The NANPA and the Pooling Administrator shall consult with the Wireline Competition Bureau prior to exercising the authority delegated to it in this provision.
(j)Sequential number assignment.
(1) All service providers shall assign all available telephone numbers within an opened thousands-block before assigning telephone numbers from an uncontaminated thousands-block, unless the available numbers in the opened thousands-block are not sufficient to meet a specific customer request. This requirement shall apply to a service provider's existing numbering resources as well as any new numbering resources it obtains in the future.
(2) A service provider that opens an uncontaminated thousands-block prior to assigning all available telephone numbers within an opened thousands-block should be prepared to demonstrate to the state commission:
(i) A genuine request from a customer detailing the specific need for telephone numbers; and
(3) Upon a finding by a state commission that a service provider inappropriately assigned telephone numbers from an uncontaminated thousands-block, the NANPA or the Pooling Administrator shall suspend assignment or allocation of any additional numbering resources to that service provider in the applicable NPA until the service provider demonstrates that it does not have sufficient numbering resources to meet a specific customer request.
(1) All telecommunications service providers shall be subject to “for cause” and random audits to verify carrier compliance with Commission regulations and applicable industry guidelines relating to numbering administration.
(2) The Enforcement Bureau will oversee the conduct and scope of all numbering audits conducted under the Commission's jurisdiction, and determine the audit procedures necessary to perform the audit.
