Wenzhou epidemic prevention code automatically associates the health code information of users and related personnel. When in use, the epidemic prevention code information of relevant personnel can be displayed through the "Switch Applicant" button. For children without a second-generation ID card, any parent must first apply for Zhejiang health code through the "family agent" on the "Zhejiang health code", and then apply for re-association through the "Wenzhou epidemic prevention code". The time interval is 1-2 hours. Pay attention to the consistency of mobile phone numbers, otherwise the association cannot be obtained from Zhejiang health code. That's enough.
