NANPA recommends service providers and consultants to pull the NRUF Utilization Missing Report the next business day, after receiving a confirmation that the NRUF report has been accepted. The NRUF Utilization Missing Report can be found in NAS by going to the NRUF toolbar and selecting Reports. If there are any Central Office codes (NPA-NXXs) and/or Thousands-Blocks (NPA-NXX-Xs) appearing on the NRUF Utilization Missing Report, action is required. If you receive “No results found for those search parameters,” you have reported on all of your assigned numbering resources for the current reporting period.
