To dial a UK number from the USA, call 011 + 44 + area code (without 0) + local number.
If you type how do i dial a uk number from usa? into a search box, you are usually sitting with a phone in your hand and a UK hotel, tour operator, or friend waiting on the other end. The good news is that once you know what each block of digits means, calling the United Kingdom from the United States feels as routine as any domestic call. This guide walks through the exact sequence, shows clear examples, and flags common mistakes that cause failed calls or surprise charges.
How Do I Dial A UK Number From USA? Step-By-Step Example
Every successful call from the USA to the UK follows the same pattern:
- Exit code from the USA
- UK country code
- UK area or mobile code (without the leading 0)
- Local subscriber number
Basic Five-Step Sequence
Here is the standard five-step process that answers the question, How Do I Dial A UK Number From USA?, in practical terms:
- Dial 011 on a US landline or mobile, or press and hold + on many mobiles.
- Dial 44, which is the country code for the United Kingdom.
- Drop the leading 0 from the UK number’s area or mobile code.
- Dial the area or mobile code without that 0.
- Dial the rest of the local number exactly as shown.
Worked London Number Example
Say your London hotel writes its contact as 020 7946 0958 on the booking. From inside the UK, callers dial all those digits. From the USA, you would dial:
011 44 20 7946 0958
In this example, 011 is the US exit code, 44 is the UK country code, 20 is the London area code without its 0, and the rest is the local number. The same logic works for other cities and for UK mobiles, with only the middle section changing.
Basic Dialing Formats For UK Numbers From The USA
The structure stays the same, but the middle digits change with the type of UK number you call. The table below gives a quick reference for common cases.
| Type Of UK Number | Local UK Format | Dial From USA |
|---|---|---|
| Standard Landline (London) | 020 7946 0958 | 011 44 20 7946 0958 |
| Standard Landline (Manchester) | 0161 234 5678 | 011 44 161 234 5678 |
| UK Mobile Number | 07123 456789 | 011 44 7123 456789 |
| Non-Geographic 03 Number | 0330 123 4567 | 011 44 330 123 4567 |
| Freephone 0800 Number | 0800 111 1111 | 011 44 800 111 1111 |
| Business 084 Or 087 Number | 0845 123 4567 | 011 44 845 123 4567 |
| Premium 09 Number | 0901 234 5678 | 011 44 901 234 5678 |
Notice how the leading 0 drops away in every international format. Keeping that 0 is one of the most common reasons calls fail from the United States.
Dialing A UK Number From USA: What The Digits Mean
The sequence 011-44-area-number can feel abstract until you know what each part represents. Once that clicks, any UK number on a booking confirmation or ticket becomes easy to convert.
Exit Code 011 Or The Plus Sign
When you call from the United States to any other country, you start with the international access code. On US networks this is 011, as described in the
FCC international calling tip sheet.
On many mobile phones you can press and hold the 0 key until a + symbol appears. That plus sign tells the network to insert the exit code for your location, so +44 and 011 44 reach the same destination when you call from the USA.
UK Country Code 44
Every country on the global phone system has at least one country code, and the UK’s is 44. That code covers England, Scotland, Wales, Northern Ireland, and several nearby islands under the UK numbering plan. Once you have dialed 011 or +, the digits 44 tell the network to route your call to that system and hand the rest of the digits to UK exchanges.
Dropping The UK Trunk Code 0
Inside the UK, callers usually start with a 0 before the area code or mobile code. That 0 is a domestic trunk code, not part of the true international number. When you dial from the USA, you remove that 0.
The UK regulator Ofcom explains this pattern in its numbering information and provides an
Ofcom area code finder
that shows valid landline codes.
So a UK mobile written as 07123 456789 becomes 011 44 7123 456789 from the United States, and a Cardiff landline 029 2040 1234 becomes 011 44 29 2040 1234.
Landlines, Mobiles, And Special UK Number Ranges
Not every UK number behaves the same way once you call from abroad. The starting digits tell you what you are dealing with and hint at possible costs.
01 And 02 Numbers: Geographic Landlines
Numbers beginning with 01 or 02 are ordinary landlines tied to specific towns and cities. London uses 020, Manchester uses 0161, and many other cities use their own codes. From the USA you remove the leading 0 and place 44 in front of the rest. These lines often carry lower per-minute rates than mobile or premium ranges, so they are common for hotels, guesthouses, and offices.
