If you don't intend to apply for integrity, there are two situations:
1. Legal person member: (limited company and other enterprises with corresponding accounts)
WeChat official account can fill in the certificate for free;
2. Individual members: (self-employed, enterprises and some small factories without names)
When you apply for an Alibaba account, you should switch to a personal account, and then you can authenticate your real name through Alipay. It's also free.
However, it needs to be reminded that individual members can't open the integrity service yet!
