Latitudes, longitudes, and census data

ZP4 is able to automatically determine latitudes and longitudes, and Census Bureau tract and block numbers, for any ZIP + 4 code in the Geo database included with ZP4. Reverse lookups, such as finding ZIP + 4 records for a latitude and longitude, can also be performed. The Geo database is rebuilt monthly from Census Bureau TIGER shapefiles. If an address is not listed in the TIGER database, the address will not be included in the Geo database.
