A method for providing emergency location information to an emergency service provider is provided. The method, in one implementation, includes the steps of (a) providing a plurality of sets (e.g., ranges) of OSI Layer 3 or Network Layer addresses; (b) receiving an emergency call from a calling device having an OSI Layer 3 or Network Layer address; (c) mapping the calling address against the plurality of sets of addresses to determine an ELIN for the calling address; and (d) forwarding the ELIN to a public safety answer point. Each set of addresses comprises a plurality of addresses, and a plurality of ELINs corresponds to the plurality of sets of addresses. In each set of addresses, a corresponding one of the plurality of ELINs is typically common to a plurality of addresses.
