Rating and Routing Data Entry (AOCN)


Once a central office code (NXX) or a thousand-block (NXX-X) has been assigned, it is the responsibility of the service provider to ensure that the data included in the Part 2 of the central office code application and the Part2A of the thousands-block application be entered into the iconectiv's Business Integrated Routing & Rating Database System (BIRRDS). The Part 2 forms are located at

The service provider may enter its own data or may have another company to do it. Each company that provides this data entry service has an assigned Administrative Operating Company Number (AOCN). Selecting a company to provide the service is referred to as "selecting an AOCN." A list of companies that provide AOCN services is located at the iconectiv TruOps Telecom Routing Administration (TRA).

NANPA is required to provide AOCN services. For more information about NANPA's AOCN service and fees, please contact the AOCN administrator at
