Legal analysis: whether it will be replaced consistently depends on the type of household registration book replaced by the parties. If the party concerned redeems the household registration book without moving the household registration or opening a separate account, the account number will not be changed; However, if the party concerned does not move into the household registration and set up a separate household registration, the family members, household registration number and household head will all change.
