How many years do you usually keep the original household registration book?

Legal analysis: the original household registration information has no clear retention period. In actual management, the public security organs will not take the initiative to destroy the original household registration information. So if you need to inquire about relevant data, you can go to the business department that was handled at that time.

Legal basis: Article 21 of the Archives Law of People's Republic of China (PRC), the principle of appraising the preservation value of archives, the standard of preservation period, and the procedures and methods of destroying archives shall be formulated by the national archives department. It is forbidden to tamper with, destroy or forge files. Unauthorized destruction of documents is prohibited.
