UK Phone Numbers

All UK phone numbers adhere to the E.164 set of standards established by the ITU-T. Both landline and mobile numbering. Each device on the PSTN is recognized by a globally unique number according to the international telephone numbering scheme that is laid forth in this collection of standards. An international E.164 number is made to contain all the information required for a call or SMS to be successfully routed to a particular subscriber on a nation’s publicly switched telephone network. This holds true for both UK phone numbers and UK uk code numbers.

How to Call Numbers in the UK

A UK landline number’s initial digit designates a particular region. The UK phone code or dialing code are terms used to describe it. A UK landline phone number will typically be formatted as follows: area code + landline number.

  • You may call the UK from another nation using UK code number 44.
  • Area codes in the UK are two, three, four, or, in rare cases, five digits long (after the initial zero). Large cities and areas with shorter area codes usually allow for the distribution of more phone numbers due to the longer local number part. Local customer numbers range in length from four to eight digits. Ten or, very rarely, nine digits make up the whole number (not including the initial zero). In the UK, the term “area code” is also used to refer to an “STD (code)” or a “dialing code.”

(020) for London is the area code assigned to the most people. The code assigned to the greatest region is (028) for the entirety of Northern Ireland. Even though Guernsey, Jersey, and the Isle of Man are not territories of the UK, they are nonetheless covered by the UK Numbering Plan.

UK phone numbers have two components. These are, specifically, the UK phone code representing a specific area and the UK phone number. Before dialing the United Kingdom phone number, someone in another location must first dial the UK phone code. Further, we have listed some of the most used UK phone codes.

An example of a UK phone number consists of five to eight numbers to dial, following the UK phone code. Nearly all UK phone numbers are 11 digits long, including the area code. With 10 digits, there are around 40 area codes. Below are some more examples of codes for calling the UK.

Therefore, UK phone codes can be 3 digits with local phone numbers that are 8 digits long, such as 020 numbers for London, 4 digits with phone numbers that are 7 digits long, or 5 digits with phone numbers that are 6 digits long, or, as was indicated before, occasionally 5 digits long. Below are examples of each kind.

For easier readability, it is recommended to display the UK phone code first, followed by a space, and then the remaining portion of the number, for example, 01332 412251 or 01423 396979. In rare cases, adding a separator to the local portion of the number, such as 01332 412 251, might be helpful.

Additionally, it is a good idea to learn an international manner of codes for calling the UK if you are conducting business outside the UK. An example of a UK phone number calling from abroad is +44 1332 412251.

Since 2001, nearly all geographic and non-geographic UK phone numbers have nine or ten significant digits after the beginning “0.” According to E.164, significant numbers are composed of the subscriber number (SN) and the national destination code (NDC). Following the starting “0,” UK mobile phone numbers always include 10 significant digits.

UK Phone Codes with Two-Digits

Two-digit area codes always start with 02 and always have eight-digit subscriber numbers. The most recent geographic number format is this one. It was created as part of the Big Number Change in 2000 and is used for Northern Ireland and the third-tier major cities. The new UK phone code, which starts with 02 instead of the earlier 01, is considerably shorter than the old one. Numbers in these five locations are frequently misspelled, for example, Cardiff as 02920 or London as 0207. The numbers are in the 2+8 format, which consists of an eight-digit subscriber number plus a two-digit UK phone code that follows the pattern 02x.

The local number’s first four numbers designate a specific locality within the town or city. The subscriber component of the number was changed at that time to include an extra digit in London, two or three more digits in Northern Ireland, and two additional digits in all other regions. All of these places were previously subject to a coding change that, as part of PhONEday in 1995, placed a “1” right after the first zero.

(024) Coventry(028) Northern Ireland
(029) Cardiff(023) Southampton
(023) Portsmouth(020) London

UK Phone Codes with Three-Digits

Three-digit UK phone codes always start with 011x or 01×1, and they always contain seven-digit subscriber numbers. The initial batch of five major cities switched to all-figure dialing in the 1960s utilized this format for their geographic numbers. From the 1980s on, Tyne and Wear’s metropolitan county, eastern County Durham, and south-eastern Northumberland also adopted it. The 3+7 format, used in these six locations, consists of a seven-digit subscriber number plus a three-digit area code that follows the pattern 1×1 (after the initial zero). As part of PhONEday in 1995, these UK phone codes were modified by inserting a “1” following the first zero.

