1 Introduction
 1.1 Purpose and Scope
 1
  1.2 Modification of the NANPA System
  1.
    
    Either the contractor, the NANC, the INC or the FCC may identify a need for change to
the NANPA system.2.
    
    All parties may discuss the needed change and address possible solutions.3.
    
    The NANC, the INC or the FCC may request the contractor to propose a solution to affect
the change. The contractor shall develop a solution and alternatives if feasible, and
associated cost of each solution. The contractor shall submit the proposal(s) and
associated cost information to the NANC for review.4.
    
    The NANC may adopt one of the proposed changes or return the proposal to the
contractor for further development/clarification.5.
    
    If and when a change to the NANPA system is adopted by the NANC or the INC, the
contractors liaison shall ensure that the proposed change is forwarded to the Contracting
Officer and the Contracting Officers Technical Representative (COTR). No change shall be
binding until such modification is issued, nor shall the Government be liable for any costs
associated with a system change until such modification is issued.

2 NOWG Recommended Scope of Work Change
   3 NeuStars Proposed Solution
  
    
    Central Office Code Availability Report (real-time report)  Pooling set-aside codes
will appear in the list of available codes.
    
    Central Office Code Utilized Report (real-time report)  Pooling set aside codes will
no longer appear on this report.
    
    Central Office Code Assignment Records (text and Excel files)  For the text files,
pooling set-aside codes will appear in the list of available codes rather than the list of
utilized codes. For the Excel files, pooling set aside codes will appear as vacant code
and available for assignment.
    
    Central Office Code Assignment Activity Record (CAA Report)  As necessary, the
quantity of pooling set aside codes will continue to appear in a separate column on the
report. However, the quantity of pooling set aside codes will be included in the total
quantity of available codes rather than the total quantity of unavailable codes. When a
pooling set-aside code is assigned, the quantity of available codes will decrease by one
and the quantity of unavailable codes will increase by one.
 4 Assumptions and Risks

Assumptions:
 
    
    NANPA will send appropriate notice via the NAS NANP Notification System (NNS) to the industry
when the changes made to these reports appear on the NANPA website.
    
    Previous Central Office Code Assignment Activity Record Reports that are posted on the NANPA
website will not be modified to reflect this change. Appropriate notation will be added to the
NANPA website to inform users of the re-classification of pooling set aside codes, the impact
on the quantity of available and unavailable codes and the effective date of the change.
 Risks:
 
    
    There may be some initial confusion when these reports are modified. Specifically, on the
CAA Report, for NPAs that have pooling set aside codes, the quantity of available codes will
increase by the number of pooling set aside codes. Some users of these reports may attempt to
compare the revised CAA Report with previous reports and notice the increase in the quantity
of available codes. This may result in questions directed to the NANPA and/or the state
regulatory authorities.
