The household registration book has the legal effect of proving citizenship and family members, and is the main basis for household registration authorities to conduct household registration and verification.

Legal basis: Article 17 of the Regulations on Household Registration in People's Republic of China (PRC) stipulates that if the contents of household registration need to be changed or corrected, the head of household or himself shall report to the household registration authority; If it is verified through examination, the household registration authority shall change or correct it.
