For example, a call originating outside of Virginia destined for a number with the 703 area code will be routed to a service provider operating within Northern Virginia.
-
Local Exchange Carrier (LEC) Assignment
Based on the area code, the call is directed to the specific LEC serving that geographic area. LECs maintain databases that map area codes and phone number prefixes (the first three digits after the area code) to their respective switching centers. These switching centers then handle the local routing of the call to the intended recipient. The accuracy of this assignment is paramount for efficient call delivery.
-
Inter-Carrier Routing Agreements
When a call originates from a different network than the destination number, inter-carrier routing agreements become essential. These agreements define how different telecommunication providers exchange traffic and ensure that calls are routed correctly across network boundaries. The area code dictates the initial routing decision, which then triggers the appropriate inter-carrier agreements. Without these agreements, calls could be misdirected or fail to complete.
