What are the primary telephone area codes serving Ottawa and Eastern Ontario, and what is their relationship within the North American Numbering Plan?

The telephone area codes 613, 343, and 753 are designated for Ottawa and the surrounding region of Eastern Ontario, Canada, as part of the North American Numbering Plan (NANP). Area code 613 is one of the original area codes established in October 1947. Area code 343 was introduced as an overlay code in May 2010, and area code 753 was added as a further overlay code in March 2022. An overlay plan allows a new area code to cover the same geographic region as an existing one, thereby increasing the available number supply without altering existing assignments.

How did the geographic coverage of area code 613 evolve from its initial assignment in 1947?

Initially, in October 1947, area code 613 was assigned to a large numbering plan area that encompassed all of Ontario, except for the Golden Horseshoe region, which was served by area code 416. Over time, this vast area was split to accommodate growing demand. In 1953, the southwestern Ontario portion of 613 was combined with part of 416 to create area code 519. Subsequently, in 1957, the extensive northwestern portion of 613 was merged with the northern part of 519 to form area code 705. Since these splits, area code 613 has been geographically limited to Eastern Ontario.

What geographical boundaries define the area covered by area code 613 since its 1957 split?

Since the split in 1957, area code 613 has exclusively served Eastern Ontario. Its coverage extends from Brighton and Deep River in the west to Saint Regis, Quebec, in the east, encompassing the nation's capital, Ottawa, and its surrounding communities.

How did the proximity of Ottawa and Hull (now Gatineau) influence telephone dialing and number allocation within the 613 and 819 area codes?

Ottawa, Ontario, and its twin city Hull, Quebec (now part of Gatineau), share a local calling area, which historically created a unique dialing situation. For 46 years, calls between Ottawa and Hull could be completed using only seven digits. To maintain this seven-digit dialing and prevent conflicts, an exchange code protection scheme was implemented. This system reserved telephone numbers across both area codes (613 and 819) to ensure that identical seven-digit numbers were not assigned on both sides of the National Capital Region, even if the geographic distance was significant.

What was the purpose and effect of the exchange code protection scheme implemented for the Ottawa-Hull area?

The exchange code protection scheme was designed to preserve seven-digit dialing between Ottawa and Hull by preventing the assignment of duplicate telephone number prefixes across the border. Technically, it required that no two prefixes within the same local calling area be duplicates. However, the implementation reserved numbers across both area codes, meaning a 613 number used in Eastern Ontario could prevent the use of a corresponding 819 number in western Quebec, and vice versa, even in areas far from the National Capital Region. This reservation system contributed to number exhaustion.

What factors led to the exhaustion of telephone number supply in area codes 613 and 819 by the turn of the century?

Several factors contributed to the exhaustion of number supply. Canada's inefficient number allocation system meant that competitive local exchange carriers (CLECs) received large blocks of 10,000 numbers per prefix in every rate center they served, regardless of actual need. Once assigned to a rate center and CLEC, these numbers were unavailable for reassignment elsewhere, even if unused. Furthermore, the proliferation of cell phones and pagers, especially in larger cities, significantly increased demand. The exchange protection in the National Capital Region also exacerbated the issue by limiting the reassignment of numbers.

How did the number allocation system, particularly the handling of rate centers and CLECs, contribute to telephone number scarcity in areas like 613?

The system allocated blocks of 10,000 numbers (a full prefix) to each competitive local exchange carrier (CLEC) in every rate center where they offered service. Even small, unincorporated villages with no central office but listed as rate centers often received multiple blocks. This meant that numbers assigned to a specific rate center and CLEC were unavailable for use in other areas, even if those numbers were not being utilized. This practice, combined with larger municipalities having multiple rate centers and competing carriers, led to a significant number of unused but unavailable telephone numbers.

What is the significance of Canada not using number pooling as a relief measure for area code exhaustion?

Canada's decision not to implement number pooling meant that unused telephone numbers could not be efficiently reallocated from smaller, less populated rate centers to larger ones like Ottawa, Kingston, or Belleville. Number pooling is a method where available numbers are managed centrally and distributed as needed, preventing the waste of blocks of numbers in areas with low demand. Without it, many numbers remained tied up in specific rate centers, contributing to the overall exhaustion of the numbering pool.

When did ten-digit dialing become mandatory for area codes 613 and 819, and what was a consequence of this change?

