History of US ZIP Codes
USPS changed the ZIP code system in 1983 to include the new ZIP+4. This uses a basic five-digit code plus four additional digits to identify a small delivery segment. This ZIP+4 code is calculated automatically when the mail is sorted and processed.
Each Post Office Box has its own ZIP+4 Code & since there is a variance, the Code must be looked up individually for each Post Office Box. Also, not every USPS deliverable address have a ZIP+4 code assigned to them. Geocoding lookups or address validation are used for these addresses.
