National Address Database

The National Address Database (NAD) is a crucial initiative by the U.S. Department of Transportation, designed to consolidate and standardize address information nationwide. This resource serves as a foundational dataset for various geospatial applications, public services, and emergency response systems by offering a consistent view of addresses across different jurisdictions.

The NAD aims to improve data interoperability and accessibility, providing a valuable public good for government agencies, businesses, and the public. Users are encouraged to sign up for announcements to be notified when new releases of the database become available for download, ensuring access to the latest data.

By centralizing address data, the NAD facilitates more efficient geocoding, routing, and location-based services, underscoring its importance for modern infrastructure and planning.
