Part 4 Obligations

As a reminder, per section 8.3.10 of the Thousands-Block Number (NXX-X) Pooling
Administration Guidelines, “A thousands-block assigned to a 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). If the SP identifies that it will not meet the activation deadline, due to circumstance beyond its control, the SP may request an extension from the state commission.” By submitting a Part 4, the SP is certifying that the thousands-block has been entered into the LERG Routing Guide and has begun to activate and assign numbers within the thousands-block to end users (FCC 00-104, 240).
