Examples of the invention are used to provide a system and method
for provisioning a telematics unit number based on a phone number
already used by a customer. In examples, the telematics unit is
provisioned with a number that aligns with a rate center plan, which
is likely to result in a number that is local to a number the customer
uses for dialing the unit and/or matches the area code of a number on
the customer's account. In example a wireless telephone number is
assigned to a vehicle telematics unit from an inventory of available
wireless telephone numbers by querying the inventory to identify the
wireless telephone number that matches one or more of the customer's
home rate center, customer's NPA, customer's NXX, and customer's
overlay NPA information based on a plurality of predetermined
conditions.
