Do foreign customers need to provide passports before booking hotels?

You can use it, but it is not necessary. You don't need it when you book it. When you stay, you must register with your passport. This hotel is a profit-making organization. You can book a room directly with your ID card, register after the customer arrives, and then give the room card to the customer.

Hotel registration has two purposes. First, mainly for safety, the identities of all registered customers will be uploaded to the public security system. Second, five-star hotels register their identities in order to provide convenient services.
