In order for an address to be recognized by the USPS, it must match a corresponding address within the official USPS database which you are able to access by visiting USPS APIs.
This address is set up, monitored, and cleaned out (or added to) by the US government on a regular basis. Most of the time this is done in conjunction with local municipalities, property changes and transfers, and the creation of new roads or mailing routes that are done in connection with local post office departments.
