Navigating international dialing codes can often seem a daunting task, especially when you’re trying to get in touch with friends, family, or business associates residing across the pond. But with a little understanding of the process, placing a call from the United Kingdom to the United States can be as straightforward as dialing a local number. In this blog, we’re going to demystify this process and provide a step-by-step guide on how to call the US from the UK. Whether it’s for personal or professional purposes, we’ve got you covered. So let’s dive in!
1. Understanding the Basics

Concept Of Country Codes And International Exit Codes
Before we go further, it’s essential to understand the basics of country codes and international exit codes. An international exit code, also known as an International Direct Dial (IDD) code, is a number used to dial out of a country. Each country has its own unique IDD code. In the case of the UK, as we’ve seen, this code is 00.
On the other hand, a country code is a numerical prefix that you dial when you’re calling to a different country. Every country has its unique country code. For instance, the country code for the United States is 1.
When making an international call, these two codes are dialed first, followed by the specific area code and local number of the person you’re trying to reach. It’s a systematic process designed to make international dialing consistent and easier to manage.
Specific Codes for the UK and the US
The specific codes for the UK and the US are vital in making international calls. As mentioned earlier, the International Direct Dial (IDD) code for the UK is 00. This is the number that you’ll use to dial out of the UK. The country code for the United States, on the other hand, is 1. This code is dialed after the IDD to reach the US from another country. Therefore, when making a call from the UK to the US, your dialing sequence will start with 00 (the IDD for the UK), followed by 1 (the country code for the US), and then the specific area code and local number.
2. Step-by-step Guide
Step 1: Dial the International Direct Dial (IDD) Code
The first step in making an international call is to dial the International Direct Dial (IDD) code. For the UK, this code is 00.
Step 2: Dial the Country Code
Next, dial the Country Code for the United States, which is 1.
Step 3: Dial the Area Code
The US is divided into numerous area codes. Dial the specific area code for the region you are trying to reach. For instance, the area code for New York City is 212 or 718.
Step 4: Dial the Local Number
Finally, you’ll dial the local telephone number you’re trying to reach. This is typically a seven-digit number.
So, if you’re calling a New York City number 123-4567, the complete dialing sequence would look like this: 00-1-212-1234567. And there you have it—a straightforward guide to calling the US from the UK!

3. Handling Special Cases
There are some unique scenarios you might encounter when calling the US from the UK, such as dialing US toll-free numbers. These numbers typically start with 800 or 888 and are often used by businesses for customer service lines. However, calling a toll-free number from outside the United States is not the same as calling a regular US number.

In many cases, US toll-free numbers are not accessible from overseas, or they may incur regular international calling charges, negating the “toll-free” aspect. If you find yourself needing to call a US toll-free number from the UK, it’s advisable to first check with the organization to confirm whether their toll-free number can be dialed internationally, and if so, what the applicable charges will be. Alternatively, many companies provide alternative regular (non-toll-free) numbers for their international customers.
If you want to avoid potential costs, consider using an internet-based calling service like Skype, Google Voice, or a VOIP service, which may offer reduced rates or even free calls to certain toll-free numbers. Just remember to check the rates with your chosen service before dialing.
4. Using Alternatives
In the digital age, Voice over Internet Protocol (VoIP) services have emerged as a cost-effective alternative to traditional calling methods, especially for international communication. VoIP services, such as Skype, Zoom, or WhatsApp, allow you to make calls using an internet connection rather than a regular phone line, often at reduced rates or even for free.

VoIP services offer the same functionality as a regular phone call, allowing you to dial US numbers directly – whether they’re landline or mobile numbers. The call quality is typically comparable to regular calls, although it can be affected by the quality of your internet connection.
Most VoIP services also offer additional features such as video calling, instant messaging, and file sharing, making them a versatile tool for both personal and business communication. However, it’s important to note that VoIP services may not offer emergency service calling in all areas, so a standard phone connection may still be necessary for these situations.
For calling the US from the UK, exploring VoIP services can be a beneficial approach. Just remember to check the terms of service and any associated costs before making a call.
Conclusion
In conclusion, the different methods of calling the US from the UK, whether it’s through traditional dialing codes, internet-based calling services, or VoIP services, each has its own benefits. The key is to weigh these options against your specific needs and resources. Do remember to always check the rates and terms of service before making your call. While the digital age has made international communication easier and more affordable, it’s important to maintain a traditional phone connection for emergencies. Happy dialing!
