ZIP Code Boundaries Data

GreatData is a reseller of what we feel is one of the most meticulously created ZIP Code Boundary database on the market. It is ideal for displaying ZIPCode Boundaries on a map.

This can also be used in social networking and local search applications. Internally we used this product to create our ZIP Code Bounding box data which is used in location-based service (LBS) applications. It's currently used in a very popular phone app.

zip code boundaries The U.S. Postal Service does not abide by strict ZIP Code map boundaries. Instead, a ZIP Code is assigned to an address based on the USPS mail carrier's route (some even cross state lines). In densely populated areas a ZIP Code boundary is usually pretty clear. However, in some suburban, and especially in rural areas, ZIPCode Boundaries can be subjective.
