The registered address must be a genuine and valid commercial address (in some cities, residential addresses are allowed for registration, but they must comply with local regulations), and a property ownership certificate or lease contract must be provided. If an enterprise has no actual office address for the time being, a legitimate agency can provide a "cluster registration address" or "business secretary address" that has been filed with the industrial and commercial department. Such addresses have guaranteed compliance and can be used for registration. However, it should be noted that the tax authorities may verify the authenticity of the address through means such as phone calls and letters. The agency will assist the enterprise in maintaining the address to ensure that it can receive verification information normally and avoid affecting business operations due to abnormal addresses.
