Q: I have a merchant ID and an Official Account. How can I know whether their entities are the same?

A: To check whether the corporate entities are the same, log in to the WeChat Official Accounts Platform and choose Account Info to view Entity Info, and go to the homepage of WeChat Pay Merchant Platform to view the entity.

Q: We are in the group-subsidiary relationship. We want to issue member cards created by the group's Official Account to users who pay money to the subsidiary's merchant ID. However, when we use the subsidiary's AppID to configure a rule for the subsidiary's merchant ID[TH1], an error 72002 is reported when we are setting the group's card_id. What can we do?

A: In this case, you can log in to WeChat Open Platform (https://open.weixin.qq.com/) to link Official Accounts of all subsidiaries to the group's third-party platform account. After that, cards can be issued from both the group's ID and subsidiaries' IDs, and members can be identified by all of them (in other words, the UnionID mechanism is applied).
