40 data fields per ZIP+4 record • Street-level centroid lat/lon (~80% coverage) • Census Block Group data • 48.5M records across all states & territories • Deluxe ZIP Code Database included (60 fields) • 62 state-level CSV files • 12 months of monthly updates • Free FTPS/SFTP automation • Redistribution license available • Phone & email support
Premium provides street-level centroid coordinates (~80% coverage) that are actively maintained, positioned on street centerlines. It's a major upgrade from Standard's legacy from/to coordinates (~60%, not actively maintained), and at $799.95/yr it's a fraction of Deluxe's $2,500 price point.
Premium includes the same 40 data fields, Census Block Group data, and Deluxe ZIP Code Database (60 fields with full demographics) as the Deluxe edition. The difference is geocoding method: street-level centroids vs. Deluxe's building-level centroids (~95%). For delivery route optimization, territory mapping, distance calculations, and most business applications, Premium's street-level precision is more than sufficient.
Every purchase includes 12 months of monthly updates at no additional cost. We publish fresh data on the 1st of every month, synced with official USPS updates. Download manually or automate via our free FTPS/SFTP access. ZIP+4 data changes frequently—approximately 5% of records update every month—so staying current is essential.
CSV (Comma-Separated Values) format. With 48.5 million records, CSV is the most efficient format—Excel and Access can't handle files this large. CSV works with all database systems (MySQL, PostgreSQL, SQL Server, Oracle) and programming languages. Data is split into 62 state/territory files for manageable imports. Total compressed size exceeds 1 GB.
The ZIP+4 database focuses on address ranges and delivery routes. To get city names, time zones, area codes, and demographics, join it with the included Deluxe ZIP Code Database using: ZIP+4.PreferredLastLineKey = ZIPCode.CityStateKey.
The Premium edition includes the full Deluxe ZIP Code Database (60 fields) with Census demographics, statistical areas, and enhanced location data—all at no extra cost.
Yes. Every Premium purchase includes free FTPS and SFTP access. Point your script or ETL pipeline at our server and pull fresh data automatically on the 1st of each month. No manual downloads needed—set it once and your data stays current for the life of your subscription.
