NANPA Planning Letter (PL) Number 415 - Kentucky - NPA 270 NPA; 2-way Split, Creating 364 NPA - Relief Plan Cancelled

In 2007, the Kentucky Public Service Commission (KY PSC) ordered a two-way geographic split as the relief method for the 270 NPA (serving the western portion of KY).

NANPA Planning Letter (PL) Number 414 - Ontario, Canada - NPA 249 Overlay for NPA 705

PL 414 was issued as advisement of a new carrier and test number options relative to the 249 NPA overlay for NPA 705. A bit of history on this overlay -- in 10/09, the Canadian Radio-television and Telecommunications Commission (CRTC) had directed the relief for Ontario area code 705 to be provided (effective 3/19/11) through a distributed overlay of new area code 249.

The overlay timeline was identified as:

• 1/15/11 – Calls dialed with 7-digits will receive an announcement advising the number dialed must be preceded by its area code and that their call will now proceed (will be connected).
• 3/5/11 - Mandatory 10-digit dialing begins. Calls dialed with 7-digits will connect to a similar announcement as above, however, the call will not be connected; instead, the caller will be instructed to redial using the area code. This announcement will remain until replaced by "a standard network announcement" phased in mid-June ’11.

Dialing Plan for Calls Originating in NPA 705 and 249:

• Local and Extended Area Service = 10-digits (NPA-NXX-XXXX)
• Toll and Alternatively Billed = 10-digits after the appropriate prefix digit(s).

Network testing began 11/15/10 for international and domestic carriers to ensure activation of the new 249 NPA. PL 414 was issued to advise of a new carrier and test number options. A complete listing of test numbers, along with a map showing geographic areas in this northern Ontario region served are available at www.nanpa.com.

Lessons Learned

We wanted to share a learning experience that was maximized by our data team - and resulted in the development of a new screening system for our Lookup Tools.

During a recent research project for a customer, we discovered a particular
NPA/NXX needed to be assigned to a different rate center.

Now, even though this discrepancy was not an 'error' - and did not impact our
accuracy statistics that are reported for local calling - it was an opportunity to
further fine tune our research tools. And, being the data geeks that we are,
we jumped on the chance!

To make a long story short, our data team developed and set up a new monitoring tool that will help us to determine if there are possible rate center name change issues that need to be examined more closely. Data geeks thrive on this stuff!

NANPA Planning Letter (PL) Number 413 - California - NPA 510 - Relief Plan Dismissed

As a result of a September 9, 2010, California Public Utilities Commission (CPUC) decision to eliminate rationing of the 510 area code, NANPA has rescinded the jeopardy status for this NPA. PL 413 was published as a means for NANPA to "reflect the NPA relief project for the 510 NPA as dismissed".

The 341 NPA, which had previously been designated as the overlay relief method for the 510 area code, will be retained by NANPA "as the reserved future NPA for the 510 area code unless otherwise specified by CPUC". At such time that NANPA determines relief is needed for the 510 NPA, it will initiate a new project and application with the CPUC.

Exhaust Projections

NANPA recently posted their October 2010 NPA and NANP Exhaust Projections. Carrier forecast and utilization data (submitted "via the NRUF process") is considered during the exhaust analyses, as well as a series of NANP assumptions (which have been utilized in past studies).

A detailed outline of the analysis process and complete listing of assumptions utilized may be found on http://www.nanpa.com/; but, the end result is a projected exhaust date beyond the year 2040.
