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. For more complete coverage, please see the DELUXE Database.
