The UK telephone numbering plan, also known as the National Numbering Plan and is regulated by the Office of Communications (Ofcom). A telephone numbering plan is a plan for allocating Telephone number ranges to countries regions areas and exchanges and to non-fixed telephone networks The Office of Communications (Y Swyddfa Gyfathrebiadau or as it is more often known Ofcom is the independent regulator and competition authority for the Communication
Since 28 April 2001, almost all normal geographic numbers and most non-geographic numbers are 10 or 11 digits long. This is a list of country calling codes defined by ITU-T recommendation E Every country has both a country calling code used to dial into a country and an international call prefix or international access code used to dial out Events 1192 - Assassination of Conrad of Montferrat (Conrad I King of Jerusalem, in Tyre, two days after his title Year 2001 ( MMI) was a Common year starting on Monday according to the Gregorian calendar. The overall structure of the UK's National Numbering Plan is:

For dialling the United Kingdom from overseas, Ofcom recommend that numbers be written in the form (with a three-digit geographic code) +44 xxx xxx xxxx. It is very common to see the form +44 (0)xxx xxx xxxx used instead, even in official documents, though this form is not recommended by Ofcom.  For callers within the United Kingdom the +44 is dropped and the number between the brackets used.

Note that unlike 03 numbers there is no uniform pricing for 05 numbers; BT charge a number of different rates depending on the number dialled. . Some are charged at geographic rate, others not, and unlike 03 numbers, other operators are not required to charge the same rates as BT for calling 05 numbers
Individual mobile phone companies are allocated different ranges within the 075xx, 077xx, 078xx and 079xx area codes. Changes to mobile numbers were mostly straight replacements, such as Vodafone customers on the 0378 block became 07778. Vodafone is a Mobile network operator headquartered in Berkshire, England, UK.

Although calls from UK landlines to landlines in the islands are charged at the same rate as those to other UK landlines (i. e. they are not treated as international calls), calls may be excluded from calling plans offering unlimited UK fixed line calls, and some mobile operators may also charge more.
Ofcom has also reserved certain number ranges for use in television dramas and films, so as to avoid the risk of people having their telephone numbers displayed, and receiving unwanted calls. This is similar to the use of fictitious telephone numbers in the United States and Canada with the digits 555. The United States of America —commonly referred to as the Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page In North America, Telephone numbers with the prefix 555 are widely used for Fictitious telephone numbers in Television shows Films In most of the large cities with three-digit area codes a range of numbers is reserved, usually all the numbers starting with the digits 4960. For fictitious numbers in other areas the area code 01632 is reserved; this code is not in use, although 0632 was used for Newcastle upon Tyne until the late 1980s (63 = NE). Newcastle upon Tyne ( (often shortened to Newcastle) is a city and Metropolitan borough of Tyne and Wear, England There are also reserved ranges for fictitious mobile, freephone, and premium rate numbers. For the 03 number range Ofcom has allocated 03069 990000 to 990999.
Not all numbers used in TV dramas come from the recommended ranges. For instance, the TV soap Coronation Street set in the Manchester 0161 code area uses numbers in the unallocated 0161 715 XXXX range. Coronation Street (commonly known as 'Corrie' is an award-winning Soap opera created by Tony Warren

For the protein involved in the synthesis of Major histocompatibility complex II see CLIP (protein. Both 999 and 112 are used to contact all emergency services: Police, Fire Service, Ambulance Service, Mountain Rescue, Coastguard and Cave Rescue. 999 is the United Kingdom 's and Ireland's official Emergency telephone number and Poland 's medical emergency number
Both numbers can be called from mobile telephones with the keylock on and if the mobile handset requires a PIN code to switch it on, both 999 and 112 can be called without entering in the PIN. Some mobile telephones will allow such calls to be made without a SIM card.
The chargeable number 101 (10p per call) is being introduced in stages, with an aim to cover all of England and Wales by 2008, for "non-urgent emergencies". As of November 2006 however, it was alleged that owing to low take-up in trial areas this proposal is on indefinite hold. However, in at least one pilot area the service, while proving to be popular with the public and considered a great success by the Local Authorities, has been withdrawn due to cancellation of Home Office funding.

