How many days is the health code valid?

The health code is valid for three days. In fact, the "health code" is based on real data. Citizens or people who have returned to work can declare online by themselves, and generate personal QR codes after background review. It is worth noting that the health code is divided into "green code", "yellow code" and "red code" management, and the "green code" personnel take their temperature at the bayonet or temperature measuring point, and are allowed to pass without fever symptoms; "Code Yellow" and "red team" personnel cannot pass. The health code will be transcoded according to personal health status and punching, and the "green code" is valid for three days. During the validity period, citizens must complete health registration at least once before they can get an automatic extension, otherwise they will be turned into "yellow code".

Legal basis: personal health information code

The national standard series of personal health information codes include Personal Health Information Code Reference Model (GB/T 3896 1-2020), Personal Health Information Code Data Format (GB/T 38962-2020) and Personal Health Information Code Application Interface (GB/T 38963-2020)3. Among them, the reference model of personal health information code stipulates the composition and presentation form of health code, and puts forward the reference model of health code application system and the technical mechanism of cross-regional mutual recognition. The data format of personal health information code stipulates the data structure, data element attributes and data management requirements of personal health information needed for epidemic prevention and control. "Personal health information code application interface" specifies the interface of personal health information service. Various applications can connect different personal health information services through a unified interface, which provides technical support for breaking through the territorial management restrictions of personal health certificates and facilitates the cross-regional flow of travelers all over the country.

After the implementation of this series of national standards, the coding system, display mode and data content of personal health information codes can be unified, and the protection of personal information and the enjoyment and utilization of information can be considered as a whole, which is suitable for guiding the design, development and system integration of health code-related information systems.
