How to Call London from Canada: 10 Steps

Calling London from Canada is one of those things that sounds like it should require a trench coat, a rotary phone,
and a secret handshake. In reality, it’s just a predictable set of digitsplus a few “gotchas” (looking at you,
mysterious UK leading zero).

This guide walks you through exactly how to dial London from Canada in 10 steps,
with real examples, money-saving tactics, and troubleshooting tipsso you spend more time chatting and less time
listening to an automated voice politely telling you your call can’t be completed (again).

Before You Dial: The 3 Numbers That Matter

International calls are basically a three-part recipe:
exit code (how you “leave” Canada), country code (where you’re going),
and area/mobile code (where in that country you’re landing).

• Exit code from Canada: usually 011 from landlines, or + on mobile.
• United Kingdom country code: 44.
• London area code: 20 (and you typically drop the leading “0” used inside the UK).

If you remember nothing else, remember this: for London landlines, you’re aiming for something like
011 44 20 XXXX XXXX (from a Canadian landline) or +44 20 XXXX XXXX (from a mobile).

How to Call London from Canada in 10 Steps

1. Step 1: Pick your calling method (cell, landline, or app)

   Decide what you’re using:
   cell phone, landline, or an internet calling app
   (WhatsApp, FaceTime Audio, Zoom/Teams calling, etc.).
   This matters because mobile phones can often use the + shortcut, while landlines typically use 011.

2. Step 2: Check your plan and rates before you “accidentally” fund a telecom yacht

   International calling rates can range from “totally fine” to “I could’ve flown there for this.”
   Log into your carrier account and confirm:

   • whether international calling is enabled
   • your per-minute rate to the UK (landline vs mobile can differ)
   • any add-ons that make UK calling cheaper

   If you’re calling frequently, an international add-on or a VoIP solution can be dramatically cheaper than pay-per-minute.

3. Step 3: Get the number in the right format

   The best practice is to store UK numbers in international format (often called E.164 format),
   which starts with +44. It prevents future confusionespecially if you travel.

   If the London number is written like 020 1234 5678 (common UK style), that first 0 is a domestic “trunk” prefix.
   When calling from Canada, you typically drop that 0.

4. Step 4: Identify whether it’s a London landline or a UK mobile

   This changes what you dial after 44:

   • London landline: usually written as 020 xxxx xxxx in the UK (area code 20 + 8-digit local number).
   • UK mobile: often starts with 07… in the UK (you drop the 0 when calling internationally).

5. Step 5: Start with Canada’s international access (011) or use + on mobile

   From a landline in Canada: dial 011 to start an international call.

   From a mobile phone: you can usually press and hold 0 to get the + sign.
   The + essentially acts like the correct international exit code automatically.

6. Step 6: Dial the United Kingdom country code (44)

   After 011 or +, enter 44. You’re now officially “in” the UKdigitally speaking.

7. Step 7: For London landlines, dial the London area code (20) and drop the leading 0

   If the number is shown as 020 in the UK, you dial 20 from Canada (not 020).
   Example: UK domestic: 020 1234 5678 → International: +44 20 1234 5678.

8. Step 8: Dial the local number

   For London landlines, the local part is typically 8 digits.
   Enter it exactly as written (just without the UK trunk “0”).

   For UK mobiles written as 07xxx xxxxxx, drop the leading 0 and dial the remaining digits after 44.

9. Step 9: Press calland if it fails, troubleshoot fast

   If the call doesn’t connect, don’t keep redialing like it’s a game of chance. Common fixes:

   • You kept the UK leading 0: try again without it (020 → 20; 07… → 7…).
   • International calling blocked: some plans require enabling international calling.
   • Wrong type of number: premium-rate or service numbers may not work from abroad.
   • PBX/office phones: you may need to dial a prefix like 9 before 011.

10. Step 10: Make it cheaper (and clearer) for the next call

    Once your call works, lock in the win:

    • Save the contact as +44 … so you don’t redo the math later.
    • Use Wi-Fi Calling if your carrier supports it (great for weak signal areas).
    • Try VoIP/apps for longer chats (often cheaper; sometimes free on Wi-Fi).
    • Schedule smart so you’re not calling London at 3 a.m. unless you enjoy being hated.

Examples: Exactly What to Dial (Copy/Paste Friendly)

Note: The numbers below are examples for formattingnot real contacts.

Example A: Calling a London landline from a Canadian landline

UK number shown locally: 020 1234 5678
Dial from Canada: 011 44 20 1234 5678

Example B: Calling a London landline from a Canadian mobile

Dial: +44 20 1234 5678
(Tip: press and hold 0 to get the + on most phones.)

Example C: Calling a UK mobile from Canada

UK mobile shown locally: 07123 456789
Dial from Canada: 011 44 7123 456789 (or +44 7123 456789)

When to Call: Time Zone Tips That Save Relationships

London is several hours ahead of Canada. The exact difference depends on:
your Canadian time zone and daylight saving time on both sides.

