I live in an agricultural area in Hawaii with large lots and crappy dirt roads. USPS do not offer mail delivery here. Because of this, my home address is listed in public databases in no fewer than 3 different zip codes. Trying to get my address identified in a product when it demands a home address is always spin of the roulette wheel as to which one (if any) will work. It would be lovely to get an official answer about which zip code my lot falls in, especially if other databases start using the definitive value!
