1、1 ATIS-0300115 555 NXX Line Number Reference Document October 5, 2016 2 As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings together the top global ICT companies to advance the industrys most pressing business prioritie

2、s. ATIS nearly 200 member companies are currently working to address the All-IP transition, 5G, network functions virtualization, big data analytics, cloud services, device solutions, emergency services, M2M, cyber security, network evolution, quality of service, billing support, operations, and muc

3、h more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions, and interoperability testing. ATIS is accredited by the American National Standards Institute (

4、ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and major U.S. contributor to the International Telecommunication Union (ITU), as well as a member of the Inter-Amer

5、ican Telecommunication Commission (CITEL). For more information, visit www.atis.org.

6、on that the number(s) was not in service but stated a desire to retain them; and Assignee voluntarily returned the resource. With this information, from early 2015 through April 2016, NANPA attempted to contact all 555 line number assignees to determine if any of the numbers were in service. 8 5.0 S

7、unset of 555 NXX Assignment Guidelines Based upon the feedback received when inquiring about the 555 assignments for which a Part C had been submitted, NANPA submitted INC Issue 788 (555 Line Number Assignments and Reclamation) in January 2015. This Issue proposed revising the 555 NXX Assignment Gui

8、delines to require the assignee demonstrate it has appropriate technical arrangements in place to permit the resource to be implemented and calls to be routed. Further, NANPA also introduced the idea that the industry 1) consider having this resource returned to the inventory of NANP resources and 2

9、) prohibiting the assignment of 555 line numbers until appropriate technical arrangements were available to put the number in service. In conjunction with this effort, INC Issue 794 (Update 555 NXX Assignment Guidelines to Reflect a Moratorium on New Assignments) was accepted and resolved, resulting

10、 in a moratorium on 555 line number assignments, effective June 17, 2015 (NANPA Contract FCC 12C0023 Amendment/Modification M006). NANPA published Planning Letter 483 (Moratorium on 555 Line Number Assignments and Requirement to Provide Information on Current 555 Assignments Attachment 3) on June 19

11、, 2015, announcing the moratorium and requesting all 555 line number assignees who stated their number was in service and thus dialable on the PSTN to provide NANPA the following information: The date the resource was placed in service, The area code(s) in which calls to the 555 number can be succes

12、sfully completed, and The service provider(s) network within which the 555 line number is working. As part of its efforts to distribute PL-483 to as many 555 line number assignees as possible, the planning letter was posted on the NANPA website and email notification was sent via the NANP Administra

13、tion System (NAS) NANP Notification System (NNS). In addition, the content of PL-483 was included in the 2Q15, 3Q15, and 4Q15 NANPA Newsletters. Understanding that a large majority of 555 line numbers were assigned to individuals that may not be included in these distribution channels, NANPA also re

14、ached out via phone, facsimile, email (where available), FedEx, and U.S. mail to 555 assignees. NANPAs outreach efforts resulted in nearly 8,000 555 line numbers being returned or reclaimed in 2015 and 2016.3 This included all 555 line numbers assigned to Canadian entities/individuals, where the Can

15、adian Number Administrator conducted a similar 555 outreach program. 3 All 555 line numbers reclaimed by NANPA were reviewed and approved by the FCCs Wireline Competition Bureau. 9 Below is a summary of the status of the 555 line number resource as of July 28, 2016 Table 5.1: Status of 555 Line Numb

Unassig

18、ned 555 line numbers, including 555 numbers in dispute and excluding 100 line numbers reserved for use by the entertainment/advertising industries, were returned to the inventory of NANP resources. The future of a 555 resource will be determined if a need for the resource has been identified and agr

19、eed to by INC, and INC creates a new set of industry guidelines for the assignment and administration of the resource. 6.0 Remaining Use of 555 Numbers With the sunset of the 555 NXX Assignment Guidelines, a block of one hundred (100) 555 line numbers will remain reserved as fictitious, non-working

20、numbers for use by the entertainment and advertising industries. These specific numbers are 555-01XX, i.e., numbers between and including 555-0100 and 555-0199. The use of 555-1212 for directory assistance (National Assignment) is still permitted. The use of 555-4334 (National Assignment) is still p

25、ORKSHOP ASSIGNED: 555-NXX CURRENT STATUS: Resolved RESOLUTION DATE: 4/29/93 * 1. ISSUE STATEMENT: 555-XXXX line numbers, currently assigned by local exchange carriers, are one of the few remaining seven-digit resources that could be used on a nationwide basis. As an example, nationwide use of these

26、numbers has been proposed as an alternative resource for information service providers. (See attached correspondence.) The purpose of this issue is to stimulate discussion at ICCF to determine the industrys interest in pursuing extended use of 555-XXXX line numbers and to initiate appropriate action

27、. NANPA actively supports the expanded use of 555-XXXX. *2. SUGGESTED RESOLUTION OR OUTPUT/SERVICE DESIRED: A phased approach is suggested: First, ICCF would discuss and reach consensus on the desirability of expanded use of 555-XXXX numbers. Second, if the results from the first phase are positive,

28、 the service(s) for which these numbers would be used must be defined. (Liaison with the IILO may be required if these services involve information service providers.) Questions to be answered include whether the service(s) are to be provided locally, regionally, nationally, or all of these. Third,

