Enhanced 9-1-1 (E9-1-1) Glossary of Commonly Used Terms

Enhanced 9-1-1 or E9-1-1 service is a North American telephone network (NANP) feature of the 9-1-1 emergency-calling system that automatically associates a physical address with the calling party’s telephone number as required by the Wireless Communications and Public Safety Act of 1999. This is generally done by a form of reverse telephone directory that is supplied by the telephone company as a computer file, used to associate the caller’s phone number with a physical street address. It provides emergency responders with the location of the emergency without the person calling for help having to provide it. This is often useful in times of fires, break-ins, kidnapping, and other events where communicating one’s location is difficult or impossible.
