1. Household registration inquiry is a convenience service carried out by public security organs. Public security organs can know the basic information of the population through household registration inquiry, such as family members, residential address, etc.
2. If the police call to check the account, it may be that they need to know relevant information when performing their duties, such as investigating cases and verifying their identities. In this case, we should actively cooperate with the police and provide relevant information and proof materials.
3. In some cases, the police may also confirm the identity information and address information of citizens through household registration inquiry, so as to better safeguard social order and people's safety.
In short, when we receive a phone call from the police asking to check the household registration, we should keep calm, actively cooperate, provide relevant information and proof materials, and ensure that our legitimate rights and interests are protected and maintained.
