Many users confuse the name the Post Office delivers main to (e.g. Van Nuys, Hollywood) as a legal city (in this case Los Angeles), when they are a postal city. The County contains 88 legal cities, and over 400 postal names that are tied to the ZIPCodes. To support useability and geocoding, we have attached the first 3 postal cities to each address, based upon its ZIPCode.
