Reclamation Procedures

Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Reclamation Process

Per Section 11 of the ATIS-0300119, Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines (TBCOCAG), all service providers must certify that CO codes and thousands-blocks have been entered into the LERG™ Routing Guide (LERG) and have begun to activate and assign numbers to end users (FCC 00-104, ¶240).

If NANPA does not receive the Confirmation of Thousands-Block (NPA-NXX-X) or Central Office (CO) Code (NPA-NXX) In Service – Part 4, during the first five months following the original effective date issued on the Part 3, NANPA will send a Part 4 Reminder Notice to the CO Code and/or thousands-block holder. The notice will instruct the CO Code and/or thousands-block holder to submit a Part 4 by the Part 4 due date or be subject to having the CO Code and/or thousands-block reclaimed. Part 4 status may also be reviewed in NAS.

If the CO Code and/or thousands-block was not placed in service within six months of the original effective date returned on the Part 3, the assignee may apply to the appropriate State regulatory authority or FCC point of contact for an extension. A list of appropriate State regulatory contacts and the FCC point of contact for those state commissions who decline to exercise their authority can be found here.

The NANPA cannot accept delinquent Part 4s for CO Codes and/or thousands-blocks without regulatory approval.
