We Scrub...

Low-end databases may have thousands of duplicates, different spellings for the same place, and numerous incorrect records. This database is impeccable.

Some ZIP Codes span multiple cities. This database lists each city-to-Zip occurrence as a separate record, making around 60k clean U.S. records; more means duplicates. The database is standardized to ensure consistent spellings and uniform location naming conventions.

Not only is our core data superior, our latitude and longitude is too. PDF - what makes our ZIP Code database better.
