Area codes 613 and 343 are call area codes in the north american Numbering Plan ( NANP ) for Ottawa and surrounding Eastern Ontario, Canada. Area code 613 is one of the 86 original union american area codes assigned in October 1947. Area code 343 was assigned to the lapp number design area in an sheathing plan activated on May 17, 2010. In 2021, the canadian Numbering Administrator approved area code 753 as an extra overlay code for the count design area to be activated on March 26, 2022 .
history [edit ]
Reading: Area codes 613 and 343 – Wikipedia
Area code 613 was originally assigned to a count plan sphere that included all of Ontario with the exception of the Golden Horseshoe, which was assigned the area code 416. The number design area has been split doubly. In 1953, the southwestern Ontario dowry of 613 was combined with the western dowry of 416 to become number plan area 519. In 1957, the huge northwestern parcel of 613 was combined with the northern assign of 519 to receive area code 705. Since 1957, 613 covers only easterly Ontario, an area extending from Brighton and Deep River eastward to Saint Regis, Quebec. Ottawa and its twin city in Quebec, Gatineau, fall on the boundary between 613 and Quebec ‘s area code 819. however, Ottawa shares a local calling area with the former city of Hull, Quebec ( nowadays part of the “ megacity ” of Gatineau ). As a result, for 46 years, a call could be completed between Ottawa and Hull with only seven digits. A exchangeable situation prevailed in the Washington metropolitan area across three jurisdictions – Washington itself and parts of Maryland and Virginia. While there are fewer than two million people in the geographic area covered by 613, the bulge of that population lives in the Ottawa area. To preserve seven-digit dial between Ottawa and Hull, an exchange code security scheme was implemented so that the like seven-digit local number could not be assigned on both sides of the National Capital Region. technically, it was only necessary that no two prefixes within the like local calling area be duplicates, but the code protection as implemented reserved the numbers across both area codes. This think of that if a 1-819 number was being used in Hull, the corresponding 1-613 phone number could not be used anywhere in eastern Ontario, even in areas a safe distance from the National Capital Region such as Brighton. similarly, if a 1-613 count was being used in Ottawa–Carleton, the equate 1-819 number could not be used anywhere in western Quebec. federal government offices in Hull duplicated their entire allotment of multiple exchanges worth of numbers available in 613 as contribution of a “ double dialability ” scheme. By the turn of the hundred, both 613 and 819 were cheeseparing to debilitation ascribable to Canada ‘s ineffective number allotment system. Every competitive local central carrier received blocks of 10,000 numbers ( corresponding to a single prefix ) in every rate center in which it planned to offer local service, no count how small. A bantam unincorporated village ( like Odessa, Ontario, with no call central agency but hush listed as a rate center ) normally received multiple 10,000-number blocks. once a number is assigned to a rate center and CLEC, it is unavailable for function elsewhere, even in cases when a rate center has more numbers than it needs. Larger municipalities have multiple rate centres and multiple competing carriers in each. For exemplify, flush though Ottawa has been a single municipality since merging with the Regional Municipality of Ottawa–Carleton in 2001, it still has 11 rate centres ( plus portions of other rate centres chiefly located beyond the city limits ) – most with very exchangeable local calling areas – which have never been amalgamated. The “ Ottawa–Hull ” exchange only covers the area that was the city of Ottawa prior to the 2001 amalgamation, plus the early suburbs of Nepean ( central separate ) and Vanier and small sections of other urban communities. Since Canada does not use phone number pool as a respite measurement, many telephone numbers of the area code remained unused. The proliferation of cell phones and pagers, peculiarly in the larger cities in the 613 area ( Ottawa, Kingston, Belleville, etc. ) merely magnified the trouble. By 2006, the only remaining unassigned exchange prefixes in the stallion 819 region were numbers which could not be assigned to the Quebec slope of the Ottawa–Hull sphere without breaking seven-digit dial between Hull and Ottawa. Ten-digit dial in 613 and 819 became mandatary on October 21, 2006. Intraprovincial calls from rate centres with no local anesthetic calling beyond a small fragment of their own area code were returning intercept messages if dialled as seven digits. Exchange security in the National Capital Region was ended, except for the “ double dialability ” scheme for government numbers on both sides of the river. [ 1 ] This site could have been avoided had some 1-613 versions of seven-digit Ottawa-Hull numbers been assigned to areas a safe outdistance from the National Capital Region years early.
Within two years, it became apparent that a new area code was necessary ascribable to the continued number allocation trouble – an issue exacerbated by the proliferation of cell phones and pagers. A geographic split was quickly ruled out. Local call companies did not want the expense and load of changing existing customers ‘ numbers, which would have required en masse reprogramming of cell phones. As a solution, overlay area codes were proposed for both 613 and 819. Area code 343, an sheathing proposed in 2007, [ 2 ] and approved by the canadian Radio-television and Telecommunications Commission on September 10, 2008, [ 3 ] was activated for the region on May 17, 2010, [ 4 ] several years earlier than originally anticipated. [ 5 ] On 10 November 2021, the canadian Numbering Administrator approved an extra overlay code for the enumeration plan area 613/343. Area code 753 has been assigned, and will be activated on March 26, 2022. [ 6 ] [ 7 ]
Carriers [edit ]
The main incumbent local exchange carrier in area code 613 is Bell Canada, but there are some five autonomous companies serving rural exchanges : the Lansdowne Rural Telephone Company, serving Lansdowne ; [ 8 ] the North Frontenac Telephone Company, serving Sharbot Lake and Parham ; [ 9 ] the North Renfrew Telephone Company, serving Beachburg, Westmeath, and the sphere outside Pembroke ; [ 10 ] the Roxborough Telephone Company, serving Moose Creek ; [ 11 ] and the Westport Telephone Company, serving Westport. [ 12 ] besides served by area code 613 and Bell Canada is Saint-Régis, Quebec. The exchange covers the Mohawk state territory of Akwesasne, which straddles the Ontario–Québec–New York border. Calls from Saint-Régis to Fort Covington, New York, are local anesthetic although they cross an external frame. [ 13 ]
In the west, Rapides-des-Joachims, Quebec, shares an exchange with the adjacent Rolphton, Ontario. [ 14 ]
