40 data fields per ZIP+4 record • Building-level centroid lat/lon (~95% 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 • Phone & email support
The key difference is geocoding precision. Deluxe provides building-level centroid coordinates (~95% coverage) centered on actual structures, compared to Premium's street-level centroids (~80%) and Standard's legacy from/to coordinates (~60%, not actively maintained).
Deluxe also includes the Deluxe ZIP Code Database (60 fields with full demographics), Census Block Group data, and the highest accuracy matching available. It's the best choice for enterprise delivery systems, last-mile optimization, GIS applications, and any use case requiring mission-critical precision.
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 Deluxe 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 Deluxe 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.
