ZIP Code Database

Quality Latitude and Longitude Included

This high-end, 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 database possible. It is extremely clean due to our robust verification process. Without scrubbing, postal databases are filled with thousands of erroneous records, inconsistencies, and duplicates. Our extensive algorithms have matured for 30 years and are continuously updated as changes occur.

Anytime a ZIP Code boundary covers more than one city, this file has each city listed as a separate record with the primary city clearly marked. That makes around 60,000 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.

Meaningful Latitude and Longitude Database

We target population based center points instead of geographical centers that often fall in uninhabited areas such as parks, business districts, lakes, golf courses, etc. For example, the geographically center of ZIP Code 10023 would fall in Central Park! We guarantee that our lat/long is better than you can find elsewhere.

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.

Methodical Verification

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.
