Question

How long has 911 been able locate land line calls.?

Answer 1

In over 98% of locations in the United States and Canada, dialing "911" from any telephone will link the caller to an emergency dispatch center—called a PSAP, or Public Safety Answering Point, by the telecom industry—which can send emergency responders to the caller's location in an emergency.



In most areas (approximately 96% of the US) enhanced 911 is available, which automatically gives dispatch the caller's location, if available. Users should never be fooled into thinking that the information the 911 operator has on the caller's location or phone number is accurate. It is of paramount importance for the caller to verify their location and phone number in order to ensure help gets to the right location.