Ten-digit dialing became mandatory for area codes 613 and 819 on October 21, 2006. A consequence of this was that intraprovincial calls dialed using only seven digits from rate centers with limited local calling capabilities began to receive intercept messages, indicating that the number was no longer valid for seven-digit dialing. The exchange protection in the National Capital Region was also ended, except for specific government numbers.

Why was an overlay area code, rather than a geographic split, chosen as the solution for the number exhaustion in the 613 region?

An overlay area code was chosen because local telephone companies wished to avoid the significant expense and logistical burden of reassigning existing customers' phone numbers. Reassigning numbers would have necessitated extensive reprogramming of devices, particularly cell phones. Overlays, which allow a new area code to cover the same geographic territory as an existing one, were seen as a simpler and less disruptive method to increase the available number supply.

What is an overlay plan in the context of area codes, and why is it preferred for number relief?

An overlay plan is a method used in telecommunications to introduce a new area code that covers the same geographic region as an existing one. This approach is preferred for number relief because it allows for an increase in the available telephone number supply without requiring existing customers to change their phone numbers. This avoids the considerable cost and inconvenience associated with number reassignments, such as reprogramming customer equipment.

When was area code 343 approved and activated as an overlay for the 613 numbering plan area?

Area code 343 was proposed as an overlay in 2007 and received approval from the Canadian Radio-television and Telecommunications Commission (CRTC) on September 10, 2008. It was subsequently activated for the region on May 17, 2010, which was earlier than initially anticipated.

What is the significance of area code 753 in relation to the 613/343 numbering plan area?

Area code 753 was assigned as an additional overlay code for the 613/343 numbering plan area. It was activated on March 26, 2022, further increasing the available telephone number supply for Ottawa and Eastern Ontario.

Is there a future area code planned for the 613/343/753 region, and if so, what is it and when is it reserved for?

Yes, area code 871 is reserved as the fourth area code for the region. It is planned for activation starting in May 2025, indicating the ongoing need for additional telephone number capacity in Eastern Ontario.

Who is the primary incumbent local exchange carrier for area code 613, and what are some of the independent companies serving rural exchanges within this area?

The main incumbent local exchange carrier in area code 613 is Bell Canada. However, several independent companies also serve rural exchanges, including the Lansdowne Rural Telephone Company (serving Lansdowne), the North Frontenac Telephone Company (serving Sharbot Lake and Parham), the North Renfrew Telephone Company (serving Beachburg, Westmeath, and areas outside Pembroke), the Roxborough Telephone Company (serving Moose Creek), and the Westport Telephone Company (serving Westport).

How does the Saint-Regis, Quebec exchange, served by area code 613, interact with a U.S. location?

The Saint-Regis, Quebec exchange, which covers the Mohawk nation territory of Akwesasne, straddles the borders of Ontario, Quebec, and New York. Calls made from Saint-Regis to Fort Covington, New York, are considered local calls, even though they cross an international border. This is facilitated by the 613 area code serving this specific Quebec location.

What is the relationship between Rolphton, Ontario, and Rapides-des-Joachims, Quebec, in terms of telephone exchanges?

Rolphton, Ontario, and Rapides-des-Joachims, Quebec, share a common telephone exchange. This means that despite being in different provinces, they are connected through the same central office infrastructure for telephone services, with Rolphton being served by area code 613.

What does the designation 'p' signify next to certain telephone numbers in the community list, and what is its implication?

The designation 'p' next to certain telephone numbers in the community list indicates that these numbers are 'Protected against assignment in both 819 and 613.' This protection is typically applied to numbers used by Government of Canada offices, ensuring their availability and preventing conflicts with other assignments within the affected area codes.

What area codes are geographically adjacent to the 613/343/753 region in Canada?

To the north, the 613/343/753 region is bordered by Quebec area codes 819 and 873. To the west, it is adjacent to Ontario area codes 905/289/365 and 705/249. To the east, it borders Quebec area codes 450 and 579.

Which U.S. area codes share a border with the 613/343/753 region?

The 613/343/753 region shares borders with U.S. area codes to the south. These include New York area codes 315/680 and 518/838.

What was the original purpose of area code 613 when it was established in 1947?

Area code 613 was one of the original 86 area codes assigned in October 1947 under the North American Numbering Plan. Its initial purpose was to provide telephone numbering capacity for a vast territory that covered most of Ontario, excluding the Golden Horseshoe area.

