Anonymous Unique Code I need a unique code to verifi my location, but I have not recieved any code so do not know how to continue? Thanks 10 M Adamopoulou Hi! Candy and welcome to the Partner Community. I think it would be best if you send a message request through your Extranet inbox directly to booking.com. Wish you luck... B. Community Admin Hi Candy Buttle Thank you for your post! The unique code is sent from Amsterdam to the property address of your accomodation. First of all, we kindly ask you to make sure that you have registered it correctly. If from the day you finish the registration, 10-15 business days have passed, we ask you to go to your Home Tab, and request a new one, that will be resend automathically.
