“Why are ZIP Codes Missing In My Database?”- Wednesday, May 23, 2012
Frequently, customers are concerned that data is missing from their database - as they should be. Here at Zip Code Download, we highly value accurate and reliable data. Above all, we hope that our database is current. The key point is that because the USPS is constantly changing their data, some ZIP code are literally removed from their database.

There are many reasons for the removal of ZIP codes that we won’t go into. However, it is important to remember this fact.

Your customers may worry that you have unreliable data. However, you must remain confident that your data is in sync with the USPS - the ones in charge of ZIP codes.

If you are unsure about your data, the USPS has a very neat feature that allows you to look up a city based on a ZIP code. To do this, visit www.USPS.com and select “Look Up a ZIP Code” under their “Quick Tools” menu on the left side of the page. Then select “Go to Full-Page Version.” Once there, click on the “Cities by ZIP Code” tab. Then enter the ZIP code in question.

If the ZIP code has been removed, you will get a message saying that the ZIP code is not a valid ZIP code. (See attached screen shot). Please do this before contacting customer support.