What specific issue did the dual dialability scheme address for federal government offices in Hull?

The dual dialability scheme was implemented for federal government offices in Hull, Quebec, to duplicate their entire allocation of multiple exchanges worth of numbers available in the 613 area code. This was part of the broader effort to manage the complexities arising from the Ottawa-Hull local calling area and the exchange code protection, ensuring continuity and accessibility for government communications.

How did the number of rate centers in a large municipality like Ottawa contribute to the problem of telephone number exhaustion?

Even after amalgamation into a single municipality, Ottawa retained 11 rate centers, plus portions of others. Each rate center, especially those with multiple competing carriers, received significant blocks of numbers. This fragmentation meant that even if a specific rate center had a surplus of numbers, they could not be easily transferred or reassigned to other rate centers within the same municipality or region that were experiencing shortages, thus contributing to overall exhaustion.

What is the role of the Canadian Radio-television and Telecommunications Commission (CRTC) in the assignment of new area codes?

The CRTC plays a crucial role in approving new area codes and overlay plans. For example, they approved the introduction of area code 343 for the 613 region on September 10, 2008, following proposals from telecommunications administrators.

What is the significance of the date October 21, 2006, in the context of area codes 613 and 819?

October 21, 2006, marked the date when ten-digit dialing became mandatory for calls within and between area codes 613 and 819. This change was a direct result of the increasing demand for telephone numbers and the exhaustion of available prefixes, necessitating a shift away from seven-digit dialing for many calls.

What was the initial geographic coverage of area code 416 before it was split from the 613 area?

Area code 416 was initially assigned to the Golden Horseshoe region of Ontario. The text states that area code 613 was assigned to all of Ontario except the Golden Horseshoe, which was covered by 416.

Which independent telephone company serves the area outside Pembroke, along with Beachburg and Westmeath?

The North Renfrew Telephone Company serves the area outside Pembroke, as well as Beachburg and Westmeath, all within the 613 area code.

What is the geographic extent of the Ottawa–Hull exchange as defined in the text, particularly concerning the 2001 amalgamation?

Following the 2001 amalgamation, the Ottawa–Hull exchange itself was defined to cover only the area that constituted the city of Ottawa prior to that merger. This includes the former suburbs of Nepean (central part) and Vanier, along with small sections of other urban communities. It does not encompass all areas that were later incorporated into the larger municipality of Ottawa.

How does the list of communities and central office codes help in understanding the structure of the 613/343/753 area?

The list of communities and their associated central office codes (prefixes) provides a granular view of how telephone numbering resources are distributed across the geographic area served by these codes. It shows which prefixes are assigned to specific towns and municipalities, illustrating the practical application of area code assignments and the distribution of telephone services.

What does the table summarizing Ontario area codes indicate about the neighbors of 613/343/753?

The table indicates that the 613/343/753 area code complex is bordered to the north by Quebec's 819/873 area codes, to the west by Ontario's 905/289/365 and 705/249 area codes, and to the east by Quebec's 450/579 area codes. To the south, it borders New York's 315/680 and 518/838 area codes.

What was the reason for implementing area code 343 as an overlay rather than a geographic split for the 613 region?

The primary reason for choosing an overlay for area code 343 was to avoid the significant costs and logistical challenges associated with reassigning existing phone numbers. This included the burden of reprogramming cell phones and other customer equipment, making the overlay a more practical solution for increasing number capacity.

What specific problem did the exchange code protection scheme attempt to solve between Ottawa and Hull?

The exchange code protection scheme was implemented to maintain seven-digit dialing between Ottawa and Hull (now Gatineau) by preventing the assignment of duplicate telephone numbers on either side of the National Capital Region. This ensured that calls could be placed using only seven digits without confusion or conflicts.

How did the proliferation of mobile devices contribute to the need for new area codes like 343 and 753?

The increasing popularity and widespread adoption of mobile phones and pagers significantly increased the demand for telephone numbers. Each mobile device requires a unique number, and this surge in demand, particularly in densely populated areas like Ottawa, quickly depleted the available number supply within the original 613 area code, necessitating the introduction of overlay codes.

This protection is typically applied to numbers used by Government of Canada offices to ensure their consistent availability and prevent conflicts with other number assignments.

