Encyclopedia > UK telephone numbering plan

The UK telephone numbering plan, also known as the National Numbering Plan, is regulated by the Office of Communications (Ofcom), which replaced the Office of Telecommunications (Oftel) in 2003. A telephone numbering plan is a plan for allocating telephone number ranges to countries, regions, areas and exchanges and to non-fixed telephone networks such as mobile phone networks. ... Ofcom is a regulator for communication industries in the United Kingdom. ... Ofcoms logo The Office of Communications, usually known as Ofcom, is the UKs communications regulator. ...

Format

General format

Following the changes in 1995, 2000 and 2001, the numbering range in use is as follows. Note that the initial "0" of a telephone number (called the trunk prefix) is not properly considered part of the area code but is, rather, the national long distance calling prefix, and thus (for example) 023 is a "two-digit" area code.

  • Calls originating in the UK
    • The leading "0" is only required for calls originating in the UK.
    • Likewise, "00" is the UK dialling prefix for international calls (to be followed by the international country code and number).
  • Calls originating from outside the UK
    • Note: The leading "0" should be omitted for all international calls and replaced with the international country code for the UK: +44.

Geographic numbering

  • (01xxx) xxx xxx — a four digit area code and up to six digit subscriber number. The break is placed in the middle by convention but this does not reflect normal allocation blocks. e.g:
01382 Dundee 38 = DU
01482 Hull 48 = HU
01582 Luton 58 = LU
  • (01x1) xxx xxxx — the geographical number format for the larger cities, a three digit area code, with a seven digit subscriber number where the first three digits identifies an area within the city.
0121 Birmingham 2 = B
0131 Edinburgh 3 = E
0141 Glasgow 4 = G
0151 Liverpool 5 = L
0161 Manchester 6 = M
0171 Used for inner London until 2000
0181 Used for outer London until 2000
0191 Newcastle-upon-Tyne/Gateshead/Sunderland (Wearside)/Durham 9 = W
  • (011x) xxx xxxx — the geographical number format for a second tier of large cities, a three digit area code, with a seven-digit subscriber number, e.g:
0113 Leeds formerly 0532 (53 = LE)  
0114 Sheffield formerly 0742 (74 = SH)
0115 Nottingham formerly 0602 (60 = NO)  
0116 Leicester formerly 0533 (53 = LE)
0117 Bristol formerly 0272 (27 = BR)
0118 Reading Phased in between 1996 and 1998
  • (02x) xxxx xxxx — the geographical number format for areas of high population densities which had run out of spare numbers using six or seven digit numbers and now the most common format, a two digit area code with an 8-digit subscriber number. The short area code is known as a wide area code. e.g:
020 London
023 South Hampshire (Southampton and Portsmouth)
024 Coventry (may also become code for the rest of the West Midlands) [citation needed]
028 Northern Ireland (e.g. Belfast 028 90xx xxxx, Omagh 028 82xx xxxx)
029 Cardiff (Cardiff 029 20xx xxxx)  (may also become code for the rest of Wales)[citation needed]
  • (01xxx) xxxxx, (01xxxx) xxxxx, (01xxxx) xxxx — used for smaller towns where the subscriber number is either four or five digits long; note that the STD code and the subscriber number don't always total eleven digits, e.g:
(01204) xxxxx Bolton
(015396) xxxxx Sedbergh
(016977) xxxx Brampton

Callers would be charged at the same rate as existing area codes which start with 01, or 02. This means that customers benefiting from 'free' minutes on mobiles or landlines would also be able to call these numbers. '0870', '0845' and sometimes the freephone '0800' numbers are not usually covered under such call plans.[1]


National Dialling Only ranges

These ranges have subscriber numbers beginning with the digits '0' or '1', eg:

01332 050 xxx Derby
01382 006 xxx Dundee
0141 005 xxxx Glasgow
020 0003 xxxx London

In order to avoid confusion with codes beginning with these digits, the area code must always be dialled, even from within the same geographic exchange. Traditionally these have not been used for inbound calls, although these are now being allocated to some Voice over Internet Protocol (VoIP) services[citation needed]. This has been problematic as some mobile phone operators in the UK do not allow access to these ranges, and there may also be difficulty accessing these numbers from outside the UK.

