I have already registered a Tencent E-Sign Service account. Do I need to register again on WeCom?
No, you can directly bind the authenticated enterprise account on WeCom by following these steps.
1. Select an account.
WeCom Mini Program: On the upload business license page, click Link WeChat Account.
WeCom Workbench: On the enterprise authentication method selection page, select Bind Authenticated Enterprise Account.

2. Select the electronic sign account you want to bind.

3. Super Administrator Authorization.
If you are the super administrator of the enterprise you want to bind: follow the page guidance, check <Enterprise WeChat Electronic Signing Access Agreement> and complete facial recognition to bind the account.

If you are not the super administrator of the enterprise you want to bind: contact the super administrator for authorization to complete the account binding.

When I have two WeChat accounts on my phone, which account should I authorize to the Tencent E-Sign Service application? What should I do if I have authorized the wrong account?
Some customers may have two WeChat accounts on their phone. When you open the Tencent E-Sign Service application for the first time, the system will prompt you to confirm which WeChat account you want to authorize to Tencent E-Sign Service. Make sure to select the WeChat account authorized to WeCom.

For customers who authorized incorrectly, follow these steps:
1.1 Exit the WeCom app, and also log out of the WeChat account that is not bound to WeCom. Then, in the WeChat app, go to Settings > Personal Information and Permissions > Authorization Management, and revoke the permissions already authorized to the WeCom application.
1.2 Go to WeCom, clear cache (Settings > General > Storage > Clear Cache), then exit the WeCom application.
1.3 Reopen the WeCom app and reauthorize the application.

Why does the system prompt that the enterprise name, legal representative name, or address is incorrect after uploading the business license?
Because your business license has had an update record within the last 7 working days, please re-upload the business license after 7 working days. If you have any objections, please contact Tencent E-Sign Service customer service.
