Today AND is pleased to announce that its ZIP+4 Boundaries are now available for ESRI’s ArcGIS Marketplace. The 5-digit ZIP Code plus a 4-digit add-on number identifies a geographic segment within the 5-digit area, such as a city block, office building, high-volume receiver of mail, or any other distinct mail unit.

Those extra four digits not only entitle you to USPS bulk mailing discounts but also increase the speed of delivery by as much as 2 days and by the same token help you to uncover hidden trends and insights within your customer database. With thousands of zip codes changes happening every year, it’s important to make sure you regularly update your zip code data with a database such our Zip+4 database.

So start visualizing your customer base and understanding trends, behaviors and preferences within a micro ZIP+4 area today. Click here to for your free sample data of San Francisco county.
