Alipay is generally certified by real-name registration system, and it is bound to the mobile phone number, so clicking on the health code inside is the health code of the person whose real name is certified. If you don't see the health code, in one case, you can look at it and see if it is wrong. You can search on the Alipay search interface, allowing you to fill in the corresponding information and generate your own personal health code. If you don't find the health code, it means that you didn't get the real-name authentication, so you can't see it.
Click search, enter the health card, and it will come out.
It may not be on the page. You can search the health code.
