Why it matters

• Instant emergency localization: Real-time coordinates speed up dispatch and response.
• Simplified integration: We handle PIDF-LO formatting and delivery.
• Production-ready for connected devices: Ideal for fall detection, crash alerts, lone-worker safety, and more.
• Nationwide coverage: Seamless routing to the correct PSAP across the U.S.

Example use cases:

• Wearables and health monitors: Automatic fall or anomaly detection calling 911 with precise location.
• Vehicle telematics: Crash events trigger emergency calls with exact coordinates.
• Enterprise safety and lone-worker: One-tap SOS with accurate outdoor location.
• Consumer safety apps: In-app 911 with built-in location fidelity.

Getting started

1. Sign up / log in to the Telnyx Mission Control Portal.

Geolocation: <cid:[email protected]>
X-Latitude: latitude
X-Longitude: longitude

Example

Geolocation: <cid:[email protected]>
X-Latitude: -45.08
X-Longitude: 30.345

5. Test to validate PIDF-LO delivery and location readout.
