By inquiring the relevant information, it shows that the urban management department does not need to inform the merchants to report before opening the store, but the merchants must take the initiative to report to the urban management department, and they can officially open the store with the door approval certificate. Without the door-to-door approval certificate, the law enforcement department will issue a fine, and the normal operation can only be carried out after the fine is paid, and it is required to continue to reissue the door-to-door approval certificate. For specific information, please pay attention to official website for first-hand authoritative information.
