate, I need to go to a designated hospital registered in real-name registration system with my ID card. The number of the health certificate is the ID number, and everyone's ID number is different. I use it for myself. The health certificate is valid for one year. If it expires, it will be invalid and needs to be re-applied. Therefore, the number of health certificates applied by the same person each year remains unchanged.
