A guide to phone numbers in the United Kingdom.

How do UK phone numbers work?

All numbers start with 0, which historically, would tell the exchange to dial outside of the local area. On some landlines that don't use VoIP, the numbers after the area code can be dialed on their own to reach a phone in the same area

To dial outside of the UK, 00 is used as an access, although most modern phones will convert + to 00 for you. The UK's international code is +44, and the 0 is omitted when dialing from abroad, so 01632 678 986 would become +44 1632 678 986

UK telephone numbers are regulated by Ofcom, Ofcom's complete UK numbering plan can be found here

This is a list of the types of numbers:

The amount of numbers after the area code can vary a large amount, in the vast majority of areas, a landline number is in the format: 01xxx yyy yyy, however the area code (shown as the letter x) can be 1,2 or 4 digits long as well. There is a complete list of the variation in landline numbers here. For example, a London number could be (020) xxxx xxxx, but a number in Brampton could be (016977) xxxx, as you can see, in some areas the area code is shorter or longer than most people expect.

Mobile numbers are much more consistent all mobile numbers use the format (07xxx) xxxxxx, similar to the most common land line format.

There are also non-geographic numbers, introduced in 2007, these are always charged at the rate you pay for landline calls, and are mainly used by large businesses. These are in the format of (03xx) xxx xxxx

UK Emergency numbers

There are various emergency numbers in the UK, the vast majority of them are 3 digit numbers. Here is a (hopefully comprehensive) list:
