Where is this landline from?
Every UK landline number starts with an area code. It begins with 0, is three to five digits long and shows where the number was originally issued. After it comes the local number, and together they nearly always make 11 digits. You might also hear it called a dialling code, an STD code or simply a phone code.
There are 599 codes listed below, and you can filter them by town or digits. Each has its own page covering how to dial it, the cost of a call and what people have reported about numbers from that area. Ringing from outside the UK? Put +44 in front and leave off the first 0 (our +44 guide explains). Numbers beginning 03, 07 or 08 aren't tied to a place, so see 03 numbers and 07 mobile prefixes for those.

London 020 number blocks
0203, 0204, 0207 and 0208 aren't separate codes. London uses 020, and the next digit is just the start of the local number.

Is there one area code for the whole UK?
No. +44 is the UK's country code, used from abroad. Inside the UK each town or region has its own code starting with 0, such as 020 for London, 0161 for Manchester, 029 for Cardiff and 0141 for Glasgow.
How many digits is a UK area code?
Three to five, counting the leading 0: 020, 0121 and 01865 are all valid. The area code and local number together almost always make 11 digits, so the longer the code, the shorter the local part.
How do I look up the area code for a town?
Start typing the town name or the digits in the filter box on this page. Every code opens its own page with dialling instructions, call costs and any reports on numbers from that area.
How do I call a UK landline from another country?
Dial +44 (or 00 44), then the area code without its leading 0, then the local number. So the Glasgow number 0141 496 0456 becomes +44 141 496 0456.
Are 0203, 0207 and 0208 separate area codes?
No. They're all part of London's single 020 code. The digit after 020 is the first digit of the eight-digit local number, which is why 0207 numbers are properly written 020 7xxx xxxx. Each block has its own page below.
What area code is 07, 0800 or 0300?
They don't have one. 07 is for mobiles, 0800 and 0808 are freephone and 03 numbers are UK-wide. None of them points to a place.
The town is only half the answer
An area code tells you where a landline was issued, not who's using it. To find out whether a particular number has been causing trouble, search the whole thing at the top of this page. We put Ofcom's numbering records side by side with ratings from people who took the call, which is usually enough to separate a local plumber from a sales team using a borrowed number.
Don't be reassured just because the code is local. Callers can fake the number they show, and many deliberately pick your own area code because you're more likely to answer. If someone on a local-looking number asks for money or security details, hang up and call the organisation back on a number you already trust.
