Calling a UK landline from abroad takes exactly four pieces of information: your exit code, the UK country code (44), the area code, and the local number. Get the sequence right, and your call connects in seconds. Get it wrong—usually by leaving in that extra 0—and the call fails before it starts.
This guide covers the exact dialing format from any country, UK area codes for major cities, what to do about toll-free numbers, and how to cut your per-minute costs by up to 90%.
How to dial a UK landline from abroad
Here's the quick version: dial your exit code (or just +), then 44, then the UK number without the leading 0. A London number like 020 7946 0123 becomes +44 20 7946 0123 when you're calling from outside the UK.
That's the universal format. It works whether you're calling from New York, Sydney, Berlin, or anywhere else—the only thing that changes is your country's exit code.
Step 1. Dial your country exit code
The exit code signals to your phone carrier that you're making an international call. Think of it as the "unlock" that lets your call leave your country's phone network.
From the US or Canada, that code is 011. From most of Europe and Australia, it's 00 or 0011. Here's the good news: on any mobile phone, you can skip memorizing exit codes entirely and just dial + instead. Your phone handles the rest.
Step 2. Dial the UK country code 44
After the exit code comes 44—the country code that routes your call to the United Kingdom. Every country has one of these codes, and the UK's is always 44.
You'll often see UK numbers written as +44 20 7946 0123. That +44 is doing the same job as your exit code plus 44.
Step 3. Drop the leading 0 from the UK number
This is where most people trip up. UK phone numbers start with 0 when dialed inside the country, but that 0 disappears when you're calling from abroad.
So if someone gives you 020 7946 0123, you dial +44 20 7946 0123. Not +44 020—just +44 20. Including that extra 0 will cause the call to fail.
Step 4. Dial the area code and local number
UK landlines have a geographic area code built into the number. London is 020, Manchester is 0161, Birmingham is 0121, and so on. After you drop the leading 0, dial the rest of the area code followed by the local number.
Most UK landline numbers have 10 or 11 digits total, including the area code. Use a phone number validator to confirm the format before dialing.
UK landline dialing format examples
| Location | UK domestic format | International format |
|---|---|---|
| London | 020 7946 0123 | +44 20 7946 0123 |
| Manchester | 0161 496 0123 | +44 161 496 0123 |
| Edinburgh | 0131 496 0123 | +44 131 496 0123 |
How to dial United Kingdom from US
From the United States, the format is 011 + 44 + the UK number without the leading 0. A London number like 020 7946 0123 becomes 011 44 20 7946 0123.
Breaking it down:
- 011: The US exit code for international calls
- 44: The UK country code, which replaces the domestic 0
- Area code + number: Everything after the leading 0
On a US mobile phone, dialing +44 works exactly the same as 011 44. Either way gets you connected.
UK country code and exit codes by country
What is the UK country code
The UK country code is +44. You might also see it written as 0044—both mean the same thing. The + symbol is just a universal stand-in for whatever exit code your country uses.
When a UK number appears as +44 20 7946 0123, you can dial it exactly that way from any mobile phone in the world.
Exit codes for calling the UK from different countries
| Country | Exit code | Example dial format |
|---|---|---|
| USA/Canada | 011 | 011 44 20 XXXX XXXX |
| Australia | 0011 | 0011 44 20 XXXX XXXX |
| Germany | 00 | 00 44 20 XXXX XXXX |
| India | 00 | 00 44 20 XXXX XXXX |
| France | 00 | 00 44 20 XXXX XXXX |
On mobile phones, dialing + instead of the exit code works everywhere. Your phone automatically converts it.

UK area codes for major cities
UK landline numbers include a geographic area code that identifies the city or region. Knowing the area code helps confirm you're dialing the right place.
London area codes
London uses 020. In international format, that becomes +44 20 followed by an 8-digit local number.
Manchester and Birmingham area codes
Manchester is 0161, Birmingham is 0121. Internationally, dial +44 161 or +44 121.
Edinburgh and Glasgow area codes
Scotland's largest cities use 0131 (Edinburgh) and 0141 (Glasgow). From abroad, that's +44 131 and +44 141.
Belfast and Cardiff area codes
Belfast in Northern Ireland uses 028, Cardiff in Wales uses 029. Same rule applies—drop the 0, add +44.
| City | UK area code | International format |
|---|---|---|
| London | 020 | +44 20 |
| Manchester | 0161 | +44 161 |
| Birmingham | 0121 | +44 121 |
| Edinburgh | 0131 | +44 131 |
| Glasgow | 0141 | +44 141 |
| Belfast | 028 | +44 28 |
| Cardiff | 029 | +44 29 |
How to call UK toll-free and special numbers from abroad
UK numbers starting with 08 or 09 work differently when you're calling internationally. Some won't connect at all, and others will charge you even though they're free inside the UK.
Calling UK 0800 freephone numbers
UK 0800 numbers are free for callers inside the UK. From abroad, though, most either won't connect or will charge standard international rates.
If you're trying to reach a UK airline, bank, or hotel on their 0800 line, look for an international contact number on their website. Many companies list a geographic landline (starting with 01 or 02) as an alternative.
Calling UK 0845 and 0870 numbers
These service numbers carry higher rates even within the UK, and they often don't work at all from abroad. Your best bet is to search for the organization's geographic landline number instead.
Tip: Search the company name plus "international contact number" to find a dialable alternative.
Why free messaging apps cannot call UK landlines
WhatsApp, iMessage, and similar apps only work when both people have the app installed and internet access. Over 17 million UK landlines don't have apps—they're connected to the traditional phone network, not the internet.
To reach a UK landline, you need a service that bridges your internet connection to the phone network. VoIP calling services do exactly this: you call from your browser or app over Wi-Fi, and the call connects to any regular phone number.
- WhatsApp/iMessage: Only works if the recipient has the app
- UK landlines: Cannot receive internet-based calls
- VoIP services: Connect your internet call to any phone number

