Addresses for the Nation - Pathways from Restricted Data to Open Data

August 18, 2022

Accurate and up-to-date addresses and their locations 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. In addition, the data can help enable critical applications including public health tracking and disease vector control, natural disaster response, transportation planning, construction/improvements notification, and provision of affordable housing. The National Address Database (NAD) is a unified collection of authoritative address points integrated from partners across the country. In most cases, the data is collected and maintained at the tribal or local governments, the data authorities, and aggregated to the state level before submission to the NAD.

While participation is strong, not all states with address data have been able to become NAD partners. In some cases, there are policies in place that restrict data from being shared publicly. Overcoming these restrictions is important – and possible.
