What is a Zip Code Directory?

A Zip Code Directory is a compilation of all the Zip Codes in the U.S. and their relevant information. The USPS makes changes monthly to zip code boundaries by adding or removing zip codes according to the current delivery route needs. While zip codes were created for the purpose of simplifying mail delivery, they serve a much larger purpose as they can provide useful data for search tools, customer location validation, and marketing insights. Our Zip Code Directory provides you with the raw data you need to build the tools to make your website or app successful.

Our Zip Code Directory provides unlimited potential by providing you with every current and active zip code in the United States. Never worry about data quality or accuracy since we update our database monthly with data we derive from the USPS (as a premier partner with them). Your directory will always be full and complete, and old Zip Codes are removed automatically with our fresh database that you can download each month.

Find all the Zip Codes located in a City or State or find the City name by looking up a Zip Code. You can perform limitless searches with the Zip Code Directory data, and quickly access the information you need.

Frequently Asked Questions

1. How does your zip code directory data differ from USPS data?

USPS data is the main foundation for our zip code directory data. As they update their data every month we provide the updated data to our customers. However, our data is more accurate and extensive as we append additional fields to improve the data for our customers.

2. Why should you choose ZIP Code Download over its competitors?

All ZIP Code data is not the same – Here at ZIP Code Download we update our database every month with all Zip Code changes made by the USPS, so you know you are getting the most accurate data available. We make our database useful and user friendly by enhancing with additional data such as area codes, latitude and longitude coordinates, and MSA Codes. Many of our competitors rarely update their data and use data that is months or even years old.
