The household registration number and household registration number on the citizen's household registration book are randomly assigned by the computer, and the same household does not print the household registration information at the same time, so the household registration number and household registration number are different. The number of households and people is the number counted in the computer when the public security organ manages the population information, which does not represent the personal information of citizens, and there is no need to worry about whether it is consistent with other people in the same household.

If it needs to be changed to the same one, the household registration book will be reissued, and the head of household needs to go to the local public security bureau to handle it. The general processing time is 5 working days.
