Area codes 613 and 343

Area code 613 and overlay area code 343 are area codes for Ottawa and surrounding Eastern Ontario, Canada, in the North American Numbering Plan (NANP). 613 is one of the 86 original area codes in the NANP assigned in October 1947.

History

Ottawa, Ontario

The 613 area originally covered all of Ontario with the exception of the Golden Horseshoe, which was in area code 416. The area code has been split twice. In 1953, the Southwestern Ontario portion of 613 was combined with the western portion of 416 to become 519. In 1957 the vast northwestern portion of 613 was combined with the northern portion of 519 to become area code 705. Since 1957, 613 covers only Eastern Ontario, an area extending from Brighton and Deep River eastward to Saint Regis, Quebec.

Ottawa and its twin city in Quebec, Hull fall on the boundary between 613 and Quebec's area code 819. However, they share the same local calling area. As a result, local calls could be completed between Ottawa and Hull with only seven digits. A similar 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 bulk of that population lives in the Ottawa area. To preserve seven-digit dialling between Ottawa and Hull, an exchange code protection scheme was implemented so that the same 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 same local calling area be duplicates, but the code protection as implemented reserved the numbers across an entire area code. This meant that if a 1-819 number was being used in Hull, the corresponding 1-613 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 number was being used in Ottawa-Carleton, the corresponding 1-819 number could not be used anywhere in western Quebec. Federal government offices in Hull duplicated their entire allocation of multiple exchanges worth of numbers available in 613 as part of a "dual dialability" scheme.

By the turn of the century, both 613 and 819 were close to exhaustion due to Canada's inefficient number allocation system. Every competitive local exchange carrier received blocks of 10,000 numbers in every rate centre in which it planned to offer local service, no matter how small. A tiny unincorporated village (like Odessa, Ontario, with no telephone central office but still listed as a rate centre) usually received multiple 10,000 number blocks. Larger municipalities have multiple rate centres and multiple competing carriers in each. Ottawa, now one municipality, has 11 rate centres (plus portions of other rate centres primarily located beyond the city limits) - most with very similar local calling areas - which were never amalgamated. The "Ottawa-Hull" exchange only covers the area that was the city of Ottawa prior to the 2001 amalgamation, plus the former suburbs of Nepean (central part) and Vanier and small sections of other urban communities. Once a number is assigned to a rate centre and CLEC, it is unavailable for use elsewhere, even in cases when a rate centre has more numbers than it needs.

These factors resulted in thousands of wasted numbers, and the proliferation of cell phones and pagers only magnified the problem. By 2006, the only remaining unassigned exchange prefixes in the entire 819 region were numbers which could not be assigned to the Quebec side of the Ottawa-Hull area without breaking seven-digit dialling between Hull and Ottawa.

Ten-digit dialling in 613 and 819 became mandatory on October 21, 2006. Intraprovincial calls from rate centres with no local calling beyond a small fragment of their own area code were returning intercept messages if dialled as seven digits. Exchange protection in the National Capital Region was ended, except for the "dual dialability" scheme for government numbers on both sides of the river.[1]

Within two years, it became apparent that a new area code was necessary due to the continued number allocation problem--an issue exacerbated by the proliferation of cell phones and pagers. A geographic split was quickly ruled out. Local telephone companies did not want the expense and burden of changing existing customers' numbers, which would have required en masse reprogramming of cell phones. As a result, overlay area codes were proposed for both 613 and 819.

Area code 343, an overlay 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]

Carriers

The main incumbent local exchange carrier in 613 is Bell Canada, although there are some five independent companies serving rural exchanges—the Lansdowne Rural Telephone Company serving Lansdowne;[6] the North Frontenac Telephone Company serving Sharbot Lake and Parham;[7] the North Renfrew Telephone Company serving Beachburg, Westmeath, and the area outside of Pembroke;[8] the Roxborough Telephone Company serving Moose Creek;[9] and the Westport Telephone Company serving Westport.[10]

Also served by area code 613 and Bell Canada is Saint Regis, Quebec, a native reservation bordering Fort Covington, New York which straddles the Ontario-Québec-New York border. St. Regis - Fort Covington is a local call, despite being international.[11]

Further west, Rapides-des-Joachims, Quebec shares an exchange with adjacent Rolphton, Ontario.[12]
