Telephone dialling codes in the United Kingdom

This article lists the special numbers you dial before a phone number in the United Kingdom. These are called telephone dialling codes, and they help connect your call to the right place. Think of them like a postcode for phone calls! The way these numbers are set up is managed by Ofcom, which is an independent group that makes sure phone and internet services in the UK work well and are fair.

When you call someone in the UK, you usually dial a '0' before the area code. This '0' is like a special signal that you're making a long-distance call within the country. If you're calling from another country, you don't dial the '0'. Also, if you're calling someone in the exact same area as you, you often don't need to dial the area code at all. But if you're using a mobile phone or an internet-based phone service (like VoIP), you always need to dial the area code.

Phone Code Types

Different types of phone numbers start with different digits. Here's a quick guide to what the first few numbers mean:

Starting Digits What it's For
00 For making international calls (calls to other countries).
01 Most common codes for specific places or areas (like cities and towns).
02 Newer codes for specific places or areas.
03 Numbers that cost the same as calling a local landline, but can be anywhere in the UK.
04 Kept for future use.
05 Kept for future use (used to be for company numbers or internet calls).
06 Kept for future use.
07 For mobile phones, pagers, and personal numbers.
08 Freephone numbers (free to call) and numbers where the person you're calling shares the cost.
09 Premium-rate services (these cost more, like competition lines).

UK Dialling Codes List

Here are some of the main dialling codes in the UK. You'll see that some codes are "short" (like 02x) and some are "long" (like 01xxx). The grey text shows older codes that have changed.

Short Area Codes

These codes usually have 8-digit local numbers after them.

Short codes
02x yyyy yyyy (8-digit local number) 011x yyy yyyy (7-digit local number) 01x1 yyy yyyy (7-digit local number)
020 to 029 0113 to 0119 0121 to 0191
020 London (used to be 0171 and 0181)
023 Southampton and Portsmouth (used to be 01703 and 01705) 0113 Leeds (used to be 0532) 0121 Birmingham (used to be 021)
024 Coventry (used to be 01203) 0114 Sheffield (used to be 0742) 0131 Edinburgh (used to be 031)

Long Area Codes

These codes usually have 6-digit local numbers, or sometimes 5-digit numbers.

Long codes
01xxx (mostly six-digit local numbers) and 01xxxx (mostly five-digit local numbers)
01200 to 01470 01471 to 01762 01763 to 01999

Sometimes, a group of numbers is kept aside for use in TV shows or movies. This means you might hear a phone number like 01632 960000 on TV, but it won't actually connect to anyone!

How Long are Phone Numbers?

The total length of a UK phone number (including the area code but not the starting '0') is usually 10 digits. Here's how the numbers are structured:

Number Style Total Digits Example Area Codes
2-digit area code + 8-digit local number 10 020, 023, 024, 028, 029
3-digit area code + 7-digit local number 10 0113, 0114, 0115, 0116, 0117, 0118, 0121, 0131, 0141, 0151, 0161, 0191
4-digit area code + 6-digit local number 10 Most 01xxx codes (like 01200 to 01999)
4-digit area code + 6-digit local number, but some are 5+5 10 01387, 01539
4-digit area code + 6-digit local number, but some are 5+5 or 5+4 10 or 9 01697

Mixed 5+5 and 5+4 10 or 9 0169 77

Areas Where You Always Dial the Area Code

In some places, you always have to dial the area code, even if you're calling someone in the same town. This helps create more phone numbers for everyone.

Area Code Area Name When it Started
01202 Bournemouth 1 November 2012
01224 Aberdeen 1 October 2014
01273 Brighton 1 October 2014
01274 Bradford 1 October 2014
01642 Middlesbrough 1 October 2014
01908 Milton Keynes 1 October 2014

Overseas Territories

The UK also has some overseas territories. While places like Jersey, Guernsey, and the Isle of Man use UK-style area codes (like 01534, 01481, and 01624), most British Overseas Territories have their own phone systems. Calls to these places are treated as international calls.

North American Numbering Plan (NANP) Territories

Some territories use the North American Numbering Plan, which means their country code starts with +1.

Other Overseas Territories

These territories have their own unique international dialling codes.