Since the early 1990s speaking clock services have been available throughout Britain using the number 123 (before this exchanges in 'Director' areas (Birmingham, Edinburgh, Glasgow, Liverpool, London and Manchester) dialled 846 (TIM) and main exchanges in Non-Director areas originally used "952", later changing to "80" with the introduction of STD and eventually to "8081" as other recorded services were introduced on 80X1 codes). A speaking clock service is used by people who wish to know the correct and accurate Time. Some mobile operators allocate other services to 123 - such as customer services or voicemail etc.
The Post Office even produced dial centre labels for use in advertisements and film/TV with a mythical exchange called VINcent plus four digits. The numerical equivalent of VIN was 846 and all the caller got was the speaking clock in the big city 'Director' areas.

In November 1922 the General Post Office decided to adopt the Strowger system from the various systems it had tried and it was to include 'Directors' in the exchanges in London. The Director System was a system which made it possible to call subscribers at other Telephone exchanges without operator intervention Demonstration models of the 'director' exchange were shown by manufacturer ATM of Liverpool as part of the Post Office exhibits at the British Empire Exhibition at Wembley in 1924 and 1925. However, it was not until 1927 that the first 'Director' telephone exchange was brought into service in Holborn, London and rolled out progressively across Greater London. In the field of Telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls Holborn (ˈhoʊbɚn or /ˈhoʊbɝːn/ "ho bun" is an area of Central London, England London ( ˈlʌndən is the capital and largest urban area in the United Kingdom. A 3 digit code, represented by letters, identified the local exchange. Director schemes were gradually introduced in the other major cities of the UK — Birmingham, Edinburgh (although a relatively small city, it obtained seven-figure dialling for political reasons), Glasgow, Liverpool and Manchester. Birmingham ( ˈbɜːmɪŋəm Ber -ming-um Edinburgh ( ˈɛdɪnb(ərə Dùn Èideann) is the Capital of Scotland and is its second largest city after Glasgow. Glasgow (ˈglæzgoʊ is the largest city in Scotland and third most populous in the United Kingdom Liverpool ( is a City and Metropolitan borough of Merseyside, England along the eastern side of the Mersey Estuary
Subscriber Trunk Dialling (STD) was introduced in 1958 to allow a caller to call another telephone directly instead of via a manual telephone exchange operator. This is a list of United Kingdom telephony dialling codes including defunct codes Subscriber trunk dialling ( STD, also known as subscriber toll dialling) is a term for the UK Telephone system allowing subscribers to dial trunk Year 1958 ( MCMLVIII) was a Common year starting on Wednesday (link will display full calendar of the Gregorian calendar. In the field of Telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls Uniform exchange codes, usually called STD codes, were allocated for every exchange in the country, progressively as STD was rolled out. This process was not completed until 1979
The original concept was for STD to be a nationwide Director system, and in common with the Director system, the exchange codes were originally assigned based on two letters of the respective place's name and the corresponding numbers on a telephone dial. Year 1979 ( MCMLXXIX) was a Common year starting on Monday (link displays the 1979 Gregorian calendar) For example Aylesbury was given the STD code 0AY6, where the letter A can be found on the number 2 and the letter Y on the number 9. See also Aylesbury Urban Area Aylesbury is the County town of Buckinghamshire in south east England. The letter O became a zero, such as for Bournemouth: 0BO2 where BO = 20. Originally, where a place's name began with the letter 'O' the code would begin with two zeros, such as Oxford: 0OX2 where OX = 09. These codes starting with '00' were later reallocated, freeing the prefix 00 for use by calls to the Republic of Ireland, to radiophones and to premium rate numbers. Ireland ( Irish: Éire, ˈeːrʲə is a country in north-western Europe. A radiotelephone is a communications device that allows two or more people to talk using Radio. Premium-rate telephone numbers are Telephone numbers for Telephone calls during which certain services are provided and for which prices higher than normal are
For the Director areas a 2 or 3 digit code was used for the city. These were:
|01||London||See 01 for London below|
|021||Birmingham||(2 = B)|
|031||Edinburgh||(3 = E)|
|041||Glasgow||(4 = G)|
|051||Liverpool||(5 = L)|
|061||Manchester||(6 = M)|
