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 inconectiv'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." For more detail on selecting or changing an AOCN, click here. A list of companies that provide AOCN services is on the Telecom Routing Administration (TRA) web site.

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