A ZIP Code is a postal code used by the United States Postal Service (USPS) in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; it was chosen to suggest that the mail travels more efficiently and quickly (zipping along) when senders use the code in the postal address.

Note: Approximately 40-50% of records in the STANDARD Database do not contain Latitude/Longitude data; This is partly due to the fact that many are 'point' ZIP Codes which have no geographical boundaries. Examples include: P.O. Box Only, Military, Single Business, and Government ZIP Codes. Any remaining missing Lat/Lon data is a function of the Tiger data always trying to play 'catch up' with the U.S. Postal Service changes.
