What does "E911" stand for?

The term "E911" stands for Enhanced 911. This refers to an advanced version of the basic 911 emergency service that provides additional features to improve the effectiveness and efficiency of emergency response. One of the key enhancements is the ability to automatically locate the caller's phone number and geographic location, which speeds up the response time and increases the chances of a successful intervention.

Enhanced 911 systems are designed to provide a more accurate and comprehensive set of data to the emergency dispatchers, including not only the caller's location but also the capability to send follow-up information, such as the nature of the emergency. This valuable information helps responders reach the scene more quickly and can improve the overall outcome of emergency situations.

The other options present terms that do not accurately define the "E911" designation, as they either do not specify that it is enhanced (like Emergency 911) or incorrectly include terms that aren’t used in this context (like Electronic 911).
