It cannot be directly used in other areas, but the relevant information has been shared with other cities through the national government service platform "Epidemic Prevention and Health Information Code". At present, Hebei, Shanghai, Hangzhou and other places can certify the status of Beijing health code.
"National Health Code" can realize mutual recognition of health codes in different cities in three ways. First, through the cross-regional epidemic prevention and health information data sharing, the cross-regional mutual recognition function is added to the local health code; Second, local health codes are transformed from "national health codes" to realize mutual recognition of cross-regional health codes; Third, in areas where local health codes have not been established, the "National Health Code" can be directly adopted. Knowing your experience, I found that when applying for "National Health Code", you only need to authorize personal identity information and fill in the health declaration of the day, and the "green" information of Beijing health code you applied for before will be automatically imported and displayed as "low risk". Later, when applying for health codes in Hebei, Shanghai, Hangzhou and other places, Beijing's certified "green code" information will be automatically accessed.
