How to call the UK from the US

International calling
Get Started

With the latest advancements in technology, it is easier than ever to communicate with anyone from practically anywhere in the world. But, calling the UK from the US can be challenging and expensive. In this article, we’re sharing the different ways you can call someone in the UK from the US, along with comparisons of different methods and services.

How to call the UK from the US

If you’re calling the UK from the United States, here’s what you need to do:

  • Dial the country exit code (US)

Before calling a UK phone number, dial 011, which is the US country exit code.

  • Dial the UK country code

After dialing 011, dial the UK country code, which is 44. That’s 011 + 44.

  • Dial the area code

UK area codes can range from two to five digits. For international calls, remember to remove the zero (0) from the area code, so, if, for instance, the area code of the city you’re connecting to is 029, you’ll be dialing 29 instead of 029. That’s 011 + 44 + 29.

  • Dial the phone number of the person you’re calling

Once you’ve done the first three steps, you can proceed to dial the phone number of the other person. Note that UK phone numbers should have a total of 10 digits, including the area code.

So, If you’re calling a number in Cardiff, for example, which has an area code of 029, the number you’ll dial would look like this: 011-44-29-XXXX-XXXX.

If you are calling the UK from a US Cellphone

To call from the US to the United Kingdom using a US cellphone, you only need to follow the above-mentioned steps, except for dialing the area code. Today’s smartphones offer a shortcut when it comes to dialing international numbers.

Instead of manually dialing the international exit code (011), simply press and hold the zero (0) button on the dial pad until you see the + sign appear. You can then proceed to dial the remaining digits, which include the country code, area code, and phone number.

Moreover, you need to take note of the mobile code for the UK, which is 7. So you’ll be dialing 011-44-7-xxx-xxx-xxx.

Calling the UK from Landlines

If you’re calling the UK using a landline, follow all the previously mentioned steps: dial the US exit code, the UK country code, the area code for the location you’re calling, and the phone number of the other person.

Here’s a bonus question: Does it cost extra to call the UK?

This depends on several factors.

If you’re not enrolled in an international calling plan, you’ll be subject to basic rates, which are essentially just non-discounted rates for international calls. If you don’t regularly make international calls, this is a cost-effective option for you.

But, if you’re frequently making calls to the UK, you might consider signing up for an international calling plan for discounted fees. These plans usually include a 300-minute limit, and you may be charged additionally per minute when you exceed the respective limit set by your provider.

UK area codes

If you’re making calls from the US to the UK, you need to know the area code of the person you’re calling. Below are some of the most popular area codes for when you’re calling the UK.
