Dauphin County operates an Enhanced 911 (E911) system and is the only recognized Public Safety Answering Point (PSAP) in the county. When a person dials 911, it is routed to the correct PSAP regardless of telephone service or municipal boundaries. The E911 system displays telephone number and location information at the PSAP. For callers using a landline phone, the telephone number and address will be displayed automatically on the receiver’s screen. For cellular calls, the cellular telephone number and approximate GPS coordinates will display automatically. Cellular callers are more difficult to locate as the GPS coordinates are not always accurate depending upon the cellular phone and cellular carrier technology. Always be aware of your surroundings, including nearby addresses, intersections and/or landmarks.
