Legal analysis: If one of the dual household registrations is canceled and the other is frozen, you need to bring your ID card, household registration book, and village committee certificate. It is best to write a letter of repentance admitting your mistake. Because a person can only have one household registration, it is illegal to have dual household registrations.

Legal basis: "Regulations on Household Registration of the People's Republic of China"

Article 4 The household registration authority shall establish a household registration book.

In cities, on the water and in towns with public security police stations, each household should be issued a household registration book.

In rural areas, household registration books are issued to cooperatives as a unit; household registration books outside cooperatives are not issued.

The household registration book and the matters recorded in the household registration book have the effect of proving citizenship.

Article 5 Household registration is based on household units. Those who live in the same place as the person in charge are considered to be one household, with the person in charge being the head of the household. A single person living alone has his own household, with himself as the head of the household. Those who live in agencies, groups, schools, enterprises, institutions and other units or in public dormitories must open one household or separate households. The head of household is responsible for reporting household registration in accordance with the provisions of these regulations.

Article 6 Citizens should register as permanent residents in the place where they usually live. A citizen can only register as permanent residents in one place.
