Use your own cell phone.

These demonstration numbers were established for the Federal Communications Commission in April 2024 and remain available so anyone can experience the basic concept for themselves.

1. Using your own cell phone, call either demonstration number shown above.
2. The demonstration treats the attempt as an unsuccessful emergency call. No emergency services are contacted.
3. Hang up and wait for the confirmation text.

The return text is the proof of concept. Your originating number was visible to the demonstration system even though the simulated emergency attempt never completed to a 911 center and, critically, a 911 call was never set up at all.

Demonstration only. These are not emergency numbers. In a real emergency, dial 911.
