1. National Thousands Block Number Pooling Services NANC Meeting January 13, 2004

2. 2 Implementation Update As of December 12, 2003, pooling was implemented in all area codes in the national rollout schedule [except Alaska]. On December 19, 2003, the FCC advised the Pooling Administrator (PA) to update the list of Top 100 Metropolitan Statistical Areas (MSAs) to correspond to the MSA information provided by the Office of Management and Budget in OMB Bulletin 03-04 and its supporting documentation. The PA has completed the updates to the list of Top 100 MSAs, and has added new ones to the existing list. No MSAs were removed from the list, even if they changed from a previous Top 100 designation to non Top-100.

3. 3 Implementation Update Continued Approximately 1,100 additional rate centers will now be included as either mandatory (M) or single service provider (M*) rate centers. Implementation meetings to develop milestone dates for each affected area code will be completed by April 1. More than one area code may be included in a meeting. The implementation meeting process will be similar to that of the national rollout.
