New Saskatchewan area code 639

On September 7, 2012 NANPA announced the introduction of a new area code for the Canadian province of Saskatchewan starting May 25, 2013. The new 639 area code will overlay existing area code 306 currently serving the aforementioned province (Saskatoon, Regina, Yorkton, …).

Starting February 25, 2013 carriers in the 306 area will be able to play a network announcement notifying callers dialing just the local 7 digit number that the call they have dialed must now be preceded by a 3 digit area code. However, these calls will still be completed without adding the area code until May 25 when 10 digit dialing becomes mandatory.

Starting May 25, 2013 all calls in the newly created 306/639 overlay complex dialed with just 7 digits will be preceded by a network announcement informing the caller that they must hang up and dial the call using 10 digit dialing.

New 566 PCS area code

On April 17, 2012 NANPA added the new 566 NPA to the North American Numbering Plan. The code is assigned for Personal Communications Services along with NPAs 500, 533 and 544.

PCS codes are non geographic Service Access Codes used for so called Personal Communications. Basically, when calling a phone number starting with area code 566 (or 500, 533 and 544) your call is redirected to a real geographic phone number. PCS numbers are generally used by people or businesses who need to highly customize how their telephone system works. Calls can be redirected to national or sometimes international locations, often a message is played for callers of a PCS number (such as Press 1 for English and 2 for Spanish). PCS numbers can also be programmed to ring to certain phone numbers depending on the time when the call is placed (for example they can ring to a business phone during regular business hours and forward to a voicemail afterwards).

New California area code 669

The California Public Utilities Commission approved on October 20, 2011 the introduction of an overlay area code as a relief plan for existing NPA 408 serving cities such as Santa Clara, Cupertino, San Jose, Sunnyvale. The new area code 669 will cover the exact same area currently covered by area code 408. As a result 1+10 digit dialing will be the dialing format for residents of this area. Permissive 1+10 digit dialing in area code 408 will commence on April 21, 2012 and end on October 20, 2012 when 1+10 digit dialing becomes mandatory. The new area code 669 will officially be activated on November 20, 2012.

New Manitoba area code 431

The Canadian province of Manitoba will have a new area code starting November 3, 2012. The new area code 431 will overlay NPA 204 currently covering the whole province of Manitoba with cities such as Winnipeg, Steinbach, Thompson, Winkler. Starting July 29, 2012 carriers operating in this area can choose to precede all calls with an announcement notifying callers that local calls should be dialed using the 10 digit format. 10 digit dialing will become mandatory on November 3.

New Quebec area code 873

A new area code was recently announced for the Western Quebec communities of Drummondville, Gatineau, Sherbrooke, Trois-Rivieres and more. The new area code 873 will become active on September 15, 2012 and will cover the same geographic area currently served by area code 819. With the introduction of the new 873/819 overlay complex this area will use 10 digit dialing for local calls. I couldn’t find any details in the official announcement regarding a permissive 7/10 digit dialing period (a 3 month or more permissive period is generally used before an overlay area code is introduced; this way people can get used to dialing 10 digits instead of 7).

New Maryland area code 667

A new area code 667 will be activated on March 24, 2012 for the eastern part of Maryland currently served by area codes 410 and overlay area code 443 and covering cities such as Aberdeen, Baltimore, Ellicott City, Dundalk. The introduction of the new code was decided back in 2001. Since this part of Maryland has 2 area codes already and therefore 10 digit dialing has been mandatory since the introduction of area code 443 in 1997, no permissive 10 digit dialing will be needed.

Sint Maarten new NANP area code 721

Sint Maarten is a Caribbean territory known as a Constituent Country of the Kingdom of the Netherlands. Sint Maarten along with 5 more islands (Aruba, Bonaire, Curacao, Saba and Sint Eustatius) used to constitute the Netherlands Antilles until October 2010 when the country was disolved. The southern part of Sint Maarten island (also known as Saint Martin) now uses the North American Numbering Plan and has been assigned area code 721 introduced on September 30, 2011. Before the aforementioned date Sint Maarten had used country code 599 which remains in service for Bonaire, Curacao, Saba and Sint Eustatius. The old and new numbering systems will run in parallel for a year (people using country code 599 to dial to Sint Maarten will hear a message announcing the new area code).

Note that the northern part of the island, known as Saint Martin is a French Overseas Collectivity and uses country code 590.

A new area code was announced on June 21, 2011 for the US state of North Carolina. The new area code 984 will overlay (cover the same area) existing NPA 919 starting April 30, 2012.

The 10 digit permissive dialing period will begin on October 1, 2011 and end on March 31, 2012. During this period, local calls in area code 919 can be dialed in both 7 and 10 digit dialing formats.

New NYC area code 929

A 4th area code will be introduced on April 16, 2011 to cover the Bronx/Brooklyn/Queens/Staten Island area of New York City. The new area code 929 will be added to the existing area codes 347, 718 and 917 currently covering this area. There is no need for a permissive 10 digit dialing period since this part of New York City has long had 10 digit mandatory dialing.
