Dialling questions, answered
How do I find out where a UK phone number is from?
Take the digits after the leading 0 and match the longest area code that fits — 01202 is Bournemouth, 020 is London. UK mobile numbers start 07 and have no area code, so they aren't tied to a place. The lookup on this page does the matching for you.
How many UK area codes are there?
Ofcom's National Numbering Scheme lists around 610 geographic dialling codes covering the UK, the Channel Islands and the Isle of Man. This directory covers 463 of them in detail, with the towns, postcode districts and neighbouring codes for each.
How do I dial a UK landline from abroad?
Dial your country's exit code, then 44, then the area code without its leading 0, then the local number. A Bournemouth number 01202 123456 is +44 1202 123456 from anywhere in the world.
Do UK mobile numbers have an area code?
No. UK mobile numbers begin 07 and are not geographic — the prefix identifies the original network the number was issued on, not a town, and numbers keep their prefix when they move network.
