The national general interface for government affairs is provided by the National Citizen Information Inquiry Center, a subordinate institution of the Ministry of Public Security, and the database used is backed up from the intranet of the Ministry of Public Security for external verification and charging. But this database can't be synchronized with the intranet of the Ministry of Public Security. Some new identity cards or some old identity cards in remote areas have not been updated, which leads to the situation that the relevant interfaces accessing this database cannot find information. This situation can only be said to be unlucky. Under normal circumstances, you can provide household registration books, passports and other materials instead. If it really doesn't work, find Guo Zhengtong yourself. They will submit updates, but they are also slow. Complain if you don't handle it.