Although calls from UK landlines to landlines in the islands are charged at the same (long-distance) rate as those to geographic numbers in the UK, calls may be excluded from calling plans offering unlimited UK fixed line calls, and some mobile operators also charge more.


Drama numbers

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. 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). There are also reserved ranges for fictitious mobile, free and premium rate numbers. In North America, telephone numbers with the prefix 555 are widely used for fictitious phone numbers in television shows, films and other types of fictional media. ...

The UK has two free emergency numbers — the traditional 999, which is still widely used, and the EU standard 112, which can be used in all member states of the European Union. Both 999 and 112 are used to contact all emergency services: Police, Fire Service, Ambulance Service, Mountain Rescue, Coastguard and Cave Rescue. 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 appears that owing to low take-up in trial areas this proposal is on indefinite hold. 999 is the United Kingdoms and Irelands emergency telephone number and Polands medical emergency number. ...

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 Glasgow) 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). Some mobile operators allocate other services to 123 - such as customer services or voicemail etc. A speaking clock service is used for people who wish to know the correct and accurate time. ...


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.

History

The telephone service in the United Kingdom was originally provided by private companies and local councils. But by 1912–13 [2] all except the telephone service of Kingston upon Hull, Yorkshire and Guernsey had been bought out by the Post Office. The Post Office also operated telephone services in Jersey until 1923 and the Isle of Man until 1969 when the islands took over responsibility for their own postal and telephone services - although the Isle of Man remained part of British Telecom until 1987.

Post Office Telecommunications was reorganised in 1980–81 [3] as British Telecommunications (British Telecom, or BT), and was the first major nationalised industry to be privatised by the Conservative government. The Hull Telephone Department was itself reconstituted as Kingston Communications, in 1987; it was sold by Hull City Council in the late 1990s and celebrated its centenary in 2004.

Director system

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. 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. 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 all-figure dialling for political reasons), Glasgow, Liverpool and Manchester. The Director System was introduced to six cities in the UK from 1922 following the introduction of the automatic telephone exchange in the UK in 1912. ...

Introduction of area codes

Subscriber Trunk Dialling (STD) was introduced in 1958 [4] to allow a caller to call another telephone directly instead of via a manual telephone exchange operator. 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 [5]. Notes A Note that the codes 0207 & 0208 do not exist: London is united under a single code, 020. ... Subscriber trunk dialling (STD) (also known as subscriber toll dialling) is a term for the UK telephone system allowing subscribers to dial trunk calls without operator assistance. ... Year 1958 (MCMLVIII) was a common year starting on Wednesday (link will display full calendar) of the Gregorian calendar. ... A telephone operator manually connecting calls with patch cables at a telephone switchboard. ... Also: 1979 by Smashing Pumpkins. ...


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. 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. 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. Aylesbury is the county town of Buckinghamshire in south east England. ... It has been suggested that this article or section be merged with Two-way 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 charged. ...


For the Director areas a 2 or 3 digit code was used for the city. These were:

Area code City Notes
01 London See 01 for London below
021 Birmingham (2 = B)
031 Edinburgh (3 = E)
041 Glasgow (4 = G)
051 Liverpool (5 = L)

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.

All figure dialling

Main article: All figure dialling

The use of names was intended to provide a mnemonic for the exchange, but as more and more places were given STD codes the mnemonic link became more and more obscure, and this system became unworkable. 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. 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 assigned without reference to any correspondence to the letters on the dial. ...


