How long will it take to delete the record of opening a house with an ID card?

3 years or permanent preservation. The check-in record in the hotel will be kept in the public security system for 3 years, and the check-in information will be automatically deleted after 3 years. At the time of check-in, regular hotels require customers to hold their ID cards for face-brushing authentication on the public security network, and the check-in information of consumers will be immediately filed on the public security network. If it is a small hotel that is not connected to the public security organ, the paper registration record of room opening shall be kept for at least 3 years and kept for future reference at any time. If the hotel is related to the public security organ, the check-in record will always be kept in the database.
