NANPA Planning Letter (PL) Number 409 - Pennsylvania - NPA 272 to Overlay NPA 570

An all services overlay was approved by the Pennsylvania Public Utility Commission (PUC) on 7/15, as the relief method for the existing 570 NPA. The new NPA, 272, and the existing 570 NPA will serve northeastern Pennsylvania (including Scranton, Williamsport and Wilkes-Barre).

The Commission provided "unique implementation interval requirements" necessitating NANPA to "provide a monthly report on the projected exhaust date of the 570 NPA based on actual carrier demand. When the PUC determines the 570 NPA is within 3-months of exhaust it will notify the industry to start customer education and permissive dialing." As a result, the implementation timeline has yet to be determined, and the only date identified is for all network preparation to be completed no later than 3/1/11.

Once the timeframe is made available, the dialing plan for 570/272 ("coincident with the introduction of mandatory 10-digit dialing") will be as follows:

• Local & Toll Calls Terminating in Overlay Home NPAs (HNPAs) … 10-Digits (NPA-NXX-XXXX)*
• Local & Toll Calls Terminating in Foreign NPA (FNPA) Outside Overlay … 1+ 10-Digits (1+ NPA-NXX-XXXX)
• Operator Services HNPA or FNPA Call … 0+ 10-Digits (0+ NPA-NXX-XXXX)

"*1+10 digit dialing for all HNPA and FNPA calls permissible at service providers discretion."

International and domestic carriers should ensure network-wide activation of the new 272 NPA. A test number for routing verification will be available 90-days prior to the new NPA effective date. NANPA will provide another planning letter once timeline dates have been established.

NANPA Planning Letter (PL) Number 408 - Kentucky - NPA 270; 2-Way Split, Creating 364 NPA - Start of Permissive Suspended

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

PL 408 advises the KY PSC ordered a suspension to the 1/1/12 permissive dialing date. Additionally, it was ordered that the commission will continue monitoring 270 NPA developments in order to determine future relief efforts (including permissive dialing implementation dates). As a result, no dates are identified for the implementation of the 270 NPA split; and, the "mandatory dialing date shall remain open until further Order by the Commission".