(0113) Leeds(0118) Bristol
(0114) Sheffield(0121) Birmingham
(0115) Nottingham(0131) Edinburgh
(0116) Leicester(0141) Glasgow
(0117) Bristol(0151) Liverpool

UK Phone Codes with Four-Digits

Six-digit subscriber numbers or a combination of five- and six-digit subscriber numbers are the norms for four-digit area codes. The majority of places employ this format. It is referred to as the 4+6 format and has a six-digit subscriber number and a four-digit area code (after the initial zero). As part of PhONEday in 1995, these UK phone codes were modified by inserting a “1” following the first zero. This format is used in little under 581 regions, and the area codes used to span from 01200 to 01998. Nearly all (01xxx) area codes currently only have subscriber numbers that are six digits long, although, in a small percentage of these locations, some subscriber numbers are just five digits long (see next section).

Since they share those four digits with the twelve five-digit area codes, six of the four-digit area codes are referred to as “mixed” regions. This results in a restriction on the initial digits that can be used for subscriber numbers within those four-digit area codes. For example, subscriber numbers in the 01387 four-digit area code cannot start with a 3 because 013873 is a separate five-digit area code, and similarly, subscriber numbers in the 01946 four-digit area code cannot start with a 7 because 019467 is a separate five-digit area code.

(01224) Aberdeen(01244) Chester
(01382) Dundee(01387) Dumfries
(01452) Gloucester(01472) Grimsby
(01473) Ipswich(01429) Hartlepool
(01482) Hull(01582) Luton
(01670) Morpeth(01736) Penzance
(01772) Preston(01793) Swindon

UK Phone Codes with Five-Digits

Subscriber numbers with five-digit area codes might be all five digits long or a combination of four and five digits long. Area codes with five and four digits always have the same first four digits.

The twelve smaller towns and villages where the subscriber number is five or (in one area code) four digits long utilize this earliest geographic number type. These formats go by the names 5+5 and 5+4. As a result, following the first zero trunk code, the UK phone code and UK phone number may not always equal 10 digits. As part of PhONEday in 1995, these area codes were modified by inserting a “1” following the first zero. Since these two forms are no longer widely used, Brampton is the final city in the UK to use four-digit local numbers.

(013873) Langholm(015242) Hornby
(015394) Hawkshead(015395) Grange-over-Sands
(016973) Wigton(016974) Raughton Head
(017683) Appleby(017684) Pooley Bridge
(017687) Keswick(019467) Gosforth

How to Call the UK from the US

To call the UK, you will only need to do a few easy steps.

  • Step 1. Dial the exit code or international access code (011)

First, dial 011 to place an international call to the UK from the US. This exit code indicates that the call you are placing is from outside the US. Alternatively, if you are using a mobile phone, you might need to change 011 to the “+” key. You may need to press this particular key on some cell phones.

  • Step 2. Enter the country code (44)

Next, dial an international code to call the UK, which is 44. Any UK phone number may be reached by entering the country code.

  • Step 3. Enter the UK phone code

The area code for the region you’re attempting to reach must be dialed in order to call the UK from the US. Keep in mind that UK phone codes might range from two to five digits. Don’t dial this digit if the area code starts with a 0 in it. Only enter the numbers that come after.

  • Step 4. Dial the UK phone number

The remaining part of the phone number can be inserted after the UK phone code. The total phone number should be 10 digits long, including the area code.

An example of a UK phone number might be 011-44-117-1234-555.

By following these procedures, you should be able to call any active landline in the UK from the United States.

You must display the number in the international format if you need callers from outside of the UK to call you.

The international dialing code is 00 in the United Kingdom and much of Europe. Since it varies globally, the customary practice is to utilize + in place of the international dialing code and let the caller provide their own code as necessary.

The code for calling the UK is 44. Additionally, calling into the UK from outside of the nation does not require dialing the starting zero; this is shown by a bracket. For instance, 01382 649350 for Dundee or +44 (0) 01382 649350.

You must first call the International Direct Dialing (IDD) number before dialing out to another nation. Other nations may use several IDDs or use different digits from the UK’s 00.

Then you will want the Country Code, which is ordinarily unique to each nation but is shared by the US, Canada, and the Caribbean.

Emergency Services

Only the Police may be reached at 101 in a non-emergency. Only calls from within England, Wales, Scotland, or Northern Ireland are eligible for the 101 number.

A relatively recent phone number to call the NHS is 111. When you urgently need medical attention or guidance but can’t wait for a doctor’s appointment, you should dial this number.

In the UK, 112 debuted in 1995. It was implemented throughout Europe to provide a uniform and standardized number for anybody traveling inside the EU. Calls operate in the exact same manner and route to the exact same services as 999. The crucial aspect of 112 is that it is mobile phone compatible anywhere in the world.

It has been requested that 119 UK network operators develop a new national dialing code, which is 119. As a component of the NHS COVID-19 response, it will be deployed. By handling COVID-19-specific situations, it will relieve some of the burdens on the 111 NHS Direct service.