07 Numbers: Mobiles And Personal Numbers
Most mobile phones in the UK start with 07. When you dial from the USA, you change 07 to 7 after the country code, as in 011 44 7xxx xxxxxx. Mobile rates from the United States sometimes differ from landline rates, even if the person you are calling is standing in a hotel lobby, so it is worth checking whether you are ringing a mobile or a fixed line.
03 Numbers: National Rate Contacts
Many banks, airlines, and customer service lines use 03 numbers. The caller inside the UK pays the same as a normal landline call. From the USA, though, an 03 number behaves much like any other national UK number. You still apply the 011-44 format and you still drop the leading 0, turning 0330 123 4567 into 011 44 330 123 4567.
08 And 09 Numbers: Freephone And Premium Services
Numbers beginning 0800 are free for callers inside the UK, yet they may not be free, or even reachable, from outside the country. Other 08 ranges and 09 ranges can carry high per-minute charges when dialed internationally. When a UK business offers both a geographic number and an 08 or 09 line, the geographic option is usually the safer choice from America in both cost and reliability terms.
Costs And Time Zones When Calling The UK From America
Getting the digits right answers how do i dial a uk number from usa?, but the timing and price also matter for travelers and callers with family overseas.
Checking The Price Before You Dial
International rates vary widely between carriers and even between landline, post-paid mobile, and prepaid mobile plans. Some providers sell international add-on packages that reduce the rate to the UK, while others charge a flat amount per call plus a per-minute fee. The
FCC basic rate guidance
encourages callers to compare these charges with internet-based options such as calling apps. A quick visit to your carrier’s website or app before a long call can trim your bill, especially when you expect an hour or more on the line.
Local Time In The UK
The United Kingdom runs on Greenwich Mean Time (GMT) in winter and British Summer Time (BST, GMT+1) in summer. The time gap between the US and the UK depends on your own time zone and on daylight saving changes. From the US East Coast, the UK is usually five hours ahead in winter and often still five hours ahead in summer, while from the West Coast the offset is normally eight hours.
Before you dial a UK number from the USA, glance at a world clock on your phone. Midday in New York means evening in London, and late afternoon in Los Angeles can mean the middle of the night in Scotland. Planning around that gap avoids waking a front desk or missing a business office window.
App, Wi-Fi, And VoIP Options For UK Calls
Traditional dialing is not the only way to reach the UK. If you have a solid Wi-Fi connection, calling apps and VoIP services can route your voice through the internet instead of a regular voice channel.
Calling Through Messaging Apps
Many popular messaging apps allow voice and video calls between users at no extra charge beyond data usage. When both you and the person in the UK have the same app, tapping the call button can be easier than entering an international format. This works well for friends and family and for hosts who share their contact through an app.
App-To-Phone Services
Some services let you call a regular UK phone number from your smartphone through an app. You still dial the full international format inside the app, but the provider may charge lower rates than your mobile carrier. This approach is handy when your hotel Wi-Fi is strong and your mobile plan charges high international voice rates.
Wi-Fi Calling From Your Mobile Carrier
Many US mobile carriers support Wi-Fi calling, where your normal phone app routes calls over the internet while you are connected to Wi-Fi. In some cases the rates for Wi-Fi calls to the UK differ from standard cellular rates. Check your carrier’s Wi-Fi calling page before a trip so you know whether those calls count as standard minutes, special international minutes, or a separate charge.
Dialing Examples For Major UK Cities From The USA
Once you understand the pattern, you can convert any printed UK number into a US-friendly format. These examples show common city codes and how they change when you call across the Atlantic.
| City Or Region | Local UK Number Format | Dial From USA |
|---|---|---|

| Manchester | 0161 234 5678 | 011 44 161 234 5678 |
| Edinburgh | 0131 987 6543 | 011 44 131 987 6543 |
| Cardiff | 029 2040 1234 | 011 44 29 2040 1234 |
| Birmingham | 0121 345 6789 | 011 44 121 345 6789 |
| Belfast | 028 9012 3456 | 011 44 28 9012 3456 |
| UK Mobile | 07123 456789 | 011 44 7123 456789 |
City codes change, but the rule does not: swap 0 for 44 and keep the rest of the digits in the same order. With this table as a mental template, any unfamiliar UK code on your itinerary becomes easy to handle.
