A new version of the ZCTA based Zip code map was released today. This one is based on the Tiger/Line 2006FE database which was released on 12/12/2006. In addition, the online program is now using a more up to date version of the search database that will result in fewer misses on zip codes. See ZCTA Boundary Maps to give it a test drive.
Also available today for license is a new version of the database, same price as the old one at $1000. See Sales Data for more information on products and pricing.
