What Is the UK Country Code?

A country calling code helps you connect with people in other countries. You use this code when you make an international call. The country code for the UK is a unique number that lets phone networks know you want to reach someone in the United Kingdom.

• Each country or region has its own country code.
• You dial the international country code after the exit code of your country.
• The country code for the UK is 44.
• You only use the country code for the UK when calling from outside the UK.

How to Call the UK

Learning how to call the UK is important if you want to reach friends, family, or businesses in the United Kingdom. You need to follow the correct international calling format to make sure your call connects. This section will guide you through each step and show you the differences between calling a UK landline and a UK mobile number.

Dialing Steps

You can follow these steps to call the UK from the United States or any other country. The process uses the international country code and follows a standard international calling format.

1. Dial the exit code for your country. If you are in the United States, the exit code is 011. This code tells your phone provider that you want to make an international call.
2. Enter the international country code for the United Kingdom, which is 44.
3. If you are calling a UK landline, dial the area code without the leading zero. UK area codes can have two to five digits.
4. If you are calling a UK mobile number, dial the mobile prefix without the leading zero. UK mobile numbers always start with ‘7’ after you remove the zero.
5. Dial the rest of the local phone number.

Tip: On most cell phones, you can hold down the ‘0’ key until a ‘+’ appears. The plus sign replaces the exit code, so you can dial +44 instead of 011 44.

Here is a quick summary table to help you understand the difference between calling a UK landline and a UK mobile number:

You always drop the first zero from the area code or mobile prefix when using the international calling format.

Example: Calling the UK from the US

Let’s look at two examples to show you exactly how to call the UK. These examples use the correct international calling format and show you how to handle both landline and mobile numbers.

Example 1: Calling a UK Landline

Suppose you want to call a friend in Glasgow. The local number is 8765 432, and the area code for Glasgow is 0141. Here is how to call:

1. Dial the US exit code: 011
2. Dial the UK country code: 44
3. Dial the area code without the leading zero: 141
4. Dial the local number: 8765 432

So, you would dial:
011 44 141 8765 432

Example 2: Calling a UK Mobile Number

Now, let’s say you want to call a UK mobile number: 07700 900123. Here is how to call the UK mobile:

• Dial the US exit code: 011
• Dial the UK country code: 44
• Dial the mobile number without the leading zero: 7700 900123

So, you would dial:
011 44 7700 900123

Note: UK mobile numbers always start with ‘07’ when dialed inside the UK. When you use the international calling format, you drop the ‘0’ and start with ‘7’.

If you use a US cell phone, you can also dial:
+44 7700 900123

This method works for both landlines and mobiles. You just need to remember to remove the first zero from the area code or mobile prefix.

If you want to know how to call the UK from other countries, you only need to change the exit code. The rest of the steps stay the same. Always use the international country code and follow the international calling format.

Remember: If you want to know how to call the UK, always check the number for the correct format. Dropping the initial zero is the most common mistake people make.

If you follow these steps, you will know exactly how to call the UK, whether you are dialing a landline or a mobile number. Understanding how to call the UK will help you avoid mistakes and make sure your call goes through.

UK Area Codes and Prefixes

Major City Area Codes

You will find that uk area codes help you reach the right city or region when you call the United Kingdom. Each city has its own code, and larger cities use shorter codes to handle more calls. London, for example, uses the area code 020. Manchester uses 0161. These shorter codes make it easier for you to remember and dial numbers in busy cities. Here is a table of major city area codes:

You can see that uk area codes range from two to five digits. Shorter codes are common in cities with more people and higher call volumes.

Mobile Number Prefixes

When you look at a uk phone number, you can tell if it is a mobile number by its prefix. UK mobile numbers always start with ‘07’ when you dial them inside the UK. If you call from another country, you drop the first ‘0’ and use the country code +44. For example, the number 07700 900123 becomes +44 7700 900123 when dialed internationally. This change helps your call reach the right mobile network.

• UK mobile numbers start with ‘07’
• Replace the ‘0’ with +44 for international calls
• Example: 07911 123456 becomes +44 7911 123456

If you forget to drop the ‘0’, your call may not go through.

Trunk Code Usage

The trunk code ‘0’ plays a key role in the dialling code in the uk. You use this ‘0’ only when you call within the United Kingdom. When you call from outside the UK, you must leave out the ‘0’ and use the country code +44 instead. For example, if you see a number written as 020 7946 0321, you dial +44 20 7946 0321 from abroad. This rule applies to both landlines and mobile numbers. Always check the format before you dial to avoid mistakes.

Troubleshooting and Tips

Common Dialing Mistakes

You may face problems when calling the United Kingdom if you make small errors in the dialing process. Here are some mistakes that people often make:

• Forgetting to drop the leading zero from the UK area code or mobile number when dialing internationally.
• Using the wrong country code or exit code.
• Adding spaces, dashes, or parentheses in the number, which can confuse some phone systems.
• Dialing the number at an inconvenient time for the person in the UK.
• Not checking if the number is active or valid before calling.

Tip: Always format the number according to the E.164 standard. Remove the leading zero and use +44. For example, 020 7123 4567 becomes +44 20 7123 4567.

If Your Call Fails

If your call does not go through, you can try these steps:

1. Double-check the dialing sequence. Make sure you start with the exit code (such as 011 from the US), then add +44, followed by the area code (without the zero) and the local number.
2. Confirm that you have removed the leading zero from the UK number.
3. Check your phone connection or internet if you use VoIP services.
4. Use a reliable online tool to verify the UK phone number. Many tools can check if the number is active, identify the type of line, and provide carrier information.

Note: If you still cannot connect, try calling at a different time or contact your service provider for help.
