Vernon, Centralia, Herrin, Salem, Metropolis, Fairview Heights, Collinsville, and Granite City.

Albion, Illinois
Albion is a city in and the county seat of Edwards County, Illinois, United States. The population was 1,971 at the 2020 census. The city was named "Albion" after an ancient and poetic reference to the island of Great Britain.

In 1818, following an irreconcilable fall-out between Birkbeck and Flower, the portion of English Prairie then settled on by Flower was given the name Albion. In 1821, the county seat of Edwards County was moved from Palmyra to Albion, eighteen miles to the west. However, residents of the larger Mount Carmel felt their town should be the county seat. Four companies of militia marched from Mount Carmel towards Albion to seize the county documents stored in the courthouse. The situation was eventually ...

Ten-digit Dialing
Ten-digit dialing is a telephone dialing procedure in the countries and territories of the North American Numbering Plan (NANP). It is the practice of including the area code of a telephone number when Dialling (telephony), dialing to initiate a telephone call. When necessary, the ten-digit number may be prefixed with the trunk code ''1'', which is referred to as ''1+10-digit dialing'' or ''national format''. History The implementation and expansion of the North American Numbering Plan between 1947 and 1992 preserved a long-standing practice in the United States and Canada that callers should only need to dial the local seven-digit telephone number when placing a call within the caller's exchange area or within the home numbering plan area (NPA). In seven-digit dialing, callers dial the three-digit central office code and the four-digit station number of the destination telephone if it resides in the same numbering plan area. Dialing of an area code before the telephone number, ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seven-digit Dialing
Seven-digit dialing is a telephone dialing procedure customary in some territories of the North American Numbering Plan (NANP) for dialing telephone numbers in the same numbering plan area (NPA). NANP telephone numbers consist of ten digits, of which the leading three are the area code. In seven-digit dialing it is not necessary to dial the area code. The procedure is also sometimes known as ''local format'' or ''network format''. History Originally, telephone exchanges consisted of manual switchboards operated by switchboard operators. Telephone numbers had typically two to four digits, depending on the size of the community. As the number of subscribers grew, multiple exchanges served individual neighborhoods of large cities. Multiple exchanges were identified by a central office name and typically four digits, such as "Pennsylvania 5000". A rural telephone number, often party line, had often up to four digits and a letter or letter and digits to indicate which of the multiple p ...

Central Office Code
The North American Numbering Plan (NANP) is an integrated telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Numbering Zone 1 and has the country code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The concepts of the NANP were devised originally during the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone companies in North America in Operator Toll Dialing. The first task was to unify the diverse local telephone numbering plans that had been established during the preceding decades, with the goal to speed call completion times and decrease the costs for long-distance calling, by reducing manual labor by switchboard operators. Eventually, it prepared the continent for direct-dialing of long-distance calls by customers, first possible in 1951, which expanded across the na ...

Area Code 217
Area codes 217 and 447 are telephone area codes in the North American Numbering Plan (NANP) for much of the central part of the U.S. state of Illinois. The numbering plan area (NPA) includes the state capital, Springfield, and Champaign, Urbana, Decatur, Taylorville, Lincoln, Danville, Effingham, Quincy, Rantoul, and Jacksonville. 217 was one of the original North American area codes created in 1947 and 447 was added to the same area in 2021 to form an all-services overlay. History In the original configuration of the first nationwide telephone numbering plan, the numbering plan area 217 included most of Metro East, the Illinois side of the St. Louis metropolitan area. In 1951, a slight boundary shift reassigned most of the southern portion of Metro East to area code 618, leaving the northern portion in 217. The only other significant change in boundaries was after September 1956, when its northern portion ( Peoria, Bloomington- Normal) was combined with part ...

Telephone Numbering Plan
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined world-wide, as well as within each of the administrative regions of the public switched telephone network (PSTN), and in private telephone networks. In public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or city code, which is a set of digits forming the most-significant part of the dialing sequence to reach a telephone subscriber. Within such regions designated by area codes, locally unique telephone number are assigned based on lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
