For example, in Zhejiang, after the user fills in the health information, no matter whether he has had contact with the confirmed or suspected patients in COVID-19 within 14 days, a color code will be generated after the approval. The color code will vary according to the user's own filling situation, and you will get a red code, a yellow code or a green code.
Inter-provincial mutual recognition of health codes:
1. In order to promote the mutual recognition of "health code" in different places, the national comprehensive government service platform provides three ways to realize cross-provincial mutual recognition and sharing.
2. The first way is to add the cross-regional mutual recognition function to the local "health code" through the cross-regional epidemic prevention and health information data sharing without changing the existing local "health code".
3. The second way is that the local "health code" is connected with the national comprehensive government service platform "epidemic prevention information code", and the national comprehensive government service platform "epidemic prevention information code" is used as the intermediary to realize the mutual recognition of cross-regional "health code".
4. The third is that in areas where there is no local "health code", the "epidemic prevention information code" of the national comprehensive government service platform can be directly adopted, and at the same time, combined with local epidemic prevention and health-related information, cross-regional mutual recognition can be realized.
