List of dialling codes in the United Kingdom
Template:Short description Template:Use British English Template:Use dmy dates
The United Kingdom and the Crown Dependencies have adopted an open telephone numbering plan in the 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 few areas that do require this. When calling from a mobile telephone or through a Voice over IP service, the area code is always needed.
Code prefixes
| Initial digits | Service type |
|---|---|
| 00 | International call prefix |
| 01 | Geographic area codes since 1995 |
| 02 | Geographic area codes since 2000 |
| 03 | Non-geographic numbers charged at geographic rates |
| 04 | Reserved |
| 05 | Reserved (previously, corporate numbering and VoIP) |
| 06 | Reserved |
| 07 | Mobile telephony, paging services and personal numbering |
| 08 | Freephone and revenue share non-geographic numbers |
| 09 | Premium-rate services |

ELNS denotes Extended Linked Numbering Scheme areas, where an area code is associated with more than one place name.
| Long codes | |||||
|---|---|---|---|---|---|
| 01xxx [mostly six-digit local numbers][notes 12] and 01xxxx [mostly five-digit local numbers][notes 13] (but not 01x1 codes) | |||||
| 01200 to 01470 | 01471 to 01762 | 01763 to 01999 | |||

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.[14][15]
Code length
The length of the area code part and the local number part is found as follows:[16]
| Number format | NSN[notes 49] | Geographic area code |
|---|---|---|
| 2+8 only | 10 | 020, 023, 024, 028, 029 |
| 3+7 only | 10 | 0113, 0114, 0115, 0116, 0117, 0118, 0121, 0131, 0141, 0151, 0161, 0191 |
| 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 Template:Grey | 01697 |
| Mixed 4+6 and 4+5 | 10 or 9 | 01204, 01208, 01254, 01276, 01297, 01298, 01363, 01364, 01384, 01386, 01404, 01420, 01460, 01461, 01480, 01488, 01527, 01562, 01566, 01606, 01629, 01635, 01647, 01659, 01695, 01726, 01744, 01750, 01827, 01837, 01884, 01900, 01905, 01935, 01949, 01963, 01995 |
| Mixed 4+6 and 4+5 areas where part of range is assigned as 5+5 | 10 or 9 | 01524, 01768, 01946 |
| 5+5 only | 10 | 0138 73, 0152 42, 0153 94, 0153 95, 0153 96, 0169 73, 0169 74, 0176 83, 0176 84, 0176 87, 0194 67 |
| Mixed 5+5 and 5+4 | 10 or 9 | 0169 77 |
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 |
|---|---|---|
| 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
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 are not part of the UK telephone numbering plan. Some are members of 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
Country code: 1
- Anguilla: area code 264
- Bermuda: area code 441
- British Virgin Islands: area code 284
- Cayman Islands: area code 345
- Montserrat: area code 664
- Turks and Caicos Islands: area code 649
Others
- 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
- Ascension Island: +247
- Akrotiri and Dhekelia: +357 (shared with Cyprus)
- Pitcairn Islands: +64 (shared with New Zealand)
