An address I used to live at was in an unincorporated area that the county had put basically zero effort into giving addresses. The street had a sensible name that everyone who lived nearby called it. Let's suppose it's "Thataway Rd" (I am anonymizing all components of this address). But that name wasn't in the USPS database. They called it something like "CC04". The house at the end of the road was number 50. The road was long and had an increasing number of houses built on it, which used all the numbers up to 48, and then the houses after that became 48B, 48C, 48D, ... 48Q, 48R, 48S... So if you made the address by following the house number with the street name, the address would have been 48R CC04. Which nobody would recognize as an address. The post office suggested "CC04 Box 48R", which if you filled it into a Web form, would trigger special handling for PO boxes. On top of that, Google had the ordering of the house numbers backwards, so Google Maps would send people to the wrong end of the long street. Clearly nobody was happy with this, but I credit the emergency dispatchers with finally pushing through to give everybody a reasonable address based on what they already called the street. Through their effort I finally lived at 14 Thataway Rd instead of 48R CC04.
