Clean, precise postal zip codes!

When only the best zip code data will do, there is our premium data and there are U.S. Postal Service generic copies. There is a difference! Generic ZIP code data, see why ours is better

We manually verify our postal code data! We have spent thousands of hours manually verifying our ZIP Codes and related data to ensure that it is the most accurate data possible! Government data, which others sell, is often outdated, inaccurate and not suited for many commercial applications.

We standardize the spelling of our place names. For instance, in the USPS file, they will have 'ST THOMAS' in one place and 'SAINT THOMAS' in another.

Our Latitude / Longitude points are precise! ZIP Code data boundaries change! We regularly check our coordinates to ensure that they are true center points. Most competitors just use government data. If you've already purchased a competitor's latitude / longitude product, go to our download page for our GeoCount tool which will compare their data to ours!

100% money back guarantee -- you can't go wrong!
