The U.S. Department of Transportation (USDOT) and its partners from all levels of government recognize the need for a National Address Database (NAD). Accurate and up-to-date addresses are critical to transportation safety and are a vital part of Next Generation 9-1-1. They are also essential for a broad range of government services, including mail delivery, permitting, and school siting.
Based on a minimum content approach that was a key recommendation from the NAD Summit, a schema as developed as part of the NAD Pilot. To date, USDOT has received address data from 23 state partners and has transformed it into the NAD schema.
Release 2 of the NAD is now available.
If you represent a state or local government and would like to include your address points in the NAD, please contact us at email@example.com.
