Knowing how to call UK from US is important when contacting friends, family, or businesses in the United Kingdom. International calls require the correct dialing format, including the exit code, country code, and local phone number.
This guide explains the UK country code, the correct dialing structure, and simple steps that help ensure your call connects successfully from the United States.
1. What You Need to Call the UK from the US
Before dialing an international number, it helps to understand how to call UK from US and the information required to complete the call successfully. International dialing works slightly differently from domestic calls because the phone system must identify the destination country and route the call through the global network.
First, you need the international access code used in the United States, which is 011. This code tells the phone network that you are making an international call rather than a domestic one.
Second, you need the country code for the United Kingdom. Each country has its own code that directs the call to the correct national network.
Third, you should have the area code and the local phone number of the person or business you are trying to reach. UK phone numbers are usually written with a leading zero for domestic calls, but this zero is typically removed when dialing from outside the country.
Finally, a mobile phone or landline with international calling enabled is required. Some mobile plans support international calling features, which makes it easier to contact numbers in other countries without needing additional apps or calling services.
2. UK Country Code and Dialing Format
Understanding the correct dialing structure is an important part of learning how to dial UK from US. International calls follow a specific order of numbers that allows the phone network to connect your call to the correct country and region.
UK Country Code
The country code for the United Kingdom is +44. This number tells the global phone network that the call should be routed to the UK.
When dialing from the United States, the country code is entered after the international access code. The plus sign (+) often appears when numbers are written internationally, but when dialing from the US you typically replace the plus sign with the international prefix 011.
Full Dialing Format from the US
The standard dialing format for calling the United Kingdom from the United States looks like this: 011 + 44 + area code + local phone number
For example, if you want to call a London number written locally as: 020 1234 5678
You would dial it from the United States as: 011 44 20 1234 5678
Notice that the leading zero in the UK area code is removed when dialing internationally. Following the correct dialing format helps ensure the call connects properly to the destination number in the United Kingdom.
3. Step-by-Step: How to Call UK from US
Once you understand the dialing format, learning how to call the UK from the US becomes straightforward. International calls follow a sequence that directs the phone network from the United States to the United Kingdom and then to the correct local number.
Step 1: Dial the International Access Code
Start by dialing 011, which is the international access code used in the United States. This number tells your phone carrier that you are placing a call outside the country.
Without dialing this code first, the phone system will treat the number as a domestic call and the call will not connect internationally.
Step 2: Enter the UK Country Code
Next, dial the UK country code, which is 44. This code routes the call to the United Kingdom’s telephone network.
At this point, the number you dial will begin to follow the international structure used for global calls.
Step 3: Dial the Area Code
After entering the country code, dial the UK area code for the city or region you are calling. UK phone numbers normally include a leading zero when dialed domestically, but this zero should be removed when dialing from another country.
For example:
- London area code: 020 → dial 20
- Manchester area code: 0161 → dial 161
Removing the leading zero is an important step when learning how to call UK from US.
Step 4: Enter the Local Phone Number
Finally, dial the local phone number of the person or business you are calling.
The full dialing format will look like this:
011 + 44 + area code (without the leading 0) + local phone number
Following this format ensures your call is correctly routed from the United States to the UK.
4. Common Mistakes When Calling the UK
Even when people know the basic dialing format, small mistakes can still prevent the call from connecting. When learning how to call UK from US, avoiding these common errors can help ensure the call goes through successfully.
Forgetting to Remove the Leading Zero
One of the most common mistakes is keeping the leading zero in the UK area code. In the United Kingdom, domestic numbers usually start with a zero, but that zero is not used when dialing internationally.
For example:
UK domestic format: 020 1234 5678
Correct international format from the US: 011 44 20 1234 5678
Keeping the zero can cause the call to fail or connect incorrectly.
Using the Wrong International Prefix
Another frequent mistake is dialing the wrong international access code. Some countries use prefixes such as 00, but the correct international prefix from the United States is 011.
If you dial 00 44 instead of 011 44, the call may not go through depending on your carrier.
Using the correct international access code is a key part of successfully completing the dialing process when calling the United Kingdom from the United States.
