Part 4 Obligations
As a reminder, there is no need to wait until you receive a Part 4 Reminder Notice to submit
your Thousands-Block Application Form Part 4. You may submit a Thousands-Block
Application Form Part 4 as soon as you’ve placed the NPA-NXX-X in service (A code or block for which local routing information has been input to the LERG Routing Guide and the carrier has begun to activate and assign numbers within the NXX code or NXX-X block to end users (FCC 00-104, ¶240).)
Per section 8.3.10 of the Thousands-Block Number (NXX-X) Pooling Administration Guidelines (TBPAG), “A thousands-block assigned to an SP should be placed in service by the applicable activation deadline, that is, six months after the original effective date returned on the Part 3 and entered on the BCD/BCR screen in BIRRDS. Confirmation that the block has been placed in service is mandatory. If the PA does not receive the Part 4 – Confirmation of NXX-X Block In Service, the PA will start the reclamation process within 60 calendar days of the expiration of the applicable activation deadline by referring instances of unactivated thousands-blocks to the relevant state commission (see Section 9.1.3) [1]. If the SP identifies that it will not meet the activation deadline, due to circumstances beyond its control, the SP may request an extension from the state commission.”
