Your Avis Worldwide Discount (AWD) number is a unique code that applies specific corporate, organization, or promotional discounts to your car rental. If you are an Avis Preferred member, your AWD is typically saved in your online profile; you can find it by logging into the Avis website or mobile app and navigating to the "My Account" or "Loyalty" section. If you received a discount through a partner like AA, Costco, or a corporate employer, the code is usually provided in the "Benefits" section of that organization's member portal. You can also find AWD numbers in Avis promotional emails or on the back of physical membership cards. If you are still unable to locate it, calling Avis Customer Service (1-800-331-1212 in the US) with your membership details will allow an agent to retrieve the active code associated with your account for your next 2026 booking.
