Telecom users encounter yellow code.

The yellow code has nothing to do with the operator, but with your recent action trajectory. You can consult the telecom customer service.

There are three health codes:

Green code can enter directly, red code isolation 14 days, yellow code isolation within 7 days. The health coding system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places. Through the health code, many health applications such as one-code medical treatment, appointment registration, one-click first aid, psychological assistance, health certificate, health file and so on have been realized.

Health codes are based on real data and can be generated by citizens or people who have returned to work through 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. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.

The application scope of health code covers community management, resumption of business, transportation, starting school, drug purchase registration, supermarkets and shopping malls, which can help communities, enterprises and schools to do key work such as epidemic prevention management and epidemic control.
