Required for non-hotel stays
Complete accommodation registration
Hotels normally register guests. If you stay in a private home, rented flat or other non-hotel accommodation, register within 24 hours. Shanghai provides online self-declaration as well as police-station or community service-window routes. The guest, host or accommodation provider may handle the declaration.
A Chinese mobile number is useful but is not stated as a legal prerequisite in the official guidance. Keep the registration result: it may be requested later.
