ZIP code and postcode data

ZIP Code boundaries enable direct marketers to target the right prospects, managers to develop sales territories, homebuyers to locate property listings and users to enhance their local search by proving ZIP code boundaries and centre points for every ZIP code in the United States.

  • Includes all 50 states, the District of Columbia and Puerto Rico
  • Zip Code to neighbourhood correspondence data based on Neighbourhood Boundaries
  • Monthly and quarterly updates
  • Not available from the USPS
  • Availability: SHP, TAB, WKT, MySQL, PostGIS, KML



  • Real Estate Online Search: When customers want to narrow their property hunt online, searching by ZIP code is often the preferred method. ZIP code data gets buyers to the right area fast. When combined with Neighbourhood Boundaries, property searches become even more meaningful. 
  • Direct marketing: When companies want to deliver messaging to specific areas, knowing correct ZIP Code boundaries are critical. 5-digit ZIP Codes and ZIP+4 data give marketers the precision they need to target messaging at their most promising prospects.
  • Search/Local search: Searches conducted by ZIP Code give users an additional way to narrow their results when looking for products and services in a specified area. A ZIP Code is the second most frequently used filter in online search, behind specific place-names.
  • Sales territory mapping: For years, a variety of industries have relied on ZIP Code areas quilted together to form regions in which they assign a person or group to represent their business and sell their products.


Zip+4 centroids offer greater detail than ZIP code boundaries alone can. When businesses want even more precise targeting they turn to ZIP+4 Centroids as a cost-effective and efficient source for geocoding millions of addresses, based on their ZIP+4s, to accurate locations.

  • Coverage for all 50 states and the District of Columbia, Puerto Rico and US Military APO/FPO
  • Not just repackaged from the USPS: ZIP+4's are initially represented by the US Postal Service as a ZIP+4 low value and a ZIP+4 high value (for example, 20001-0001 to 20001-0486). Pitney Bowes expands these to represent the individual ZIP+4 values included within the ZIP+4 range
  • Monthly and quarterly updates available: ZIP+4's are dynamic as about 100,000 additions and deletions occur every three months. Pitney Bowes releases updated ZIP+4's every quarter, enabling our customers to keep current with the latest postal changes.


  • Pinpoint your target consumers with precision: ZIP+4s represent a smaller set of households. That means they can be used to narrow results for smarter direct mail efforts.
  • Learn where customers live to improve marketing analysis: Because our database includes centroids, businesses can use them for marketing research to discover where their customers live. ZIP+4s give you a clear idea of how far people are willing to travel.
  • Indispensable for geocoding: Businesses use ZIP+4s as a cost-effective and efficient source for geocoding millions of addresses, based on their ZIP+4s, to define accurate locations.
