To set up a rental reservation by phone simply call 1-800-RENT-A-CAR and give the booking agent the Billing Number# 17200313 as well as your company Corporate Discount number (CD# XZ21009). To set up a rental reservation by TMC simply instruct your booking agent to include your Billing Number #17200313 in their “ID” field as well as your Corporate Discount number (CD# XZ21009). To set up a rental reservation online, go to Reservations and enter the location, date and time and your Account# XZ21009 for the rental and click "Continue" to search for available vehicles. Choose the car class that’s preferred. The next screen will be the Extra's screen, click on "Continue to review" button. On the next screen, put in the renter’s name, phone and email address. Underneath that, it will ask you to confirm if this is a business rental, click "yes". It will then ask you if you are authorized and choosing to bill your company for this rental. Click “Yes”. This will prompt you to enter the billing number in a new field that opens. Enter your Billing Account# 17200313 and click on “continue”. On the next screen, click on “Reserve Now” to complete the reservation. Once you have placed the reservation either by phone, TMC or online, your employee will need to simply give their name, confirmation number from the reservation, and present a valid driver’s license when picking up the vehicle…they will NOT need a personal credit card in order to complete this transaction. We recommend providing these numbers only to those individuals in charge of making reservations for your company…it should not be given to all employees. Any employee or previous employee making a reservation via internet or phone, using this billing number for an unauthorized rental will be the responsibility of your company.
