I, too, am under 25 and frequently rent cars for business travel. My firm's AWD # does not, for some reason, include the under-25 provision, but when the agent does a search by the firm's name, he/she eventually stumbles across the note that allows under-25 rental. Also, use the same credit card each time, because AVIS tracks by credit card number. After they clear up the under-25 issue the first time, they can always verify your eligibility by checking your credit card number.
