After opening the national government service platform, select a modification in the upper right corner of the health code, and then re-fill in your current area. Submit after repeated confirmation.
As the general hub of national government service, the national government service platform takes the three functions of public entrance, public passage and public support as the core, and provides "seven unifications" support services such as unified government service portal, unified government service item management, unified identity authentication, unified electronic seal, unified electronic license and unified data sharing for government service platforms in all regions and departments of the country to achieve support. There are also many restrictions on modifying areas, because they are all located according to your location. You can contact the official customer service at 12345.
