Which communication system can automatically identify a caller's phone number and location during an emergency?

The Enhanced 911 system is designed to automatically identify a caller's phone number and location during an emergency. This capability is crucial for emergency responders to quickly locate individuals in need of assistance, especially when the caller may be unable to communicate their situation effectively due to an emergency event.

Unlike the Basic 911 system, which only transmits the phone number without additional location information, the Enhanced 911 system provides comprehensive details, such as the exact address, which significantly speeds up response times. This advanced system also includes features such as the ability to track location for mobile callers, making it invaluable in situations where individuals might call from various locations without being able to relay their information clearly.

Other options, such as Direct Line Service and Emergency Contact System, do not possess the automatic features that identify a caller's location and phone number, which is why they are not suitable answers to this question.
