Shanghai Municipal Office of Prevention and Control has come to remind you when short messages will work.

If you receive a text message, it will take at least seven days to go to work.

Don't panic when Green Code receives the short message from Shanghai. Confirm the content of the message. If it is just a reminder, don't worry. If there is a follow-up, he will tell you what to do. After receiving the prompt, you can make your own nucleic acid test report and be responsible for yourself and your family. Health codes are based on actual 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.
