The address on the health code will not be known to others, but the platform will keep personal privacy confidential. Only the platform will know your address, because that is the need of health code. If a person does not have a fixed address, your health code will not be generated, which is the need of setting. So don't worry that the address will be leaked, because registering the address in detail can fully prove the existence of a person.
Others can't find the address on the health code, because the address on the health code needs to enter the mobile phone number, micro-signal login and real-name authentication, and these others can't log in. They need a verification code when they need a mobile phone number, and a WeChat interface when they need a WeChat login. Therefore, the health code is absolutely safe and will not reveal personal privacy to others.
