List of dialling codes in the United Kingdom

This is a list of telephone dialling codes in the United Kingdom. It is based on Ofcom's area code list, but includes defunct codes and historical changes, including the derivation of the two letter identities where known.[1][2]

Note that dialling codes do not correspond to any geographical boundaries, so 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.

  • 01999unused
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 is number is 999. It is likely to have been avoided so as to avoid confusion.

The length of the area code part and the local number part is found as follows:[45]

Number format NSN[46] Geographic area code
2+8 only 10 020, 023, 024, 028, 029