The codes 071, 081, and 091 were reserved for later expansion, with the former two eventually being allocated to London (see below), and 091 to Tyne and Wear and Durham. London ( ˈlʌndən is the capital and largest urban area in the United Kingdom. Birmingham ( ˈbɜːmɪŋəm Ber -ming-um Edinburgh ( ˈɛdɪnb(ərə Dùn Èideann) is the Capital of Scotland and is its second largest city after Glasgow. Glasgow (ˈglæzgoʊ is the largest city in Scotland and third most populous in the United Kingdom Liverpool ( is a City and Metropolitan borough of Merseyside, England along the eastern side of the Mersey Estuary Durham (ˈdʌrəm in RP, locally ˈdʏrəm is a small city and main settlement of the City of Durham district of County Durham, England
The use of names was intended to provide a mnemonic for the exchange in the same way as for the Director system, but as more and more places were given STD codes the mnemonic link became more and more obscure, and this system became unworkable. All figure dialling refers to the change in the UK telephone numbering plan in 1966 when the three-digit numbers for local Telephone exchanges began to be The use of alphabetic exchange (area) codes was abandoned in 1966 in favour of all figure numbering. As such about 60% of current area codes are still based on the original alphabetic STD.
Until the late 1980s, calls to cities in the Republic of Ireland were made using short codes starting with 000:
As the network was upgraded, direct dialling became possible to the whole country, but this was not completed in the rural areas until 1988. Ireland ( Irish: Éire, ˈeːrʲə is a country in north-western Europe. Until then, some calls from the UK to Ireland were made through the operator and diverted to the "Irish Service".
This was discontinued in the late 1980s, so that all calls to the Republic of Ireland from the UK had to be dialled in the international format using the international access code (since 1995, 00) and country code (353). This is a list of country calling codes defined by ITU-T recommendation E
Although full international dialling is now used, calls from Northern Ireland landlines to landlines in the Republic are charged at UK national or local rates, and calls from Great Britain to the Republic are charged at a special "Republic of Ireland" rate, higher than inland rates, but lower than those for elsewhere in Western Europe. Northern Ireland (Tuaisceart Éireann Ulster Scots: Norlin Airlann) is a Country within the United Kingdom, lying in the northeast of See also Kingdom of Great Britain Great Britain (Breatainn Mhòr Prydain Fawr Breten Veur Graet Breetain is the larger of the two main islands Western Europe at its most general meaning means 'all the countries in the West of Europe ' Additionally, calls to Northern Ireland from the Republic of Ireland can be made without an international access code, but instead replacing the British 028 prefix with an Irish 048 area code which specifically covers Northern Ireland. For example, calling Belfast from London would be 028 90xx xxxx while calling Belfast from Dublin would be 048 90xx xxxx.
With growth in second phone lines, direct dial-in (DDI) lines, fax machines and multiple telecoms operators during the 1980s the demand for telephone numbers exceeded the available number ranges. A number of changes were made to the UK numbering plan. All these stages were planned out in one exercise in the early 1980s, though the exact dates for each stage was decided later.
The first major change was in May 1990, when the London 01 area code was replaced with 071 and 081. Exchanges in central London used the 071 code with the remaining exchanges using the 081 code and formed a ring around the 071 area. Although this effectively doubled the available numbers it was not the last change for the capital.
On "PhONEday", 16 April 1995, the digit "1" was inserted into all UK geographic area codes. Events 1178 BC - A Solar eclipse may have marked the return of Odysseus, legendary King of Ithaca, to his kingdom Year 1995 ( MCMXCV) was a Common year starting on Sunday. Events of 1995 Promotion of this day included special Easter Eggs. Under the new changes, for example, central London's 071 became 0171. This was with a view to reorganising the numbering plan, so that the first two digits would indicate the type of service called:
|Area code prefix||Service type|
|01||Geographic area codes|
|02||New geographic area codes|
|03||Geographic area code expansion|
|07||Mobile phones, pagers and personal numbering|
|08||Freephone and shared cost|
|09||Premium rate, similar to US 1 900 number range|
The international access code also changed on 'PhONEday', from 010 to 00. A toll-free, Freecall, Freephone, or 800 number is a special Telephone number, in that the Called party is charged the cost of the Premium-rate telephone numbers are Telephone numbers for Telephone calls during which certain services are provided and for which prices higher than normal are Five new area codes were introduced for cities that were running low on phone numbers — and a digit was prepended to each existing local number.

