Hi @Marie82
I recently received a request from a Chinese guest from mainland China. His profile name is a certified mobile user number. It appears he is relatively new with AirBNB. I have to ask him a series of questions such as his name, purpose of his trip, flight arrival time, if he had read the house rules, etc. and explained our check in procedure.
I also suggested that he should update his profile by putting his real name, not a certified mobile user number XXX, so future AirBnB hosts would know he is who he is, . He accepted my advice and updated his profile name promptly.
Hope this help,
Kit
