4 Use Cases for ZIP Code Boundaries

on January 28, 2014 at 4:43PM

ZIP Code boundaries are the polygons that contain particular ZIP Codes. ZIP Code boundaries, as opposed to ZIP Code points, are helpful when identifying specific geographical regions, or setting up larger territories based on several ZIP Codes.

People are often surprised to learn that the US Postal Service (USPS) does not provide ZIP Code Boundaries. The USPS creates ZIP Codes, of course – but ZIP Code boundaries are only available through a third party.

ZIP Code boundaries are especially useful in the following four use cases…

1.  Real Estate Online Search

When home buyers and renters want to narrow down their property search results in an online portal, filtering by ZIP Code is often the preferred method. A search by ZIP Code gets consumers to the right location fast.

2. Direct Marketing

When companies want to deliver messaging to specific areas, ZIP Code boundaries are critical.

ZIP Code data is used by the direct marketer to send a mailer for skis to Flagstaff, AZ, not Phoenix, and a coupon for surfing lessons to Santa Barbara, CA, instead of Bakersfield. 5-digit ZIP Codes and ZIP+4 data give marketers the precision they need to target messaging at their most promising prospects.

3. 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 certain area. A ZIP Code is probably the second most frequently used filter in online search, behind specific place-names.

4. Sales Territory Mapping

Sales managers can improve sales numbers by segmenting their territories by ZIP Code. 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 Code Demographics: Super ZIPs, Better Schools

on November 12, 2013 at 12:43PM

Can a person’s ZIP Code indicate his or her demographic profile?

Increasingly, the answer is yes – especially if that person lives in a “Super ZIP.” Residents of Super ZIPs are among the most wealthy, well-educated groups in America, with a median household income of $120,000 and 70% of adults holding college degrees, according to the Washington Post.

More than one-third of Super ZIPs lie in the Washington, D.C. metro area, as the map below shows.

The Changing Face of ZIP Codes and Neighborhoods

ZIP Codes and neighborhoods are increasingly either lower income or higher income, rather than somewhere in the middle – a change from a generation ago.

“People of widely different incomes and professions commonly lived close enough [in the 1970s] that they mingled at stores, sports arenas and school. In an era in which women had fewer educational and professional opportunities, lawyers married secretaries and doctors married nurses. Now, lawyers and doctors marry each other.” (“Washington: A World Apart,” The Washington Post)

In 1970, 65% of families resided in middle-income neighborhoods. In 2010, that figure had dropped to 42%.

School Districts by ZIP Code

One result of socioeconomic stratification by ZIP Code is that more and more, better school districts and school attendance zones are clustered in wealthier ZIP Codes.

A study (based on Maponics school data) by the online real estate search engine Redfin showed that home prices in school attendance zones with top performing schools are often hundreds of thousands of dollars more expensive than homes that fall in school attendance zones with lower performing schools.

In some areas, it may be cheaper to send your child to private school than to find housing in a school district with better public schools, says a Brookings Institution study.
