How long does it take for hotel room records to be found?

Three years later. Hotel room records will be kept in the public security system for 3 years, and the room information will be automatically deleted after 3 years. Within 3 years, the public security system has the right to query the user’s room information. Because the customer's check-in record has been recorded in the server by the public security system, even if the check-in record is cleared in the hotel, the public security system can still query it. There are two main types of open registration for hotels: 1. One is the relatively backward paper registration. Paper hotel registration records will be required to be kept for 3 years for easy inquiry at any time. From the perspective of financial management, paper as a business voucher must be kept for 15 years; 2. The other is online registration, which is more common in cities. As long as the system memory is large enough, it can basically be saved permanently from a technical point of view.
