- Select the corresponding Business Category and Business Entity. Enter the Business Authorization Code obtained from the CAAC Regional Administration Bureau. Enter the registration verification code, then click **[Next]** to enter the detailed registration page.
- Registration is a three-step process: "Basic Info - Detailed Info - Contact Info". When filling in Basic Information, please enter correctly according to your company's registration license information. Ensure accuracy, then click **[Next]** to complete this step.
- Note: When clicking "Next", the system validates the Legal Person information provided by the Regulated Entity. If a prompt appears stating "Your Legal Person real-name verification failed", it might be due to incorrect information entry or delays in the real-name database synchronization. First, verify key information like Legal Person Name and Unified Social Credit Code for accuracy. If confirmed correct, click **[Confirm]** to complete registration; the system will automatically re-validate later. If information is incorrect, please revise and resubmit. If verification still fails after registration, you can manually update it in the "Unit Information Management" module.
- Upon entering the Detailed Information page, regulated entities should fill in details according to the actual company situation. If registering a subsidiary company, check "Yes" in the "Is it a subsidiary?" field. Then, enter the parent company's name; the system will automatically suggest matching company names. Select one and the system will automatically populate the corresponding Parent Company Unified Social Credit Code. If the parent company is not in the CAAC system, its information must be entered manually. After completing all information, click **[Next]**.
- On the Contact Information page, confirm the setting of the company's System Administrator. Regulated Entities can choose one of two methods:
- 1.Set the Legal Representative as the Account Administrator
- 2.Set the Handling Personnel (经办人) as the Account Administrator** (requires Legal Representative authorization).
- If choosing the first option (Legal Representative), the system will directly register the Legal Representative as the administrator.
- If choosing the second option (Handling Personnel), register the specified Handling Personnel as the System Administrator based on the Legal Representative's authorization letter. Click the "Legal Representative Authorization Letter" template at the bottom of the page to download it.
- After downloading the template, have the authorized unit provide the letter with an official seal, then upload it to the "Legal Representative Authorization Letter" field to complete the authorization. After filling in all basic information, click the **[Submit]** button and wait for administrator approval. Once approved, the Regulated Entity registration is complete.
- Upon administrator approval, the Regulated Entity can log in using the credentials provided during registration.
