An Avis Wizard number is the easiest way to manage your Avis reservations. A Wizard number makes reservations easier and faster because it lets you store your travel details into an online profile. You can quickly and easily track, view, modify or cancel your upcoming reservations, and get receipts for past rentals. It’s free and easy to get one. Just select the “I Don’t Have a Wizard Number” option on the Rental Health Day enrollment form and you are on your way. You will receive a Wizard number immediately.
