Maponics Postal Data
Zip+4 Code Centroids
Maponics ZIP+4 Code Centroids includes over 51 million records detailing the 5-digit ZIP code and the 4-digit extension (AABB) representing the ZIP Code Sector (AA) and ZIP Code Segment (BB). The inclusion of the 4-digit ZIP Code extension is used by the United State Postal Service to faciltate efficient mail handling and delivery.
Maponics' proprietary process builds the ZIP+4 point product by matching each ZIP+4 address collection to street segments and offset to the correct side of the street. Finally Maponics implements a rigorous Quality Control process to ensure the ZIP+4 product is of the highest quality. This QC includes steps that check for and remove any duplicate ZIP+4 values as well as ensure proper data field representation.
A ZIP+4 can represent one side of the street, a floor in a building, or a specific Post Office Box. PO Box ZIP+4's are initially represented by the United States Postal Service as a ZIP+4 low value and ZIP+4 high value, e.g. 200010001 - 200010486. Maponics expands these ranges to contain all the included ZIP+4 values within the initial ZIP+4 range set.
