About Confirmation of my phone number!!!

[Hongyu0]

Hi, this is Hongyu [Personal information hidden], whose email address is [Email address hidden] or [Email address hidden],  I want to book a room today, and Airbnb needs to confirm my phone number. However, I typed the confirmation number from my message, and Airbnb said that the number has been used. But I just have this number only!!!!! How come?     Finally, after I tried a couple times, I`m no longer able to confirm my phone number. My phone number is [Phone number hidden].   I need to book the room as soon as possible, hoping this problem could be fixed quickly! Thank you.
