Ever tried calling a friend in London only to be met with a confusing silence or, worse, a wrong number? Connecting with the UK from the US might seem straightforward, but the nuances of international dialing codes can quickly turn a simple phone call into a frustrating experience. With so many personal and professional connections spanning the Atlantic, knowing the precise steps for a successful call is more important than ever.
Whether you’re checking in with family, finalizing a business deal, or simply sharing exciting news, a reliable and efficient way to call London is essential. Navigating time differences, country codes, and area codes can be tricky, and a misstep can lead to wasted time and unnecessary charges. This guide will demystify the process, ensuring you can easily reach your contacts across the pond without any hassle.
What exactly are the steps to call London from the US?
What’s the dialing code for London from the US?
To call London from the US, you need to dial 011 (the US exit code), then 44 (the UK country code), and then the London area code (20) followed by the eight-digit local London phone number. So the full format is: 011-44-20-XXXXXXXX.
Calling internationally can seem daunting, but breaking it down into steps makes it straightforward. First, you dial 011, which is the exit code needed to dial out of the United States. This tells your phone company that you are making an international call. Then, you need the country code for the United Kingdom, which is 44. Every country has its own unique code. After the country code, you dial the area code. London’s area code is 20. It’s important to always include the area code, even when calling from within the UK but outside of London. Finally, you dial the eight-digit local London phone number assigned to the person or business you are trying to reach. Leaving out any of these components will likely result in a failed call.
Do I need to dial an exit code from the US?
Yes, when calling London or any international number from the US, you absolutely need to dial the US exit code (also called an international access code) before dialing the country code for the UK and the London area code and local number. This exit code signals to your phone carrier that you’re making an international call.
When dialing internationally from the US, the exit code you’ll use is “011.” This is followed by the UK country code (44), the London area code (20), and then the eight-digit local number. For example, a London number would be dialed as 011-44-20-xxxxxxxx. Forgetting the exit code will result in your call not connecting, or potentially being misrouted as a domestic US number, and generating an error message. Be sure to verify you’re dialing the correct exit code, especially if you are using a mobile phone. While mobile phones often automatically detect international dialing from your contacts, manually dialing the number without the exit code will likely result in a failed call. Always double check that you have correctly entered all the digits including 011, 44, and 20.
How do I account for time differences when calling?
To account for time differences when calling London from the US, you need to know the current time difference between the specific location in the US you’re calling from and London. London operates on Greenwich Mean Time (GMT) during standard time and British Summer Time (BST) during daylight saving time, which typically runs from late March to late October. The US has multiple time zones, so the difference can range from 5 to 8 hours. To avoid calling at inconvenient times, convert the current time in your location to London time before placing your call.
The most straightforward approach is to use online time zone converters or world clocks. These tools allow you to input your current location and instantly see the corresponding time in London. Remember to factor in whether both locations are currently observing daylight saving time/BST. Daylight saving time adjustments can shift the time difference by an hour. Consider what time of day is appropriate to call. For example, avoid calling London during their late-night hours (roughly 11 PM to 7 AM GMT/BST). A good rule of thumb is to aim for calls during London’s business hours (9 AM to 5 PM GMT/BST), which would translate to early morning hours in the US, depending on your specific time zone. Early morning calls (before 9 AM) in the US ensure you reach London during their active business hours.
What’s the format for a London phone number?
London phone numbers typically follow the UK format: 020 followed by an 8-digit local number. This means a complete London number will look like 020 xxxx xxxx.
When calling London from the US, you must first dial the US exit code 011, then the UK country code 44, then the London area code 20 (dropping the leading 0), and finally the 8-digit local number. So, the full dialing sequence from the US becomes 011 44 20 xxxx xxxx. Failing to include the correct codes or omitting the leading zero from the London area code after dialing the country code will result in the call not connecting. For example, if the London number is 020 7946 0000, you would dial 011 44 20 7946 0000 from the US. Remember that international call charges apply, so check with your phone provider for rates before making the call. Many mobile phone plans now offer international calling packages or reduced rates, which can significantly lower the cost of calling London.
Does it matter if I’m calling a mobile or landline?
No, it typically doesn’t matter if you’re calling a mobile or landline in London from the US in terms of the dialing code sequence you need to use. The same international dialing code, country code, and area code (if required) applies regardless of the recipient’s device type.
The only difference you *might* encounter, although increasingly rare, is in the cost of the call depending on your phone plan and the provider being used. Historically, some providers charged slightly different rates for calls to mobile phones versus landlines internationally. However, most modern plans offer bundled international minutes or fixed-rate international calling, often making this distinction irrelevant. It’s always a good idea to check with your phone service provider for their specific rates and policies for international calls to the UK.
Therefore, focus on dialing the correct sequence: 011 (US exit code) + 44 (UK country code) + London area code (if applicable, usually 20) + the local number. Ensure you’ve dialed correctly and consider using a calling app or VoIP service if you’re looking for cheaper options, regardless of whether you’re calling a mobile or landline.
How do I call a UK toll-free number from the US?
Calling a UK toll-free number (starting with 0800, 0808, or sometimes 0500) from the US requires you to dial a specific international access code, the UK country code, and then replace the initial ‘0’ of the toll-free number with ‘44’. So, the general format is: 011 + 44 + (UK toll-free number without the initial ‘0’).
Specifically, the ‘011’ is the US exit code needed to dial internationally. ‘44’ is the country code for the United Kingdom. Then, you take the UK toll-free number (for example, 0800 123 4567) and drop the initial ‘0’, replacing it with the country code. Therefore, the number you would dial from the US in our example would be 011 44 800 123 4567. This applies whether you are using a landline, a cell phone, or a VoIP service.
Keep in mind that while these numbers are “toll-free” *within* the UK, you might still incur charges from your US phone provider for making an international call. It is advisable to check with your phone company regarding their international calling rates or if they offer any international calling plans to potentially save money. Some VoIP services may offer more competitive rates for international calls than traditional phone companies.
