List of dialling codes in the United Kingdom
This is a list of telephone dialling codes in the United Kingdom and the Crown Dependencies, 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.
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 long-distance 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 or through a VoIP service, such as BT's 'Digital Voice', the area code is always needed.

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.
In several area codes, a block of 1,000 numbers is set aside for use as fictional numbers for drama.[15][16]
Code length
[edit]The length of the area code part and the local number part is found as follows:[17]
Number format | NSN[notes 49] | Geographic area code |
---|---|---|
2+8 only | 10 | 020, 023, 024, 028, 029 |

4+6 only | 10 | All 01xxx area codes from 01200 to 01999 not otherwise mentioned. |
4+6 areas where part of range is assigned as 5+5 | 10 | 01387, 01539 |
4+6 areas where part of range is assigned as mixed 5+5 and 5+4 | 10 or 9 | 01697 |

The number format '5+4' refers to, e.g. Brampton, numbers using the (0169 77) xxxx format.[18]
Areas with mandatory area code dialling
[edit]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 |
---|---|---|
01202 | Bournemouth (BO2) | 1 November 2012[6] |
01224 | Aberdeen (AB4) | 1 October 2014[7] |
01273 | Brighton (BR3) | 1 October 2014[7] |
01274 | Bradford (BR4) | 1 October 2014[7] |
01642 | Middlesbrough (MI2) | 1 October 2014[7] |
01908 | Milton Keynes (WO8) | 1 October 2014[7] |
Overseas Territories
[edit]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
[edit]- Anguilla +1 (264)
- Bermuda +1 (441)
- British Virgin Islands +1 (284)
- Cayman Islands +1 (345)
- Montserrat +1 (664)
- Turks and Caicos Islands +1 (649)
Others
[edit]- British Antarctic Territory +44 (shared with the UK)
- British Indian Ocean Territory +246
- Falkland Islands and South Georgia and the South Sandwich Islands +500
- Gibraltar +350
- Saint Helena and Tristan da Cunha +290
- Tristan da Cunha also uses +44 (0)20[19][20]
- Ascension Island +247
- Akrotiri and Dhekelia +357 (shared with Cyprus)
- Pitcairn Islands +64 (shared with New Zealand)

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. - ^ a b 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.

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. - ^ (01229) ELNS area. Barrow-in-Furness numbers begin 2, 4, 5, 6, 8. Millom numbers begin 3, 7, 9.

- ^ (01396) Mixed area. Downpatrick numbers began 2, 3, 4, 5, 6, 8, 9 before 2000.
- ^ 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.
