Ninety-five percent of Americans now reside in areas where wireless 9-1-1 service includes the delivery of the user’s callback number and estimated caller location to the appropriate Public Safety Answering Point (PSAP), a
capability known as Phase II Wireless Enhanced 9-1-1 (E9-1-1) service. This number represents a five percent increase from a year ago. Another positive development is that more than ninety percent of individual PSAPs are
now Phase II capable, over an eight percent increase from a year ago.

While this progress is certainly welcome, almost twenty percent of the nation’s 3,135 counties, primarily located in rural areas, still cannot provide this critical service to their residents and visitors. The Wireless E9-1-1 statistics, published on the NENA website measure the number of counties, individual PSAPs, and total population covered by Phase I and Phase II wireless location technology. Phase I includes delivery of the caller’s phone number and identification of the cell tower receiving the 9-1-1 call. Phase II includes delivery of the caller’s phone number and estimated caller location.

The DOT Wireless Implementation Project has been completed but NENA continues to compile up-to-date statistics. Detailed state and county statistics can be found on the wireless deployment section of the NENA web site at