29、appropriate assignment guidelines for these numbers must be developed. * 3. OTHER IMPACTS (if any): IILC Issue #036 addresses abbreviated dialing for information service providers. The FCC has an open proceeding on the use of N11 codes. U S WEST has a request from an information service provider for

30、 a 555-XXXX line number. 4. CURRENT ACTIVITY: A Workshop was formed on 12/14/92 to address this Issue. Co-Chairs are Kelly Daniels, Telco Planning, and Jim Deak, NANPA. The Workshop reported on their current activities at ICCF28. A liaison letter will be sent by the ICCF Moderator to the appropriate

31、 organizations (e.g. IILC, CompTel, Telocator, USTA, CTIA, OPASTCO) to further encourage their participation in the Workshop. At ICCF29 the Workshop indicated that the target date for completion of 555 NXX Assignment Guidelines is ICCF30. At ICCF3O, the Workshop indicated that, although it is close

32、to completing the Guidelines, a sanity check of them and of the associated Request form is still in progress. This Issue was referred to the INC Standing Committee at ICCF3O. UPDATED: 4/29/94* To be filled in by Originator 12 INDUSTRY NUMBERING COMMITTEE (INC) ISSUE IDENTIFICATION FORM ISSUE TITLE:

34、CURRENT STATUS: Resolved RESOLUTION DATE: 4. CURRENT ACTIVITY (cont): This Issue was accepted for initial closure at INC3. At INC4, Workshop participants reviewed and modified industry contributions to the guidelines and requested time at INC5 to complete its work and bring the guidelines to final c

35、losure. At INC5, the Workshop completed development of the 555 Assignment Guidelines, which will be presented for final closure at INC6 (4/29). The Guidelines Transition Plan will be reviewed for consideration of grandfathering of prior 555 assignment requests at INC6. 5. RESOLUTION: At INC6, the “5

36、55 NXX Assignment Guidelines” were accepted for final closure (INC Document INC 94-0429-002). The guidelines address the need for and use of 555 number resources including national/non-national numbers, centralized administration and service descriptions. A transition timeline was also adopted for i

37、mplementing the guidelines as follows: (1) North American Numbering Plan administration (NANPA) will prepare and distribute an Information Letter (IL) describing the guidelines and transition timeline. In addition to NANPAs normal distribution list, the IL will also be distributed to the following o

38、rganizations: Information Industry Liaison Committee (IILC), North American Telecommunications Association (NATA), National Association of Interactive Services (NAIS), Information Industry Association (IIA), Motion Picture Association, Screen Writers Guild and other entertainment/advertising industr

39、y organizations, as appropriate. The IL will be distributed by NANPA no later than May 13, 1994. (2) Requests for grandfathering of current uses of 555 numbers, except 555-1212 as described below, will be accepted by the administrator upon distribution of the IL by NANPA. Requests must be submitted

40、using the 555 NXX Assignment Request form, with a cover letter noting that it is a “grandfather” request for a 555 number. Upon request, the NANPA will make available the list of grandfathered numbers after June 17, 1994. (3) The deadline for accepting requests for grandfathering of existing numbers

41、 will expire on June 17, 1994, at which time a three-week open enrollment for 555 numbers will begin. During the open enrollment period, applications will be accepted but no assignments will be made. 13 INDUSTRY NUMBERING COMMITTEE (INC) ISSUE IDENTIFICATION FORM ISSUE TITLE: Assignment of 555-XXXX

43、d RESOLUTION DATE: 5. RESOLUTION (cont): (4) On July 8, 1994, the open enrollment for 555 numbers will expire and 555 numbers will be assigned. If multiple requests for the same number are received, the parties will be asked if they are willing to abide by a random selection process. If all parties

44、requesting the same number dont agree, a 60-day period will begin in which the administrator will communicate with all parties encouraging that they reach agreement on assignment and informing them that at the end of 60 days the issue will be referred to the appropriate regulatory bodies, if necessa

45、ry. This 60-day period can be extended if involved parties are making progress and all parties agree that additional time to reach agreement is needed. An arbitration or mediation process initiated by the parties might take place during the 60-day period if agreed to by all parties. If agreement has

46、 been reached by all parties on the assignment of the number, the administrator will make the assignment providing all but one request are withdrawn. Furthermore, any number requests involved in this process are to be counted as part of the five 555 numbers an entity may apply for. (5) All applicati

47、ons for 555 numbers received after July 8, 1994 will be treated in accordance with the Guidelines, i.e., 555 numbers will be assigned on a first-come, first-served basis with multiple requests for the same number assigned by a random selection process. 555-1212 will be considered non-assignable for

48、any purpose other than directory assistance service as provided by interexchange carriers and local exchange carriers. Existing 555 numbers will be grandfathered as non-national resources, which are in active tariffed service or otherwise provided with regulatory approval. 555 number applicants must

49、 supply the following information to the 555 administrator in order to avoid future duplicate assignments: Entity that is actively using the 555 number(s) including address, telephone number and point of contact. NPAs where the 555 number(s) is/are in service. Certify that the 555 resource was placed in service. 14 Attachment 2 Grandfathered 555 Line Numbers as of June 1994, before open enrollment 555 Line Number NPA(s) in Which Line Number is Grandfathered 1000 207, 401, 413, 508, 603, 617, 802 1212 All 1
