INC Report to the NANC 6 Issue 775: Edits to COCAG Appendix C Section 5.8 – Pooled NXX return when Code Holder retaining ports Issue 740 allows a code holder with ported TNs but no assigned blocks to submit a request for a pooled central office code return to the PA when there are blocks assigned to other service providers. At the March INC meeting, the PA provided statistics showing an increase in code returns. Asking service providers with only ported TNs to become the code holder resulted in: extra work for the PA very few, if any, volunteers among those service providers a delay to the disposition of the application Under Issue 775, INC eliminated the step for the PA to contact the service providers with only ported TNs, thus streamlining the work for the PA and service providers and providing the disposition of the code return request sooner. Going forward, the PA will only contact the block holders.

INC Report to the NANC 7 Issue 778: Update INC Guidelines to Identify Permitted Company Code (OCN) Category Types Appropriate for Assignment of Numbering Resources Service providers (SPs) entering into the telecom/VoIP industry require a NECA assigned Company Code (OCN) in order to receive numbering resources from NANPA or Pooling Administration. The OCN must be assigned to a NECA Company Code category type that is permissible to receive numbering resources, however, the list of permissible categories has never been clearly defined in INC guidelines, resulting in: SPs with an incorrect Company Code category type attempting to request numbering resources SPs changing the Company Code category type of their OCN after numbering resources have been assigned to it INC will list the permissible Company Code category types in the guidelines to support existing NANPA and PA processes to deny requests when an inappropriate NECA Company Code category type is used. INC will ask NECA to update its website and documentation to help new entrants determine the appropriate Company Code category type.
