Our USPS Zip Code Polygon database has been updated! The new database is current as of 09/2007 and contains 31,581 zip code areas. Combine this database with our zip code bounding box product and you'll have a complete zip code depiction package. The new database comes as either shapefiles (one per state) or as a tab delimited file in PostgreSQL dump format. Importing this data into your MySQL, SQL Server or other database system is easily accomplished using the PostgreSQL format, your GIS program is probably best with the shapefiles.
The price for this product is $5000.00 and updates are $1250.00 available each quarter. Updates are not mandatory and contain a full database, so update only on your schedule, not ours.
If you've purchased a license to our ZCTA database already, there is a special price on these polygons of $4000.00 for a limited time (expires 12/31/2007).
