A variety of companies rely on ZIP Code boundaries – from online real estate portals, to direct marketers, to search engines.
Although their applications are all a bit different, one aspect remains the same for every business: using current ZIP Code boundaries is critical. The older the ZIP Code boundaries, the more companies suffer in terms of efficiency, business intelligence, reputation and much more.
You might think staying up to date with ZIP Code boundaries is simple enough. How much do ZIP Codes change, anyway?
The answer might surprise you.

Sources of Updated ZIP Code Boundaries
Clearly, any business that relies on ZIP Code boundaries must be careful to stay updated. Even a few months without updates can leave you significantly behind.
But you can’t get the updated boundaries from the US Postal Service (USPS). Although the USPS creates, modifies and manages ZIP Codes, they do NOT provide ZIP Code boundaries.
So, where do you get them?
ZCTAs from the US Census Bureau
One option is to use ZCTAs, or ZIP Code Tabulation Areas, provided by the US Census Bureau. These are polygons created from tabular postal data.
The problem with ZCTAs is that they are only released every 10 years. Furthermore, the most recent release – 2010 – does not cover the entire United States.
Using ZCTAs can mean using outdated, incomplete postal data.
Another option is to use a commercial provider of ZIP Code boundaries.
The nuances in this option lie in frequency and cost. More expensive providers offer monthly updates – which keeps you covered with current data, but requires a relatively large investment. Less expensive providers only update every year or twice a year, which isn’t enough to be confident in the currency of your data.
