In addition, if there is a case involved, you can check the driver's license and hotel registration records. At present, the management of public security network is very strict, and special digital certificates are needed to search information online. As for personal property information, loan information, communication information, etc. Can't find it on the public security information network. The investigation can only be conducted by the police handling the case through the banking and communication departments. These investigations can only be carried out with the approval of the head of the county-level public security department, and only criminal cases can be handled.
