List of dialling codes in the United Kingdom

This is a list of telephone dialling codes in the United Kingdom, which adopts an open telephone numbering plan for its public switched telephone network. The national telephone numbering plan is maintained by Ofcom, an independent regulator and competition authority for the UK communications industries. This list is based on the official standard, but includes defunct codes and historical changes, including the derivation of the two letter identities, in cases where known.[1][2][3] Dialling codes do not correspond to specific political boundaries: for example, the Coventry dialling code covers a large area of Warwickshire and the Manchester dialling code covers part or all of several neighbouring towns.

Telephone dialling codes in the United Kingdom

When dialling within the country, all area codes are preceded by the national trunk prefix 0, which has been included in all listings in this article. 0 was traditionally the number dialled for the operator for trunk calls before subscriber trunk dialling (STD) was introduced and so was retained as a prefix for direct-dialled calls. In the majority of areas, the area code still corresponds to the original STD letter code. When dialling from abroad, the 0 prefix is not dialled. When dialling within the same area, the area code is not needed, save for a handful of areas that do require this. When calling from a mobile telephone, the area code is always needed.

  • 01999 — unused
The code 0999 was used for dialling by PO operators only to mobile relief exchanges in the Glasgow area in the 1970s.
This code is now unused, and this may simply be because previously it was 0999 and the emergency telephone number is 999. It is likely to have been avoided so as to avoid confusion.

01426, 01523 and other non-standard 01 prefixes were briefly used for pagers[8] in the late 1990s and then moved to new 076 prefixes in the Big Number Change in 2000/2001.

The 01632 area code is set aside for use as fictional numbers for drama as are parts of a number of other area codes.[14][15]

Code length

The length of the area code part and the local number part is found as follows:[16]

The number format '2+8' refers to, e.g. London, numbers using the (020) xxxx xxxx format.[17]

The number format '5+4' refers to, e.g. Brampton, numbers using the (0169 77) xxxx format.[17]

Areas with mandatory area code dialling

In the following areas, the area code must be included when dialling local numbers. This enables local numbers to start with 0 or 1 and was introduced to increase the number of available telephone numbers within these areas.

Area code Area code name Date effective
01202Bournemouth (BO2)1 November 2012[6]
01224Aberdeen (AB4)1 October 2014[7]

Overseas Territories

Unlike the Crown Dependencies of Jersey, Guernsey and the Isle of Man which use the UK area codes 01534, 01481 and 01624 respectively, telephone numbers in British Overseas Territories do not come under the UK telephone numbering plan. Some are within the North American Numbering Plan (NANP). These calls are treated as international calls. Below are the access codes for the overseas territories:

North American Numbering Plan

Others

Notes
  1. (020) The codes 0207 & 0208 do not exist: London is under a single code, 020. Local numbers have eight digits and currently begin 0, 3, 4, 7, or 8.
  2. Area code changed as a part of the Big Number Change in 2000.
  3. Area code changed as a part of phONEday in 1995.
  4. Area code changed in 1990.
  5. (023) Wide area. Southampton numbers begin 80, 81, 82. Portsmouth numbers begin 92, 93, 94. Local numbers have eight digits.
  6. (024) Wide area. Coventry numbers begin 75, 76, 77. Local numbers have eight digits.
  7. (028) Eight-digit local numbers begin as follows: Ballycastle: 20, Martinstown: 21, Ballymena: 25, Ballymoney: 27, Larne: 28, Kilrea: 29, Newry: 30, Armagh: 37, Portadown: 38, Banbridge: 40, Rostrevor: 41, Kircubbin: 42, Newcastle (Co. Down): 43, Downpatrick: 44, Enniskillen: 66, Lisnaskea: 67, Kesh: 68, Coleraine: 70, Derry: 71, Limavady: 77, Magherafelt: 79, Carrickmore: 80, Newtownstewart: 81, Omagh: 82, Ballygawley: 85, Cookstown: 86, Dungannon: 87, Fivemiletown: 89, Belfast: 90 and 95, Bangor (Co. Down): 91, Lisburn: 92, Ballyclare: 93, Antrim: 94, Saintfield: 97. When dialling Northern Ireland from the Republic of Ireland, it may be cheaper to dial 048 xxxx xxxx rather than the normal 00 44 28 xxxx xxxx (see ComReg website Archived 2015-11-08 at the Wayback Machine).
  8. (0118) Numbers in Reading separately migrated to 0118 several years after PhONEday and a couple of years before the BigNumber change. Local numbers have seven digits and begin 3, 4 or 9.
  9. Area code changed in 1998.
  10. (029) Wide area. Cardiff numbers begin 20, 21, 22. Local numbers have eight digits.
  11. (0191) ELNS area. Tyneside numbers begin 2, 4, 6, 8 (North Tyneside/Newcastle 2, 6 – South Tyneside/Gateshead 4, 8). Durham numbers begin 3, 9. Sunderland numbers begin 5, 7. Local numbers have seven digits.

