ELIN (Emergency Location Identification Number)

An Emergency Location Identification Number (ELIN) is a ten digit DID number you purchase from the local exchange carrier (LEC), and is one way for organizations to provide specific location information to the public safety answering point (PSAP) for a 911 call. During a 911 call, the ELIN takes the place of the caller’s telephone number as the ANI and is used to route the call to the appropriate PSAP. The PSAP uses the ELIN to query the automatic location identification (ALI) database and retrieve the caller’s location.
