Area code 250 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of British Columbia outside the Lower Mainland, including Vancouver Island–home to the provincial capital, Victoria–and the province's Interior region. In addition, the numbering plan area extends into the United States community of Hyder, Alaska, located along the Canada–United States border near the town of Stewart. The incumbent local exchange carriers that service the area code are Telus, Northwestel, and CityWest in the city of Prince Rupert.

Area code 250 was created on October 19, 1996, as a split of area code 604, which was retained by the Lower Mainland.Prior to 1996, 604 had been the sole area code in British Columbia for almost half a century. While British Columbia would have likely needed another area code in any event due to the province's growth in the second half of the 20th century, the split was hastened by Canada's system of number allocation. Canada does not use number pooling as a relief measure. Instead, each competitive local exchange carrier is allocated blocks of 10,000 numbers (corresponding to a single prefix) in each rate centre where it plans to offer service, even in the smallest hamlets. Once a prefix is assigned to a carrier and rate centre, it cannot be moved elsewhere, even when a rate centre has more than enough numbers to serve its customers. This has resulted in thousands of wasted numbers, a problem exacerbated by the proliferation first of fax machines and pagers and then cell phones.
By the middle of the first decade of the 2000s, 250 was already on the verge of exhaustion, again due to the number allocation problem and the continued proliferation of cell phones—particularly on Vancouver Island and in the larger cities in the Interior. Amid projections that 250 would be exhausted by January 2008, the Canadian Radio-Television and Telecommunications Commission began considering relief options in early 2007. Proposals included:
Several of the major landline and wireless providers in the 250 territory strongly favoured an overlay, saying it would be easier to implement than a split. They also wanted to spare themselves and their customers the expense and burden of changing their numbers, which would have required en masse reprogramming of cell phones.The proposal for a split would have forced Vancouver Island's residents to change their numbers for a second time in a decade.
The CRTC announced on June 7, 2007, that 778 would be expanded to become an overlay for the entire province starting that July 4. On that date, exchanges in 778 became available to Vancouver Island and Interior residents, and a permissive dialling period began across British Columbia, during which it was possible to make local calls with either seven or ten digits.Three CO prefixes in the 250 area code were reserved for use by Northwestel, as 13 of its 15 switches at the time could not handle multiple area codes, and its system could not accommodate ten-digit-dialling.
The CRTC decided on an overlay after concluding that there was not enough time to implement a split before 250 was due to exhaust in January 2008.Effective June 23, 2008, ten-digit dialling became mandatory throughout the entire province, and attempts to make a seven-digit call triggered an intercept message with a reminder of the new rule. After September 12, 2008, seven-digit dialling no longer functioned. Overlays have become the preferred method of area code relief in Canada, as they are an easy workaround for the number allocation problem as opposed to a split plan.
On June 1, 2013, area code 236 was implemented as a distributed overlay of area codes 250, 604, and 778. It was expected to be exhausted by May 2020.As a result, area code 672 was implemented on May 4, 2019, as an additional distributed overlay to relieve area codes 250, 604, 778, and 236.
The North American Numbering Plan (NANP) is a telephone numbering plan that encompasses twenty-five distinct regions in twenty countries primarily in North America, including the Caribbean. Some North American countries, most notably Mexico, do not participate in the NANP.
Area codes 905, 289, and 365 are area codes in the North American Numbering Plan (NANP) in the Golden Horseshoe region that surrounds Lake Ontario in Southern Ontario, Canada. It covers (clockwise) the Niagara Peninsula, the city of Hamilton, the regional municipalities of Halton, Peel, York, Durham, and parts of Northumberland County, but excludes the City of Toronto. 905 is the main area code, while 289 and 365 are overlay codes covering the same territory.
Area codes 754 and 954 are the area codes for Broward County, Florida, United States. Notable cities within 754 and 954 are Fort Lauderdale, Plantation, Hollywood, Sunrise, Pompano Beach, Coral Springs, Deerfield Beach, Davie, Weston, Dania Beach, and Pembroke Pines.
In telecommunications, an overlay plan is a telephone numbering plan that assigns multiple area codes to a geographic numbering plan area (NPA). Overlaying numbering plan area codes is practiced in territories of the North American Numbering Plan (NANP) to prevent exhaustion of telephone numbers and central office codes in growth areas.
Seven-digit dialing is a telephone dialing procedure customary in the territories of the North American Numbering Plan, for dialing telephone numbers in the local calling area. The procedure is also sometimes known as local format or network format.
Number pooling is a method of reallocating telephony numbering space in the North American Numbering Plan, primarily in growth areas in the United States.

Area codes 304 and 681 are telephone area codes in the North American Numbering Plan (NANP) for the entirety of the U.S. state of West Virginia. The numbering plan area (NPA) 304 was established in October 1947, with one of the original 86 area codes. Area code 681 was added to the same area in an overlay plan that took effect on March 28, 2009.

This includes the communities of Cumberland, Frederick, Hagerstown, Gaithersburg, Potomac, Bethesda, Rockville, Landover and Silver Spring.

Cities served by the area code include Altoona, Bradford, DuBois, Erie, Meadville, Oil City, Titusville, Johnstown, St. Marys, and Warren as well as the boroughs of State College, Brockway, Clearfield, Huntingdon, Mount Union, Bedford, Clarion, Punxsutawney, Tyrone, Ebensburg, Coudersport, Ridgway and Brookville. The 814 area is the only telephone area in Pennsylvania that is still served by a single area code: all the others are overlay areas.
The expansion of the North American Numbering Plan (NANP) is an anticipated requirement to provide more telephone numbers to accommodate future needs beyond the pool of ten-digit telephone numbers in use since the inception of the NANP in 1947. An April 2019 analysis estimated that the current numbering plan would not be exhausted until after the year 2049.
