Can the Health and Health Commission find the mobile phone number bound by the health code?

The Health and Health Commission can find the mobile phone number bound by the health code. The binding of health code requires personal identification information and mobile phone number to register and receive health code. Health codes are based on actual data, which can be generated by citizens or people who have returned to work through their own online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city.
