The National Emergency Address Database:
Enhancing Indoor 9-1-1 Location Accuracy

Dialing 9-1-1 is the most important call you make, and we all share the goal of enhancing the 9-1-1 system. Consumers, public safety officials, and policymakers expect 9-1-1 professionals to provide first responders with accurate location information of a wireless 9-1-1 caller. Wireless calls placed indoors can present additional challenges to public safety, especially where the street address and additional information like the floor, office suite, or apartment number may be needed to locate a wireless 9-1-1 caller.

That's why CTIA created the National Emergency Address Database, also known as the NEAD, in collaboration with public safety community representatives. By leveraging commercially-deployed Wi-Fi Access Points and Bluetooth Beacons—reference points mapped to street addresses and additional location information, the NEAD will help 9-1-1 professionals to locate wireless 9-1-1 callers more quickly and accurately.

To make this effort a success, the NEAD seeks partnerships with reference point owners—cable companies, enterprises, public institutions, and any entity that owns or manages many wireless access points—to contribute this data to the NEAD and enhance our country's 9-1-1 system. You provide your reference points, and the NEAD provides you with everything you'll need to participate —and most importantly, everyone gets an improved 9-1-1 experience.

About the NEAD

CTIA created the NEAD to comply with the FCC's 2015 Order on location accuracy. The NEAD serves as a resource of registered wireless access points that help locate someone calling 9-1-1 from a mobile device. West Safety Services, with a history of providing 9-1-1 services, serves as the NEAD vendor.

How the NEAD Works

When you call 9-1-1 on a wireless device, your device scans for nearby Wi-Fi access points and Bluetooth beacons to help determine your indoor location. If those access points are in the NEAD with a verified street address and any additional information like the floor, office suite, or apartment number, that location information can be sent to a 9-1-1 call center.

NEAD Platform Design

The NEAD is a fault-tolerant, geo-redundant, and resilient platform, offering real-time performance for 9-1-1 calls nationwide. The NEAD is based on ATIS standards and is ISO 27001 Certified.

NEAD Information Privacy

The NEAD incorporates privacy and security by design. Address information submitted to the NEAD will only be used for 9-1-1 purposes. Wireless carriers must certify to the FCC that they will not use the NEAD or associated data for any non-9-1-1 purpose, except as otherwise required by law.
