A Word About ZIP Codes – ZIP5, ZIP3, ZCTA, and Points

To build a ZIP Code using MapBusinessOnline click this link & register

MapBusinessOnline includes a map layer of ZIP5 codes for spatial reference to ZIP code boundaries.  US Postal Service (USPS) ZIP code boundaries are used as the basis for territory construction.  By applying MapBusinessOnline map layers like ZIP5 codes, states and counties as the basis for territory construction MapBusinessOnline is able to incorporate data into territory analysis views. Analysis that might include demographic categories or user imported data.

MapBusinessOnline Standard subscriptions also includes access to ZIP3 or 3 digit ZIP codes through the Add Map Layer button.  3 digit ZIP codes represent larger areas around the nation.  A 3 digit ZIP code is simply the first three digits of a 5 digit ZIP code. So for Massachusetts, the 3-digit ZIP code numbers would include 021 and 019. The 5 digit ZIP code where I grew up was 01966. Go Vikings!

3 Digit ZIP Codes






Census ZCTA ZIP Codes

First time MapBusinessOnline users will note that the ZIP code layer delivered with a new subscription is set to the default of ZCTA ZIP codes from the US Census Bureau. ZCTA stands for ZIP Code Tabulation Area. A business mapping software user can change the ZCTA layer to the USPS standard ZIP5 Code layer by clicking the Edit Properties Gear in the Map & Data toolbar. Choose the ZIP Code tab and the Drop Down to USPS ZIP Codes With Fillers. CTA ZIP codes will provide more accurate estimates for certain Census categories.

ZIP Codes with Fillers

I recommend selecting the ZIP5 codes with fillers because that ZIP5 code map layer option will automatically accommodate national parks and other areas where ZIP5 codes do not exist. This avoids lots of territory holes in your business map, especially out west. So if you notice your sales territory maps have white spaces in them, the fill isn’t consistent, it is probably from lack of fillers. Remember, if you do change to ZIP5 codes with Fillers the fix is not retroactive. You will have to reconstruct territories to fix those holes.

ZCTA ZIP code and USPS ZIP5 code boundaries generally reflect the same boundaries.  But there can be some differences. ZCTA is a Census Bureau version of ZIP codes used for tabulating Census collected data. ZCTA ZIPs are more closely aligned with Census block areas, where the USPS postal codes are more focused on mail delivery and other USPS concerns.  ZCTA ZIPs are designed to focus on populated areas. Rural areas may not have associated ZCTA ZIP codes. Read more about ZCTA ZIP codes here.

MapBusinessOnline first included ZCTA Census based ZIP codes because they are freely available from the Census Bureau, making them appropriate for use with our free 1-month trial of the product.

ZIP5 Boundaries vs. Points

ZIP5 codes are generally attributed to the US Postal Service. USPS ZIP codes in Map Business Online map layers are boundary ZIP codes.  MapBusinessOnline boundary ZIP codes are used to create territories and areas of interest. A ZIP Code radius search of a ZIP code layer returns a collection of boundary ZIP codes for export.

Point ZIP Codes over Boundary ZIP Codes

Point ZIP5 codes represent large USPS mail stops for big facilities like military installations, hospitals, assisted living centers, or sky scrapers.  The USPS ZIP Code list includes 33,238 boundary ZIP codes and 7,785 point ZIP codes. A complete list of Boundary and Point ZIP codes is available in the MapBusinessOnline Public Data from the Server, accessed through the Plot Data button on the master toolbar. Read more about Boundary and Point ZIPs.

A common question from MapBusinessOnline potential users is, “How do I map my ZIP codes?” While all of this ZIP code information may feel a little overwhelming, please keep in mind that ZIP codes are a man-made organizing tool to help deliver the mail efficiently. ZTCA’s are a twist on that tool to help the Census Bureau compile data, and boundary and point ZIP codes are simply differentiating areas from large buildings.  With all that in mind, go build yourself a ZIP code map.
