Zip Code data

Established in 1992, we started out selling programming tools, including a simple 5-digit zip code lookup file. In 1995, we became the first company to market zip code data on the Internet! We quickly received requests for additional countries like Canada ZIP Codes and other add-on products. Soon, data products and related tools and services became our only business.

Today, we have thousands of clients, from small businesses to most of the Fortune 100! Our clients require quality ZIP Code lookup data and realize that there is a vast difference between government data and our custom data products. We strive to ensure the best data possible!
