• INC: Industry Numbering Committee
  • Issue: 0961
  • Title: INC Issue 0961 Update TBCOCAG To Require NANPA/PA To Obtain NPAC Reports Each Business Day
  • Statement: Today NANPA submits a request for an ad hoc report from the NPAC to determine contamination and the presence of LRNs when 1) thousands-blocks or CO codes are returned or abandoned, or 2) thousands-blocks available in the pool are identified as being over-contaminated (greater than 10%). The NANPA has been authorized to obtain these ad hoc NPAC reports once a week under permission previously granted by the North American Portability Management LLC (NAPM LLC). The NPAC ad hoc reports contains the following data: 1) the total quantity of ported numbers within the thousands-block or CO code, 2) the total quantity of ported numbers within the thousands-block or CO code subtotaled by Service Provider ID (SPID), and 3) the quantity of Location Routing Numbers (LRNs) contained within the thousands-block or CO code. The volume of situations where NANPA needs to request these ad hoc reports appears to be growing. If NANPA were permitted to request these ad hoc reports each business day (as needed), rather than just once a week, it would simplify NANPA'ss processes, allow for more timely processing of thousands-block and CO code returns, and potentially add eligible thousands-blocks to the pool more quickly.
  • Resolution: INC agreed to update ATIS-0300119, Thousands-Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines (TBCOCAG) To Require NANPA/PA To Obtain NPAC Reports within five calendar days, as shown in INC-2024-00088R001. The NANPA shall send the request to the NPAC on Tuesdays and Thursdays as jointly agreed to by ATIS INC, NPIF (Number Portability Industry Forum), and the NAPM LLC. The resolution of this Issue will generate a NANPA Change Order. This Issue will remain in Initial Pending status until the approval and implementation of the Change Order.
  • Status: Final Closure

  • Issue: 0995
  • Title: NPA Allocation Plan and Assignment Guidelines to align NPA Assignment for all existing NANP countries
  • Statement: The Canadian Numbering Administrator (CNA) notified NANPA of the need for additional Numbering Plan Area (NPA) codes. Staff from the North American Numbering Plan Administrator (NANPA), Canadian Numbering Administrator (CAN), and Canadian Radio-Television and Telecommunications Commission (CRTC) discussed the options of setting aside reserved codes for future Canadian Geographic and Non-Geographic use or electing to follow the US process outlined in ATIS-0300055, NPA Allocation Plan and Assignment Guidelines. At the October 2024 Canadian Steering Committee on Numbering (CSCN) plenary meeting the industry agreed to forego negotiating a set reservation pool as Canada had done previously and elected to use the US procedures outlined in ATIS-0300055, NPA Allocation Plan and Assignment Guidelines. The CSCN Secretary General sent a recommendation letter to the CRTC on November 14, 2024, outline this plan.
  • Resolution: ATIS INC updated ATIS-0300055, NPA Allocation Plan and Assignment Guidelines to align NPA Reservation for all existing NANP countries to add language for reserving/releasing NPAs by non-NANPA managed countries (e.g., Canada).
  • Status: Final Closure

  • Issue: 0996
  • Title: Notifications from NPAC in TBCOCAG and Part 1B Form & Part 5 Form
  • Statement: The language in sections 11.1.11.7 & 13.1.1 of the TBCOCAG and section C of Parts 1B Form & Part 5 Form does not reflect the actual notification process and could cause confusion for Thousands-Block Holders expecting to be contacted directly by the NPAC when their Thousands-Block has been Activated/Modified/Ported (Part 1B) or Reclaimed (Part 5).
  • Resolution: ATIS INC agreed to modify sections 11.1.11.7 & 13.1.1 of the ATIS-0300119 Thousands Block (NPA-NXX-X) & Central Office Code (NPA-NXX) Administration Guidelines (TBCOCAG), Part 1B Form & Part 5 Form to correct the NPAC notifications as identified in the associated contribution to reflect current processes.
  • Status: Final Closure

• NRSC: Network Reliability Steering Committee
  • Issue: 0057
  • Title: 988 Lifeline Designated Points of Contact
  • Statement: FCC 23-57 WC Docket No. 18-336 establishes a requirement to deliver notifications to 988 special facility Designated Point of Contact (DPOC). This contact information must exercise “special diligence” to identify, maintain, and, on an annual basis, confirm current contact information. Three 988 special facilities must be contacted, SAMHSA, the VA, and the 988 Lifeline Administrator. However, the Commission does not provide material guidance on establishing these initial DPOCs, leaving each service provider to search out contact, email, and phone individually. This issue would leverage the NRSC membership to work together on identifying these DPOCs for industry use.
  • Resolution: The NRSC leadership met several times between August 2024 and March 2025 with the 988 stakeholders and obtained phone numbers, email addresses, and names for 988 outage reporting. This information was subsequently shared with the NRSC membership.
  • Status: Initial Closure

• WTSC: Wireless Technologies and Systems Committee
  • Issue: 0106
  • Title: Transfer of OMA Location Working Group MLS/MLP, SUPL, and LPPe Enablers to WTSC
  • Statement: Due to changes in the industry, OMA BoD is changing focus away from maintenance of Enablers developed in the OMA Loc WG. As a result, there is a need to move the MLS/MLP, SUPL, and LPPe Enabler Specifications to an SDO that can provide the leadership and participation necessary to maintain and evolve these Enablers for the foreseeable future.
  • Resolution: This Issue was closed with the publication of the following ATIS transpositions, available in the WTSC Publications folder
  • Status: Initial Pending

  • Issue: 0102
  • Title: Lawful interception for Voice Services in the VPLMN with home-routed roaming
  • Statement: WTSC-LI previously developed and published a standard ATIS-0700005 titled Lawfully Authorized Electronic Surveillance for 3GPP IMS-based VoIP and other Multimedia Services. When that standard was developed home-routed roaming scenarios were not considered, and accordingly, the focus was only on Local Breakout (LBO) as the roaming architecture. Since then, home-routed roaming is now determined to be the preferred approach over LBO, and 3GPP SA3 LI has developed the stage 2 and stage 3 details to support LI in the VPLMN for home-routed roaming architecture. Updates to the ATIS LI Standards would provide the benefit of clarifying the application of the LI in the VPLMN with home-routed roaming to the US LI requirements per CALEA.
  • Resolution: Issue 0102 was placed into Initial Closure with participant consensus that analysis indicates that 3GPP LI standards (TS. 33.127 and TS. 33.128) must be used, and no changes are required for North American standards.
  • Status: Final Closure
