Location confirmation

Good afternoon, 

I have just listed my property on booking last week and in the first 4 days we received loads of reservations but then all of a sudden my property has been closed while we are awaiting a letter with a pin code to confirm our address. 

Is there any way I can keep my property listed while awaiting this letter? 

From what I read it can take weeks to receive the letter and in the meantime we are missing out on a lot of bookings. Can someone help me please?
