ZIP Code Database - Basic

Our 2019 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.