  12. There are some places with the standard (01xxx) four-digit area code but which have both six-digit and five-digit local numbers, as described at Telephone numbers in the United Kingdom. These codes include 01204, 01208, 01254, 01276, 01297, 01298, 01363, 01364, 01384, 01386, 01404, 01420, 01460, 01461, 01480, 01488, 01524 (mixed), 01527, 01562, 01566, 01606, 01629, 01635, 01647, 01659, 01695, 01726, 01744, 01750, 01768 (mixed), 01827, 01837, 01884, 01900, 01905, 01935, 01946 (mixed), 01949, 01963 and 01995.
  13. There are some places with an (01xx xx) five-digit area code. These areas can potentially have either or both five-digit and four-digit local numbers. Nowadays only Brampton (0169 77) has four-digit local numbers (0169 77) 2xxx and (0169 77) 3xxx, as well as five-digit local numbers (0169 77) 4xxxx to (0169 77) 9xxxx, as described at Telephone numbers in the United Kingdom and at Ofcom. "Code and number blocks – 1600 00 to 1799 99". Office of Communication. Archived from the original on 2012-09-18.

  14. This change happened prior to PhONEday (16 April 1995); the new code is not to be confused with the current allocations of dialling codes commencing 02 to 09, as this code would have changed again (mostly by adding the '1' after initial zero) on PhONEday.
  15. (01229) ELNS area. Barrow-in-Furness numbers begin 2, 4, 5, 6, 8. Millom numbers begin 3, 7, 9.
  16. (01247) Mixed area. Bangor numbers began 2, 3, 4, 5, 6, 8, 9 before 2000.
  17. All Northern Ireland 01xx xx "mixed" areas migrated to the new 028 area code in the Big Number Change in 2000.

  23. (01387) Mixed area. Dumfries numbers begin 2, 4, 5, 6, 7, 8, 9.

  25. (01396) Mixed area. Downpatrick numbers began 2, 3, 4, 5, 6, 8, 9 before 2000.
  26. Historical note: In fact 0402 was equivalent to 07088, and translated as such for call connection, but (say) 070884 xxxxx was too long a dial string for the numbering plan, so 04024 xxxxx was used.
  27. (01423) ELNS area. Boroughbridge numbers begin 3, 4, 9. Harrogate numbers begin 2, 5, 6, 7, 8.
  28. (01430) ELNS area. Market Weighton numbers begin 6, 7, 8, 9. North Cave numbers begin 2, 3, 4, 5.

  44. (01890) ELNS area. Ayton numbers begin 5, 6, 7, 9. Coldstream numbers begin 2, 3, 4, 8.
  45. Historical note: 0930 was a Premium rate number range, however 0930 7 was used by One2One mobile phones. Where switchboards blocked 0930 as Premium rate, the mobile phones could not be contacted. 0961 7 was mirrored onto this allocation to get round the problem.
