For companies that use identity information to register, measures can be taken to cancel their registration. According to the relevant regulations, the market supervision department should actively respond to the lawsuit, and the market supervision department that made the registration decision is responsible for canceling the registration. If the registration authority has changed, the registration authority is now responsible for cancellation. If the basic facts of impersonation registration are clear, or the company and relevant personnel can't get in touch or don't cooperate with the investigation, and no interested party raises any objection during the publicity period, the registration authority considers that the impersonation registration is established and shall make a decision to cancel the registration according to law.
