Abstract
In a telephone network supporting local number portability, a system and method for assigning a location identifier uses a location routing number to identify the geographic location of a customer. A local carrier assigns a telephone number to a customer. The local carrier then assigns a location routing number to the telephone number. A first portion of the location routing number represents routing information and a second portion represents the location of the customer. The second portion may then be used to determine billing.
