The UK's national telephone numbering system is maintained by Ofcom, the country's regulator for the UK communications industries, and may change at any time. Please note that dialling codes are not linked to specific boundaries - some postcodes may cross over into a neighbouring area, and are approximate.

When dialling from the UK, remember to include the first 0 (the national trunk prefix). When dialling from outside the country, enter the country code (44) and omit the first 0 (zero).

STD (Subscriber Trunk Dialling), or 'Uniform Exchange Codes' are allocated to each telephone exchange in the UK, and are prefixed with the number 0 (zero), for example '01952'.
