To actually get the list of zip codes costs money, either from the USPS or other sources. However, by repeatedly typing in zip codes into the zip code locator as USPS.com I found out the valid upper and lower bounds.

    Don't new codes get added? In other countries valid/invalid codes aren't contiguous sequences. I'd assumed that the lower/upper bounds were part of the spec? If not I'm not sure I'd rely on all the codes outside those bounds being invalid if it were me.