Most of the ranges with the given initial digits have now been exhausted, with new numbers being allocated whose local portions have a different initial digit. For example, the Sheffield range (0114) 2 has now been exhausted, and new numbers (other than those recycled from the (0114) 2 range) begin with (0114) 3. Similarly, newly allocated numbers in Leeds, Leicester and Bristol begin with 3, but in Nottingham, the new prefix is (0115) 8.
On 22 April 2000 the second phase of the plan came into operation, dubbed the "Big Number Change".

Note that although Southampton and Portsmouth are one code from a code structure and local dialling point of view, as of January 2006 calls between them are not local calls and the "codes" 023 80 and 023 92 are treated as separate by the BT site for determining local call area. London ( ˈlʌndən is the capital and largest urban area in the United Kingdom. Southampton ( IPA /ˌsaʊθˈhæmptən/ is the largest city in the county of Hampshire, on the south coast of England History See also History of Portsmouth There have been settlements in the area since before Roman times mostly being offshoots of Portchester, which Coventry ( is a city and Metropolitan borough in the County of West Midlands in England.

Northern Ireland (Tuaisceart Éireann Ulster Scots: Norlin Airlann) is a Country within the United Kingdom, lying in the northeast of
It is planned that the new codes will eventually cover a larger area than at present. For example, although 029 presently covers just the Cardiff area, it may in the future cover all of Wales.
The code for Northern Ireland is 028. The transition codes for Northern Ireland are shown below. These can be accessed from the Republic of Ireland using either the domestic code 048, or the international code +44 28. Ireland ( Irish: Éire, ˈeːrʲə is a country in north-western Europe.
The prefixes for existing numbers in Northern Ireland are split up into 7 groups, roughly based upon the county in which the main exchange is based. The initial digit of each phone number is based on the designated county - for example, the first county alphabetically is County Antrim so numbers in this county start 2. County Antrim ( Contae Aontroma or simply Aontroim in Irish) is one of six counties that form Northern Ireland, and one of nine counties The next county is County Armagh so numbers here start 3. County Armagh ( Contae Ard Mhacha in Irish - from the height of Macha) is a county in Ulster in the north east of Ireland One exception to this is the Greater Belfast area, initial digit 9, which is extended to include each adjacent former STD code area, including the towns of Bangor, (County Down) (91), Lisburn (92), Carrickfergus (93), Antrim (94) and Saintfield (97). Bangor (Beannchor is a large Town in County Down, Northern Ireland, with a population of 76403 people in the 2001 Census, making it the Lisburn (Lios na gCearrbhach meaning fort of the gamblers) is a predominantly Unionist city in Northern Ireland, south-west of and adjoining Belfast Carrickfergus ( is a large town in County Antrim, Northern Ireland. See also Saintfield Ontario County Ontario Canada Saintfield (in Irish: Tamhnach Naomh, ie Field of Saints is a market The encompassed former STD codes at some points extend to over 20 miles from Belfast itself.

