Automatic Location Identification (ALI)

Automatic Location Identification (ALI) is a technology used in the context of emergency services to automatically provide the location of a caller when a 911 call is made.

This system is crucial for ensuring quick and accurate response in emergency situations. Here are some key points about ALI:

  • Location Information for Emergency Calls: When a 911 call is placed, the ALI system automatically provides the dispatcher with the caller's location information. This is particularly important if the caller is unable to communicate their location or is unaware of it.


  • ALI Database: The ALI system relies on a database that links telephone numbers to physical addresses. For landline calls, the address registered with the phone number is typically used. For mobile calls, more advanced location detection technologies are used.


  • Enhanced 911 (E911) Services: ALI is a part of Enhanced 911 services, which improve the effectiveness of 911 services, especially in the case of cell phone calls. E911 can provide more precise location information, such as GPS coordinates.


  • Critical for Emergency Response: Accurate location information provided by ALI can significantly reduce response times for police, fire, and medical emergencies, potentially saving lives.


  • Privacy Considerations: While ALI is crucial for emergency services, it also raises privacy concerns. Therefore, its use is typically restricted to emergency response scenarios.

Automatic Location Identification is an essential component of the emergency response infrastructure, playing a vital role in ensuring quick and efficient dispatch of emergency services to those in need.
