Every UK landline number starting 01 or 02 belongs to
a geographic area code tied to a town or city. Below are in-depth
guides to the dialling codes of the UK’s biggest cities, followed by an A–Z
directory of all 599 UK dialling codes — each with the
local number format, call charges, the providers holding its number ranges and advice
on spotting spoofed scam calls. Looking for a different kind of number? See our
guides by number type or browse
every UK number range by prefix.
For the three- to six-digit codes that are not area codes at all —
7726, 159, 999, 101 and the rest — see the
UK short codes directory, and
for the providers holding these ranges see the
UK network operators hub.
