Reissued with the resolution of Issue 767..

This document specifies guidelines for the administration and assignment of thousands-blocks (NXX-Xs) to Local Number Portability (LNP)-capable service providers (SPs) in rate centers where thousands-block number pooling has been ordered or implemented. All thousands-block requests and necessary forms will be submitted by SPs to the Pooling Administrator (PA) by filling out the appropriate request and/or form provided on the PA Web Site. No requests and/or form submissions will be accepted via fax, paper, voice, or e-mail, except in extraordinary circumstances, semi-annual Appendix 1, and/or if previously agreed to by the PA. An industry database will verify the password and access level of the user. All electronic submissions from an authorized user will be considered as an electronic signature and will be verified for authenticity utilizing criteria maintained in the PA database. In addition, these guidelines outline the processes used between the PA and: Code Holders, Telcordia™ LERG™ Routing Guide Assignees, Block Holders, The CO Code Administrator, Number Portability Administration Centers (NPAC), North American Numbering Plan Administrator (NANPA), and Regulatory Agencies.
