Step 1: Log in to official website, the State Administration of Electronic Taxation, select the real-name registration system on the page, and enter the ID number and password to complete the login.
Step 2: After logging in, the tax status selection will pop up, and corporate tax can be seen on the right side of the page.
The third step is to select the enterprise that needs to log in, and then the enterprise enters, and the "taxpayer information" can be seen on the home page.
Step 4: Click to enter the taxpayer information page to view the relevant information of the enterprise.
Step 5: Slide the mouse and drop down the page to view the corporate ID number.
When registering for industry and commerce, it is necessary to register the ID number of the legal representative of the enterprise. But you can't find it on the regular network. You can log in to official website and the National Enterprise Credit Information Publicity System, enter the name and location of the enterprise, and you can find the relevant information of the enterprise, such as social credit code, person in charge, date of establishment, historical name and so on, but there is no legal agent's ID number.
The business license and enterprise ID number cannot be made public, and neither can the industry and commerce, because with the business license and enterprise ID number, many things can be done, such as reporting to the national tax. Therefore, it is the responsibility of industrial and commercial institutions to ensure the security of legal person identity information and not provide a way to obtain legal person identity numbers.