What is the primary incumbent local exchange carrier for area code 613?

The primary incumbent local exchange carrier for area code 613 is Bell Canada.

When was area code 613 originally assigned within the North American Numbering Plan?

Area code 613 was one of the original North American area codes assigned in October 1947.

What was the consequence of Canada not using number pooling for telephone number relief?

The absence of number pooling meant that telephone numbers assigned to smaller rate centers, even if unused, could not be reassigned to larger centers experiencing shortages. This practice led to a significant waste of available numbers and contributed to the exhaustion of numbering resources.

What is the purpose of an overlay code like 343 or 753?

Overlay codes are introduced to increase the available supply of telephone numbers within an existing geographic area. They are applied over the existing area code(s), allowing for new number assignments without requiring customers to change their current phone numbers.

How did the Ottawa-Hull exchange protection scheme affect number availability in areas distant from the National Capital Region?

The exchange code protection scheme reserved numbers across both the 613 and 819 area codes to prevent duplicates in the Ottawa-Hull local calling area. This reservation applied even to areas geographically distant from the National Capital Region, meaning a 613 number used in Brighton, for example, could prevent the use of a corresponding 819 number in western Quebec, contributing to inefficient number allocation.

Understanding the Codes

Geographic Coverage

Area codes 613, 343, and 753 are part of the North American Numbering Plan (NANP) and serve Ottawa and the surrounding Eastern Ontario region in Canada. Area code 613 is one of the original area codes established in October 1947. Area code 343 was introduced as an overlay in May 2010, and 753 was added as a further overlay in March 2022, to accommodate the growing demand for telephone numbers in this densely populated and economically significant area.^[2]^[4]

Overlay Strategy

The introduction of overlay area codes (like 343 and 753) allows new numbers to be assigned within the existing geographic territory without splitting the original area code. This approach, while preserving existing numbers and avoiding the need for customers to change their phone numbers, necessitates ten-digit dialing for all calls within the overlay region.^[3] This strategy is often employed to efficiently manage number exhaustion, particularly with the proliferation of mobile devices and multiple lines per user.^[5]

The Ottawa-Hull Connection

A unique aspect of this region is the shared local calling area between Ottawa, Ontario, and Gatineau (formerly Hull), Quebec. This cross-provincial boundary calling area, established to maintain seven-digit dialing for decades, presented complex numbering challenges. Exchange code protection measures were implemented to prevent number conflicts on both sides of the Ottawa River, impacting number availability across the entire 613 and 819 numbering plan areas.^[1]

Historical Evolution

Initial Allocation and Splits

Area code 613 was initially assigned to a vast territory covering most of Ontario, excluding the Golden Horseshoe region. Over time, population growth and numbering needs led to splits: in 1953, the southwestern portion became area code 519, and in 1957, the northwestern portion was assigned area code 705. Since 1957, 613 has exclusively served Eastern Ontario, extending from Brighton and Deep River eastward.^[1]

Numbering Challenges and Solutions

Canada's number allocation system, particularly the practice of assigning large blocks of 10,000 numbers per prefix to each carrier in every rate center, led to significant number exhaustion. This inefficiency, coupled with the rise of mobile phones, strained the 613 and 819 pools. The need for ten-digit dialing became mandatory in 613 and 819 on October 21, 2006, ending the long-standing seven-digit dialing between Ottawa and Hull.^[1]

The exhaustion of available prefixes necessitated relief measures. Geographic splits were deemed impractical due to the cost and disruption of reassigning numbers. Consequently, overlay area codes became the preferred solution. Area code 343 was approved in 2008 and activated in 2010. Subsequently, area code 753 was approved in 2021 and activated in 2022. A fourth overlay, area code 871, is reserved for potential future use, anticipated around May 2025.^[2]^[3]^[4]^[6]^[7]^[8]

Telecommunications Providers

Incumbent and Independent Carriers

The primary incumbent local exchange carrier within the 613 area code is Bell Canada. However, several independent telephone companies serve specific rural exchanges, ensuring localized service delivery. These include:

Lansdowne Rural Telephone Company (serving Lansdowne)
North Frontenac Telephone Company (serving Sharbot Lake and Parham)
North Renfrew Telephone Company (serving Pembroke outskirts, Beachburg, Westmeath)
Roxborough Telephone Company (serving Moose Creek)
