How to Dial International Number: A Step-by-Step Guide

Knowing how to dial international number correctly saves you dropped calls, wasted minutes, and the frustration of a line that will not connect. Once you learn how to dial international number, the same four-part pattern works for every country on earth.

This guide breaks down the dialing prefix, the + symbol, the country code, and the area code in full, with clear examples you can copy. Read on and your next call abroad will connect on the first try.

Key Takeaways

• Every international call follows one order: prefix + country code + area code + local number.
• The exit code is 011 in the US, 00 in most of Europe and Asia, and 0011 in Australia.
• The + symbol replaces that prefix, making how to dial international number the same from every country.
• You usually drop the leading 0 of a foreign area code, because the country code takes its place.

The Dialing Formula in One Line

The whole trick to how to dial international number is one fixed order. No matter where you are calling from or to, the sequence never changes:

Prefix → Country code → Area code → Local number.

That single line is the international dialing format. The only piece that changes from country to country is the prefix at the front, which is exactly why the + symbol exists. Learn these four parts once and knowing how to dial international number becomes second nature.

Step 1: The Exit Code (or the + Symbol)

The exit code, also called the international access code, tells your carrier that the call is leaving your country. It comes first in how to dial international number, before anything else. This one part changes depending on where you dial from.

Why the + Symbol Wins

On any mobile, press and hold 0 to type +. This one symbol replaces whichever prefix your country uses, so a number saved as + 44 20 7946 0958 dials correctly whether you are in New York, London, or Sydney. Saving contacts with + is the simplest way to make how to dial international number a non-issue.

The plus sign matters most for travelers. If you save a home contact with your local prefix baked in, that number stops working the moment you land in another country.

Store it with + instead, and the phone fills in the right prefix automatically wherever you go — one small habit that makes how to dial international number effortless for the rest of the trip.

Step 2: The Country Code

After the prefix comes the country code, the one-to-three-digit number that routes your call to the right nation. The + symbol always sits directly in front of it, and it is the second piece of how to dial international number.

• +1 — United States and Canada
• +44 — United Kingdom
• +61 — Australia
• +91 — India
• +234 — Nigeria
• +52 — Mexico

Country codes never change, so it is worth learning the ones you call most. Our USA country code guide covers +1 in depth, including the countries that share it, and our full country code list covers every nation in one searchable table.

Watch the length, because codes are not all the same size. Big regions get short codes like +1 or +7, while smaller nations carry three digits such as +234 for Nigeria or +351 for Portugal.

Reading the code carefully is a quiet but vital part of how to dial international number, since a single missed digit routes your call to the wrong country entirely.

Step 3: The Area Code and Local Number

The last part of how to dial international number is the number itself: the area code (if the country uses one) followed by the local subscriber number. This is where one common rule trips people up.

Many countries print numbers with a leading 0, a national trunk prefix used only for domestic calls. When you dial internationally, you drop that 0, because the country code already does its job. A London number written 020 7946 0958 becomes + 44 20 7946 0958, with the 0 removed. The same rule appears in our US number format guide.

Countries With No Area Code

Some numbers, like mobiles in many countries and US toll-free lines, carry no separate area code. You still follow the same order — prefix, country code, then the full number — so how to dial international number stays simple, just without a middle block to worry about.

A Full Example, Dialed From Start to Finish

Say you are in the United States and want to call a London landline printed as 020 7946 0958. Here is how to dial international number step by step:

Read that string left to right and every part has a job: 011 leaves the US, 44 selects the UK, 20 names London, and 7946 0958 rings the line. Once you have walked through how to dial international number this way a single time, the pattern sticks.

Swap in any country code and number, keep the order intact, and the very same steps connect a call to Tokyo, Lagos, or Buenos Aires without a second thought.

How to Get a Virtual Phone Number from CallMama

Once you know how to dial international number, a virtual number makes those calls cheaper and simpler. CallMama gives you a real number that works over the internet from any country, with low flat rates and no roaming, ideal for staying in touch across borders. Here is how to set one up.

Common Mistakes That Break International Calls

• Forgetting the prefix — without 011, 00, or the + symbol, the call never leaves your country.
• Keeping the leading 0 — a foreign trunk 0 must be dropped once the country code is in place.
• Using the wrong country code — double-check it; +1 and +44 reach very different places.
• Adding your own trunk prefix — the 0 you dial at home has no role in an international call.
• Ignoring the clock — the number can be right while the hour is rude, so check the time zone first.

These few rules match the global standards behind every international call prefix, so the same logic holds worldwide once you master how to dial international number.

Most of these slips share one root cause: treating an overseas number like a local one. When you learn how to dial international number as a fixed four-part sequence, you stop guessing and start following a rule that never fails.

If a call will not connect, walk back through the parts in order — prefix, country code, area code, local number — and the missing or extra digit almost always reveals itself. That habit turns how to dial international number from a source of dropped calls into something you barely have to think about at all.

Conclusion

Knowing how to dial international number comes down to one simple order: exit code, country code, area code, then the local number. The leading prefix changes by country — 011, 00, or 0011 — but the + symbol replaces all of them on any mobile phone.

Remember to drop the leading 0 of a foreign area code, and check the time zone before you call. Master the international dialing format once and every call abroad connects.

Dialing correctly is only half the story; the cost is the other half. A virtual number turns pricey international calls into low flat-rate ones you can place from any device, no roaming plan required.

Learn the format once, pair it with the right number, and the whole world is a few taps away. Set yours up today and call across borders with total confidence.
