NANPA Newsletter provides relief…
NANPA’s newsletter, always a great resource, provides a synopsis of significant area code relief activity in its second quarter 2009 issue. A brief rundown includes:
Alabama -- Planning Letter 398, for implementation of the new 938 NPA overlaying the existing 256 NPA, was published with permissive 10-digit dialing slated to begin 11/7/09 ~ mandatory 10-digit dialing will begin 6/5/10.

• Connecticut – Code conservation measures delayed the exhaust of the 203 NPA for over a decade – but implementation plans are now underway for the 475 NPA overlay. Statewide permissive 10-digit dialing started on 5/16/09 ~ with mandatory dialing beginning on 11/14/09.
• Arkansas and Pennsylvania – Relief petitions have been filed for both Arkansas and Pennsylvania, with overlay recommendations for Arkansas’ 870 NPA and Pennsylvania’s 814 and 570 NPAs.
• Kentucky – With the projected exhaust date of the 270 NPA moved to second quarter 2012 (from second quarter 2011), an order was issued delaying the start of permissive dialing for the 270/364 split to no later than 1/1/12 (from 4/1/10). The establishing of dates for mandatory dialing has been deferred.
• California – An all-service overlay has been approved as the relief method for the 760 NPA, with 442 assigned as the new NPA. Permissive seven-digit or one plus 10-digit dialing began 5/2/09 ~ and mandatory one plus 10-digit dialing will start 10/24/09.
• Illinois -- Implementation of the 312 and 773 NPAs overlay with new 872 NPA has been delayed for years by the induction of various numbering optimization measures. The NANPA newsletter provides a detailed update and indicates, "The industry should already have permissive dialing in their switches. Therefore, the industry must be prepared for a short notice to start the overlay implementation."
• Oregon – An all-services overlay for the 541 NPA was approved, with the new NPA designated as 458. Permissive seven-digit or 10-digit dialing began 7/12/09 ~ mandatory 10-digit dialing starts 1/10/10.
• Wisconsin – The approved relief method for the 715 NPA is an all-services overlay, with the 534 NPA assigned as the new code. Permissive seven-digit or 10-digit dialing begins 10/17/09 ~ with mandatory 10-digit dialing slated to begin 7/17/10.
