ZIP Code Database - Basic

Does Not Include Latitude and Longitude

Our 2021 Standard ZIP Code database (non-geocoded) is an Enterprise Class product well suited for commercial applications. Our processes for data cleansing and standardization make it vastly superior to most U.S. Postal Code databases on the market. Beyond USPS data, we cross-reference multiple sources to obtain the most accurate robust database possible. Our accuracy comes from 20 years of perfecting our methods to eliminate duplicates and create uniformity. Other postal databases can have thousands of duplicates, different spellings for the same name, and numerous incorrect records

If a ZIP Code boundary spans more than one city, each city is listed as a separate record making around 57,500 legitimate U.S. records. It has no duplicates but it is thoroughly complete. Its is standardized to ensure consistent spellings and uniform naming conventions. Mouse-over database specs (right) for field level detail.

Standard Place Names

Our US ZIP Code 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 their ZIPCode database.

Methodical Verification

Our precision and accuracy is a result of manual verification and comparing our databases with multiple resources. Once an anomaly has been identified, we refine our algorithm to account for it. We've been perfecting this since 1992! Learn more: view the ZIP Code Data Product Documentation
