I'd note that many of these codes have been publicized for a long time here and elsewhere without change by Avis. Employee/family and other internal codes appear to have been most vigilantly protected, along with some that appear to have been heavily abused in high-cost, touristy and high-traffic (pardon the pun) areas (Disney, Florida and Hawaii come to mind). But codes with a large legitimate user base here in the US (Costco, AAA, travel agencies, hotels and airlines) seem unlikely to get changed; too much trouble, maybe the sponsor gets a kickback-type benefit. Corporation's codes do give me the willies, because internal accounting/travel folks could audit their use and catch non-employee users' name (albeit after the rental's complete) - those seem to me most likely to get changed or have an ID requirement enforced due to abuse, and I stay away from them.

Just my 2 cents.
