555 Line Numbers
The intended use for 555 line numbers, in the format 555-XXXX, where X is any digit from 0
through 9, includes the provisioning of information services, but may grow to include a broad
range of existing and future services as well. In 2015, no new 555 line numbers were assigned.
7
Starting June 19, 2015, a moratorium on the assignment of 555 line numbers (see PL-483) was
instituted. During the year, NANPA attempted to reach the assignees of over 5,600 assignments.
As a result, nearly 5,000 555 line numbers were returned or reclaimed.
At the end of 2015, a total of 2,667 national assignments and 230 non-national line number
assignments (196 actual line numbers, assigned to one or more assignees in one or more NPAs)
were in effect. In addition, 116 line numbers remained in “dispute” status and 100 line numbers
were reserved for the entertainment/advertising industries. At year end, 6,921 555 line numbers
were unassigned.

800-855 Line Numbers
800-855 numbers are used only for the purpose of accessing public services on the Public
Switched Telephone Network (PSTN) intended for the deaf, hard of hearing or speech impaired.
No 800-855 number assignments were made in 2015. One number was returned. There were a
total of 93 800-855 line numbers assigned at the end of 2015.
NPA 456-NXX codes
The purpose of NPA 456 and its associated NXXs is to enable the routing of inbound
international calls for carrier-specific services, particular to that service provider’s network, to
and between countries served by the NANP. No new 456-NXX assignments were requested
during 2015. A total of three 456-NXXs assigned at the end of 2015.
Vertical Service Codes
Vertical Service Codes (VSCs) are customer-dialed codes in the *XX or *2XX dialing format for
touch-tone and the 11XX or 112XX dialing format for rotary phones. They are used to provide
customer access to features and services (e.g., call forwarding, automatic callback, etc.) provided
by network service providers such as local exchange carriers, interexchange carriers or
commercial mobile radio service (CMRS) providers. NANPA made no VSC assignments in
2015.
8
Automatic Number Identification “II” digits
Automatic Number Identification (ANI) Information Integers (“II”) digits are digit pairs sent with
the originating telephone number. The digit pair identifies the type of originating station; e.g.,
plain old telephone service (POTS) or hotel/motel. No ANI II digit assignments were made in
2015.
NANPA Change Orders
NANPA Change Order 2 - Moratorium on 555 Line Number Assignments - Upon completion of
NANPA’s outreach efforts to 555 line number assignees, NANPA intends to submit a proposal to
INC concerning the future of the 555 line number resource.
NANPA Change Order 3 - NAS NRUF Updates - This change order proposed modifications to
the NRUF reporting process in order to account for the FCC’s Report and Order concerning
Direct Access to Numbers by Interconnected Voice over Internet Protocol (VoIP) providers.
Also included were other general updates to the NRUF reporting forms (e.g., inclusion of
“Interconnected VoIP” as a service type on the NRUF Form 502 for both geographic and nongeographic resources for all submission methods, elimination of NAS NRUF reports in .xls
format and implementation of the ExcelTM Form 502 in an .xlsm format). Since the 502 Form is
scheduled for renewal in June 2016, it is expected this change order will be approved as part of
the renewal process.
NANPA Change Order - 4 - INC Issue 497: Identify Changes to INC Guidelines Based on
NANC’s Report and Recommendation, VoIP Service Providers’ Access Requirements for NANP
Resource Assignments (July 19, 2005), and FCC Order 15-70 (June 22, 2015) and INC Issue 797:
Updates to the INC Guidelines Forms - This change order proposed modifications to the resource
application forms found in the NANP Administration System (NAS) for Central Office Codes,
Carrier Identification Codes (CICs), the 5XX NPA and the 9YY NPA. These changes include the
following:






Updating references to the Code of Federal Regulations (CFR) that appear on the various
number resource forms.
Modifications to the iconectiv trademark for ‘CLLI’ found on various resource forms.
Removal of unnecessary CIC and ACNA fields on the CIC Part A, B, and C forms.
Addition of new instructions for interconnected VoIP service providers on the CIC Part A
application form.
Various changes to the 9YY application forms, including:
o Deletion of the option to provide certification on the Part A assignment form;
o Addition of the Months-To-Exhaust on the Part A assignment form; and
o Addition of code information confirmation to the Part B disposition form.
Reference to January 4, 2016 as the correct version date for the above resource forms.
Work is currently underway to include the above modifications on all appropriate resource
forms in NAS.

NANP Administration System (NAS) Highlights
2015 NAS Enhancements
 Upgraded the NAS application software (Oracle WebLogic) to Version 12.1.2 in May.
 NAS failover exercises conducted in May and October.
 Additional memory was added to the NAS application servers in November.
 The NANPA public website was converted from HTTP to HTTPS in December. This
modification was in response to an Office of Management and Budget (OMB) directive that
federal government websites only use secure HTTPS connections.
 NAS production operated successfully in Charlotte October 9-18, 2015. PAS also operated in
Charlotte during the same time period.
 Eight software builds were implemented in 2015. Enhancements introduced into NAS
included:
o Added an on-screen warning to remind the user that if the service provider OCN is
changed after completing worksheets but before submitting the NRUF that all of the
NRUF data will be applied to the last service provider OCN selected.
o Added error checking to identify when the service provider reports utilization or
forecast multiple times for the same resources have changed from minor to major.
o Added a specific reply message text for NRUFs submitted by email or FTP that
generate a major error.
o The “Cancel” button appearing on 26 NRUF work screens (all Geo and Non-Geo
worksheets---U1, U2, F1A, F1B…---on the Create and Modify/Delete pages) was
relabeled to a “Back” button on the NAS NRUF on-line feature.
 With this change, the “Back” button functions the same as the “Completed
Worksheet” button; that is, the data in the worksheet will be retained if the
user returns to it. Previously, when the user selected the “Cancel” button, all
the data entered on the worksheet was removed.
o Expanded the Notes/Assignee field for downloading the NRUF Utilization Report to
Excel™. With this enhancement, all of the Notes/Assignee data are located on the
same line as the applicable code or block.
o Introduced a new error check to identify when the same code or block is listed with
different rate centers on a utilization worksheet (e.g., U1, U2, etc.) when submitted
via the Excel spreadsheet or FTP.
o Revised the file name for downloaded NRUF Forecast Reports by service providers
by excluding the phrase “IncludingPA” in the Forecast Report file name (e.g.,
Forecast_IncludingPA_Report.xlsx since no Pooling Administrator forecast has ever
been part of the report. File name is now simpler and easier to read (i.e.,
Forecast_Report.xlsx).
o Introduced a number of error checks in the mass modification process to include:
 Identification of codes included on the mass modification spreadsheet that
are either not assigned to an OCN in the user’s profile or are currently
vacant;
 Identification of codes where a future event is scheduled;
 Permit multiple types of changes on the mass modification spreadsheet, and;
 Allow updating of the Parent Company OCN when submitting a mass
modification for intra-company OCN changes.
o Modified the NAS NNS functionality to require the user to provide a specified time
period of no more than 365 days when requesting All States, All NPAs and All NNS
Categories. This limitation was put in place due to the large volume of notices in
NNS.
o Password Expiry Reminder notices were enhanced to provide a link to the page on
the NANPA website which includes the NAS User Registration Guide and detailed
18
instructions for the user to update the applicable NAS password. Previously, a
specific page number in the User Registration Guide was listed in the notices
pertaining to resetting passwords which had to be periodically updated with each
revision to the User Registration Guide.
NAS Users
