    Description
    Currently there is no direction in ATIS-0300119, Thousands-Block
    (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines
    Section 9.2 regarding effective date changes to Pooled CO Codes.

    NANPA suggests adding language to ATIS-0300119, Thousands-Block (NPA-NXX-X)
    & Central Office Code (NPA-NXX) Administration Guidelines regarding
    effective date changes to Pooled CO Codes. NANPA suggests adding the
    following to a new Section 9.2.8:
    • an effective date change may be modified to an earlier effective date,
    • an effective date change may be modified to a later effective date when
    there are no Thousands-Blocks assigned to SPs other than the Code Holder
    • an effective date change shall be denied when there are Thousands-Blocks
    assigned to SPs other than the Code Holder

    Each item would indicate the impacts on the Part 4 Due Date, Available Date
    of Thousands-Blocks in the Industry Inventory Pool, and direction on how to
    update the Thousands-Block Holders when an effective date change is denied.
