ZIP Code Database - Latitude and Longitude
This Enterprise Class ZIP Code database is dramatically superior to the many repackaged U.S. ZIP Code database products on the market today. We use multiple sources to obtain the most accurate robust database possible. It is extremely clean due to a continual manual verification process. Our process for eliminating duplicates is unmatched. Normal postal databases will have thousands of duplicates, different spellings for the same place, and numerous incorrect records. You will not find that to be the case with this product.
Anytime a ZIP Code boundary covers more than one city, this file has each city is listed as a separate record. That makes around 57,500 legitimate records for the United States. More records simply means more duplicates or errors. This file is very clean and appropriately lean. Its data is standardized to ensure consistent spellings and uniform naming conventions.
Not only is our base data superior, but our latitude and longitude is as well.

Meaningful Latitude and Longitude Database
We target population based center points instead of physical centers that often fall in uninhabited areas such as parks, business districts, lakes, golf courses, etc. As shown
here, ZIP Code 10023 has a star for the population center point. Had we used a physical center,
it would be in Central Park!
Standard Place Names
Our US ZIP Code Latitude and Longitude Database goes to great lengths to assure all the cities and towns are consistently labeled. By eliminating deprecated and misleading city records, the overall record count is reduced. Other products may have thousands of erroneous records added to the database.
Our precision and accuracy is a result of manually verifying the data and comparing it with multiple resources. Once an anomaly has been identified, we refine our algorithm to account for it. We've been perfecting this since 1992!
