If your company or organization has negotiated special rate privileges with Wyndham properties, you can reserve a room using your corporate ID number. This ID number is provided by Wyndham, but must be obtained from your company's travel office. Wyndham does not provide corporate ID numbers to guests for security purposes. Whether reserving a room by phone or over the Internet, provide your corporate ID number to receive the special rates provided to your organization. Some companies restrict employees from making their own reservations, so if you can't book a room with your corporate ID number, verify your company's reservation policies.
