List of dialling codes in the United Kingdom

thumb|300px|Map of telephone dialling codes in the United Kingdom and the Crown Dependencies, 2019

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, the 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, where known. Dialling codes do not correspond to political boundaries: for example, the Coventry dialling code covers a large area of Warwickshire, and the Manchester 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.

In several area codes, a block of 1,000 numbers is set aside for use as fictional numbers for drama.

Code length

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

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.
