NANPA Planning Letter (PL) Number 417 - Wisconsin - NPA 274 to Overlay NPA 920

Due to changes in the 920 NPA's projected exhaust date, on 11/15/10, the Public Service Commission of Wisconsin postponed the previously approved 920-274 NPA overlay. The new 274 NPA will serve the same geographic locations currently served by the 920 area code, which generally covers the northeastern portion of Wisconsin (including Appleton, Beaver Dam, Berlin, Fond du Lac, Fort Atkinson, Green Bay, Manitowoc, Oshkosh, Ripon, Sheboygan, Sturgeon Bay and Watertown).

PL 417 communicates the new timeline for implementation as recapped below:

• 05/04/13 -- Permissive 10-Digit Dialing Starts
• 08/22/13 -- Earliest Date to Order Central Office Codes for New NPA
• 01/25/14 -- Permissive Dialing Ends / Mandatory 10-Digit Dialing Begins
• 02/22/14 -- Earliest Date for New NPA Central Office Code Activation / Effective Date for New NPA

Effective 1/25/14 (mandatory 10-digit dialing), the dialing plan for 920 and 274 NPAs will be as follows:

• Local, EAS and ECC Calls Terminating in Home NPA (HNPA) or Foreign NPA (FNPA) … 10-Digits* (NPA-NXX-XXXX)
• Toll Calls Terminating in HNPA or FNPA … 1+ 10-Digits (1+ NPA-NXX-XXXX)
• Operator Services (Credit Card, Collect, Third Party) Calls Terminating in HNPA or FNPA … 0+ 10-Digits (0+ NPA-NXX-XXXX)

*1+10 digit permissible at service provider discretion

While 10-digit dialing is encouraged during the permissive period, subscribers may use either seven- or 10-digit calling in the overlay area during this time. And, it is always good practice for carriers to prepare their switches for 10-digits well in advance of the mandatory dialing conversion date. Additionally, international and domestic carriers should ensure the new 274 NPA has been activated network-wide prior to 2/22/14. (Test numbers for routing verification to the new NPA will be in effect 11/18/13 – 3/20/14 and are: 274-274-1274 for LATA 350 and 274-222-8378 for LATA 356.)

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!