Calls to the Republic of Ireland

Until the late 1980s, calls to cities in the Republic of Ireland were made using short codes starting with 000:

 Dublin 0001 (Dublin 01 Area) Cork 0002 (Cork 021 Area) Dundalk 0004 (Dundalk 042 Area) Waterford 0005 (Waterford 051 Area) Limerick 0006 (Limerick 061 Area) Letterkenny0007 (Letterkenny 074 Area) Galway 0009 (Galway 091 Area) 

As the network was upgraded, direct dialling became possible to the whole country, but this was not completed in the rural areas until 1988. 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).


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 "Irish Republic" rate, higher than inland rates, but lower than those for elsewhere in Western Europe. Northern Ireland is a part of the United Kingdom lying in the northeast of the island of Ireland, covering 5,459 square miles (14,139 km², about a sixth of the islands total area). ... The borders of Western Europe were largely defined by the Cold War. ...


Number shortage

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.


01 for London

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.


PhONE Day

On "PhONE Day", 16 April 1995, which was also Easter Sunday in Western Christianity, the digit "1" was inserted into all UK geographic area codes. 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: April 16 is the 106th day of the year in the Gregorian calendar (107th in leap years). ... Year 1995 (MCMXCV) was a common year starting on Sunday (link will display full 1995 Gregorian calendar). ...

Western Christianity is a form of Christianity that consists of the Latin Rite of the Catholic Church and Protestantism. ...

This is also the case for Bristol, the range 0117 9xx xxxx has been exhausted. New numbers issued now take the form of 0117 3xx xxxx.

Big Number Change

Main article: Big Number Change

On 22 April 2000 the second phase of the plan came into operation, dubbed the "Big Number Change". With 02* freed up by the previous reorganisation, it could be re-used. The Big Number Change was the name given to the update of dialling codes in the U.K. in response to the rapid late 1990s growth of telecommunications and impending exhaustion of numbers. ... is the 112th day of the year (113th in leap years) in the Gregorian calendar. ... 2000 (MM) was a leap year starting on Saturday of the Gregorian calendar. ...

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.

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. It is interesting that AW (All Wales) and CY (Cymru, the Welsh for Wales) are both represented on a telephone keypad as 29. Welsh redirects here, and this article describes the Welsh language. ...


The code for Northern Ireland is 028, which can be represented by both BT (for Belfast) or AU (for All Ulster).


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.


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. The next county is County Armagh so numbers here start 3. One exception to this is the Greater Belfast area, initial digit 9, which is extended to include each adjacent former STD code area, including towns such as Antrim, Bangor and Saintfield.

In addition, mobile and pager numbers were all moved into the 07 range. Pagers moved into 076, while personal numbers moved to 070. Mobile numbers moved into the 077, 078 and 079 ranges.

020 for London

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 "020" area code will give a local number that can be dialled from any other "020" line, so the commonly seen spacing 020x xxx xxxx, does not conform to the normal practice of separating the area code by a space.[3] // Local numbers and area codes A full British fixed telephone number is divided into two parts: an STD code (area code) and a local number. ...


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. This also occurs in some areas of Northern Ireland, that previously had 5-digit local numbers lik in Banbridge (previously 018206 xxxxx), where numbers are still written as 028406 xxxxx instead of 028 406x xxxx. Locals still misquote the area code as 028406, seven years after the change. The Big Number Change was the name given to the update of dialling codes in the U.K. in response to the rapid late 1990s growth of telecommunications and impending exhaustion of numbers. ... WGS-84 (GPS) Coordinates: 54. ...


New '06' Code

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.

The UK telephone numbering plan, also known as the National Numbering Plan, is regulated by the Office of Communications (Ofcom), which replaced the Office of Telecommunications (Oftel) in 2003.
Note that the initial "0" of a telephone number (called the trunk prefix) is not properly considered part of the area code but is, rather, the national long distance calling prefix, and thus (for example) 023 is a "two-digit" area code.
Likewise, "00" is the UK dialing prefix for international calls (to be followed by the international country code and number).