In addition, mobile and pager numbers were all moved into the 07 range. Larne (&mdashthe domain of a Viking chieftain is a substantial seaport and industrial Town on the east coast of County Antrim, Northern Ireland County Antrim ( Contae Aontroma or simply Aontroim in Irish) is one of six counties that form Northern Ireland, and one of nine counties The City of Armagh ( is an ancient religious site of worship of both celtic paganism and Christianity and the oldest of the five cities in Northern Ireland, County Armagh ( Contae Ard Mhacha in Irish - from the height of Macha) is a county in Ulster in the north east of Ireland Newcastle (in Irish: An Caisleán Nua, ie The New Castle is a small town in County Down, Northern Ireland. County Down, ( Ulster Scots: Coontie Doun. is one of the nine counties that form the province of Ulster and one of six counties that form Enniskillen ( is the county town (and largest town in County Fermanagh and the west of Northern Ireland. County Fermanagh (fɚr'mænɘ Contae Fhear Manach or Fear Manach ('Men of Monach'in Irish) is the westernmost of the six counties that form Northern Limavady (lɪmə'vadi ( is a Market town in County Londonderry, Northern Ireland, with Benevenagh as a backdrop Omagh (pronounced /'omæ/) is the County town of County Tyrone in Northern Ireland, situated where the rivers Drumragh and Camowen Belfast ( is the capital city of Northern Ireland and the seat of government in Northern Ireland. Greater Belfast (Irish Mórcheantar Bhéal Feirste) is an area surrounding and including Belfast in Northern Ireland. Lisburn (Lios na gCearrbhach meaning fort of the gamblers) is a predominantly Unionist city in Northern Ireland, south-west of and adjoining Belfast Greater Belfast (Irish Mórcheantar Bhéal Feirste) is an area surrounding and including Belfast in Northern Ireland. Pagers moved into 076, while personal numbers moved to 070. Mobile numbers moved into the 077, 078 and 079 ranges. The exception to this was Manx Telecom mobiles, where the code became 07624 in order to match the 01624 used for landlines. Manx Telecom (Chellinsh Vannin is the primary Telecommunications provider in the Isle of Man. In addition, lo-call and national call numbers migrated to 08xxx and premium rate numbers to 09xxx.
The number change meant that London returned to a single area code again (as in the old 01 days), with no "inner/outer" split. Existing London numbers acquired the prefixes 7 or 8, but from that point on (020) 7xxx xxxx and (020) 8xxx xxxx numbers were assigned or reused anywhere in the London area covered by the single (city-wide) 020 code.
From June 2005 the regulator, Ofcom, ceased to allocate number blocks to suppliers in the 7xxx xxxx and 8xxx xxxx ranges. From this date onwards all number allocations were in the 3xxx xxxx range and can be used anywhere in the London 020 area. Although new blocks of 7xxx xxxx and 8xxx xxxx range numbers are no longer being allocated to suppliers, those that have not yet exhausted their existing blocks are able to continue to issue and re-issue them to their customers.
Numbers in the 020 0xxx xxxx and 020 1xxx xxxx number ranges have also been made available. However, these numbers cannot be dialled without the 020 code and are called "London National Dialling" numbers.
It is a common misconception that London still has more than one area code (i. e. "0207 & 0208"). This is incorrect in the sense that omitting the "0207" or "0208" (area) code will give a local number that cannot be connected as it is missing the first digit. Therefore, writing a London number as 020x xxx xxxx is incorrect and can lead to confusion when attempting to dial it. 
This misconception of area code and number separation is also seen in other areas of the country where an area code reduction was seen due to the Big Number Change, such as Reading numbers still being written 01189 xxxxxx, whereas the correct number sequence is (0118) 9xx xxxx, Coventry being written as 02476 xxxxxx, whereas the correct number sequence is (024) 76xx xxxx, Cardiff 029 being written as 02920 xxxxxx whereas the correct number sequence is (029) 20xx xxxx. The Big Number Change was an update of telephone dialling codes in the UK in response to the rapid late 1990s growth of telecommunications and impending exhaustion of numbers This is also similar in Sheffield, where numbers are often seen written as 01142 or missing the leading digit 2 when abbreviated (751234 instead of 275 1234 for example). 
This also occurs in some areas of Northern Ireland, that previously had 5-digit and 6-digit local numbers like in Banbridge (previously (018206) xxxxx), where numbers are still written as 028406 xxxxx instead of 028 406x xxxx. Banbridge ( is a rapidly growing Town in County Down, Northern Ireland. Locals still misquote the area code as 028406, seven years after the change. The same occurs in formerly six-digit code areas, such as Lisburn (previous (01846) xxxxxx) continues to frequently appear as 02892 xxxxxx.
Creating numbers beginning 06, to replace 070 numbers - sometimes confused with mobiles - is also being considered.
At the moment, companies such as Patientline use 070 numbers. There is no cap on caller charges.
Ofcom wants 070 and 06 numbers to have a price cap, and 07 numbers to be used exclusively for mobile phones.
Under plans, rates charged to people calling 08 phone lines would be made clearer by linking the cost of the call to the third digit. Numbers starting 080 would be free, while 082 would be cheaper than 089.
