Codes active in the PSTN

The Pooling Administrator has been running into problems recently with NXXs where the
LERG Assignee has confirmed that the NXX has been activated in the PSTN; however the
LERG Assignee does not have trunks in place. Once the other block holders have reached their block effective dates, their blocks do not work. This leaves the PA and block holders scrambling to try to complete an expedited LERG Assignee change in order to get the numbers up and running as soon as possible.

Please be sure that when confirming that an NXX is active in the PSTN that all of your trunks are up and the code has been loaded in NPAC. This will limit the number of problems that block holders are encountering when activating their blocks from these new NXXs.

If you have any questions, please contact the Number Pooling Customer Support at 1-866-NEUPOOL or poolingsupport@Neustar.biz.
