Dynamap/ZIP+4 Centroids are a cartographic representation of the 60+ million deliverable USPS ZIP+4 records. With the addition of a census block correspondence file, Tele Atlas creates the link between census and postal geography to create the Dynamap/ZIP+4 Centroids & Block Correspondence File product. The ZIP+4 product attaches census data and latitude/longitude coordinates to USPS ZIP+4 records by locating the street segment associated with the ZIP+4 record in the Tele Atlas street database.


The Dynamap/ZIP+4 Centroids & Block Correspondence File product is designed principally for use with mailing and geocoding applications where customers need to locate individual USPS ZIP+4 records to retrieve census and coordinate information.


  • High linkage percentage between USPS ZIP+4 file and TeleAtlas streets database: Accurate, fast geocoding at the ZIP+4 level
  • Additional census and latitude/longitude information provided not found in USPS files: Greater information about particular USPS ZIP+4s
  • Block Correspondence File provides link between census and postal geography: More detailed information about specific ZIP+4s, such as block level census data and coordinate information
  • Enhanced version offers “ranged” records: Reduces file size and look-up time. Handles multiple block correspondence
  • Centroids provided at the ZIP+4, ZIP+2 and 5-Digit ZIP Code levels: Provides multiple levels for locating address associated with a ZIP+4, increasing address match rates
  • ZIP+4 Centroids product built from Tele Atlas’ comprehensive streets database: Insures accurate, up-to-date, comprehensive information for superior geocoding results. Accurate overlay with other Tele Atlas products.
