Automatic Location Identification (ALI)

Automatic Location Identification (ALI) is an automatic display at the PSAP which shows the telephone number of the caller, as well as the location information of the origination point of the call.


How is Bandwidth Involved with ALI

The Bandwidth ALI database is the location information gateway to the country’s 9-1-1 ALI systems. Bandwidth has connectivity to regional ALI databases with every LEC ALI service provider in the country. The LEC ALI systems steer ALI queries to Bandwidth when a Bandwidth 9-1-1 enabled phone number is involved in a call to 9-1-1.

What are the Benefits of ALI

ALI steering is a function of the ALI system that enables access to the Bandwidth ALI system to retrieve dynamic location information. These ALI tables are accessed when a PSAP issues a bid for ALI display. A query received from a PSAP by the LEC ALI that contains a Bandwidth emergency service query key(ESQK) will cause a query to be sent to Bandwidth’s ALI system for retrieval of the caller’s information.