How much does it cost to call a UK landline from abroad
Costs vary widely depending on how you call. Traditional carriers often charge $0.50 to $2.00 per minute, while VoIP services can be as low as $0.03 to $0.05 per minute.
Traditional mobile carrier rates
Calling UK landlines through your mobile carrier typically runs $0.50 to $2.00 per minute. Add roaming charges if you're traveling—Verizon lists rates over $3 per minute before roaming fees apply—and that number climbs higher.
The bigger problem is transparency. Many carriers don't show international call costs upfront, so you won't know the actual price until your bill arrives.
VoIP and pay-as-you-go rates
VoIP services offer UK landline rates starting around $0.03 to $0.05 per minute. With pay-as-you-go pricing, you see the exact rate before every call and pay only for minutes used.
| Method | Typical UK landline rate | Rate shown upfront? |
|---|---|---|
| Mobile carrier | $0.50–$2.00/min | Often no |
| Mobile carrier + roaming | $1.00–$3.00/min | Usually no |
| VoIP pay-as-you-go | $0.03–$0.10/min | Yes |

Cheapest ways to call UK landlines from abroad
Browser-based VoIP services
Browser-based calling lets you dial UK landlines directly from Chrome, Safari, or Firefox—no app download required. You connect over Wi-Fi or mobile data, which means no roaming charges.
Services like CallTuv show the per-minute rate before you dial. You pay only for minutes used, and credits don't expire.
International calling apps
Mobile apps for Android and iOS can also connect to the UK phone network. Look for apps that show rates upfront, work on Wi-Fi, and don't require monthly subscriptions.
The key is finding apps that call actual phone numbers, not just app-to-app. UK landlines can't receive app-only calls.
Prepaid calling cards
Calling cards still exist, but they often include hidden connection fees, maintenance charges, and expiration dates. VoIP services have largely replaced them with more transparent pricing.
Best time to call the UK from abroad

How to avoid roaming charges when calling the UK
Using your regular mobile plan abroad means paying roaming fees on top of international rates. The FCC advises using calling apps over Wi-Fi to reduce these charges, which is why travelers and digital nomads connect to Wi-Fi and use a VoIP service instead.
Hotel Wi-Fi, airport lounges, cafés, and mobile hotspots all work. CallTuv delivers clear audio quality even on hotel or airport networks.
- Turn off cellular data: Prevents accidental roaming charges
- Connect to Wi-Fi: Use hotel, airport, or café networks

FAQs about calling UK landlines from abroad
Is the UK phone code +44 or 0044?
Both work identically. The + symbol is a universal placeholder for your country's exit code, so +44 and 0044 (or 011 44 from the US) all route to the same place.
Is +44 the same as 0 in UK phone numbers?
Yes. The +44 replaces the leading 0 when dialing from abroad. UK residents dial 0 to start domestic calls, but international callers use +44 instead.
Do I dial a 0 when calling the UK from abroad?
No. Drop the leading 0 and replace it with +44 or your exit code plus 44. Including the 0 will cause the call to fail.
Can I call a UK landline from abroad for free?
Generally no. UK landlines require a paid connection to the phone network. VoIP services offer rates as low as $0.03/minute, making calls affordable without being free.
Can I use my own phone number as caller ID when calling UK landlines?
Some VoIP services allow you to display your own number as the caller ID, or block your number for privacy. This is useful for business calls where the recipient expects to recognize who's calling.
Do UK landline and mobile call rates differ when calling from abroad?
Yes. Calling UK mobile numbers typically costs more than calling UK landlines. Check rates for both before dialing—the difference can be significant.