• From Eastern Canada (ET): London is often about 5 hours ahead in winter.
• From Pacific Canada (PT): London is often about 8 hours ahead in winter.

A practical rule: call London in your late morning or early afternoon.
That usually lands in London’s afternoon/eveningaka “awake and not furious.”

Cost and Call Quality: What Changes the Bill (and the Audio)

What affects the cost

• Your carrier rate: per-minute pricing varies wildly by plan and carrier.
• Landline vs mobile in the UK: some plans price them differently.
• How you place the call: cellular, Wi-Fi Calling, VoIP app, or calling card.

What affects call quality

• Signal strength: weak reception can make international calls sound like they’re underwater.
• Wi-Fi quality: Wi-Fi Calling and VoIP apps depend on stable internet (and not the café router from 2009).
• Network congestion: evenings and weekends can be busier.

Troubleshooting: The Top 7 Reasons Your Call Won’t Connect

1. You dialed 020 instead of 20 after the country code.
2. International calling isn’t enabled on your plan.
3. You used 00 instead of 011 (00 is common in Europe; Canada typically uses 011 for direct dialing).
4. You forgot the country code and dialed a number that looks local (to your phone’s confusion).
5. The number is a premium/service number that may not accept international calls.
6. You’re dialing from a work phone system that requires an outside-line prefix (like 9).
7. Your phone is forcing the wrong route (try saving the number as +44 in contacts and calling from there).

Real-World Experiences and Lessons Learned (Extra 500+ Words)

People rarely struggle with the idea of international callingthey struggle with the tiny details that feel
too small to matter… right up until they matter a lot. Here are common “been there” experiences (and what to do so
you can skip the frustration and get straight to the conversation).

The “Why Is There a Zero?” Moment

One of the most common first-time mistakes is dialing the UK number exactly as it appears on a British website:
020 1234 5678. From inside the UK, that leading 0 helps route calls domestically.
From Canada, keeping it often leads to a failed call or a recording. The fix is simple: treat the 0 like a
“local-only” helper. When you go international, it stays behindkind of like a friend who says they’re “down to travel”
but mysteriously disappears when it’s time to leave for the airport.

The “It Worked Yesterday” Mystery

Another very real experience: your call worked last week, but now it’s failingsame number, same phone, same you.
That can happen if your carrier toggles international calling blocks (for security), your plan changes, or you hit a
spending limit. Some carriers automatically block unusual calling patterns to prevent fraud. The best move is not to
keep redialing; instead, confirm that international calling is enabled and check whether your plan requires an add-on.
If you’re calling London often (family, work, long-distance relationship, or you just really love London rain),
a dedicated international calling option can reduce both cost and weird interruptions.

The “My Call Sounds Like a Robot Whale” Problem

Audio quality issues are incredibly common, especially from basements, elevators, older buildings, or anywhere your
phone shows one bar and a brave attitude. The practical workaround many people swear by is using Wi-Fi Calling
when available. If your carrier supports it, Wi-Fi Calling can turn a choppy cellular connection into a clearer call
over home internet. If Wi-Fi Calling isn’t an option, a VoIP app can also work wellbut only if your Wi-Fi is stable.
(If your router reboots whenever someone microwaves popcorn, maybe don’t rely on it for a heartfelt international call.)

The “Why Did This Cost So Much?” Surprise

Plenty of people learn international calling rates the hard way: they assume a quick call is “basically nothing,”
then discover the per-minute cost is not nothingespecially for longer conversations. The best experience-based tip is
to decide in advance: Is this a short coordination call, or a long catch-up? For short calls, your carrier
might be fine. For long calls, many people switch to a cheaper route: an international add-on, a calling plan, or internet-based calling.
Even if you stay on cellular, you can save money by calling London during off-peak hours (depending on your plan) and keeping calls focused.
Not romantic, surebut neither is a surprise bill.

The “I’m Traveling and Everything Changed” Reality Check

A final common experience: you set everything up in Canada, then travel and suddenly dialing is confusing again.
That’s why storing contacts in +44 format is a lifesaver. The + format is designed to be location-agnostic:
it works whether you’re in Canada, the U.S., or sitting in an airport desperately hunting for a power outlet.
People who store numbers in international format report fewer “why won’t this work?” momentsbecause the phone can route it properly
without you remembering exit codes for every country on Earth.

Bottom line: the digits are easy. The experience gets easy when you (1) drop the UK trunk zero, (2) use +44 formatting,
(3) verify your plan, and (4) choose the right calling method for the kind of conversation you’re actually having.
Do that, and calling London from Canada becomes routinelike making tea, except with fewer kettles and more emojis.

Conclusion

Calling London from Canada boils down to a clean formula: start with 011 (or + on mobile),
add 44, then dial the London code 20 (without the UK’s leading 0), followed by the local number.
Once you do it onceand save the contact as +44…it becomes a two-second task instead of a mini puzzle.

Whether you’re calling for family, work, travel plans, or to argue about what “chips” means, you now have a reliable,
repeatable method (and a few budget-friendly options) to get through without drama.
