Country Code List: How to Dial From the US

To call any other country from the United States, dial 011, then the country code, then the national number with any leading trunk 0 dropped — for example 011 44 20 7946 0958 reaches a London landline. On a mobile phone, the + key substitutes for 011. That single pattern covers every destination on this page.

The 011 prefix is the North American exit code — the digits that tell your carrier the call is leaving the North American Numbering Plan. What follows it is the country code assigned by the ITU, one to three digits, and then the number as dialed inside that country minus its domestic trunk prefix. Below is the full working list, organized the way the ITU actually assigns codes: by world zone.

Country codes by world zone

The first digit of every country code is its ITU zone. Once you know the zones, an unfamiliar code stops being random — a code starting with 3 or 4 is Europe, 5 is Latin America, 6 is Southeast Asia and Oceania. All of these are dialed from the US as 011 + code + national number.

Zone 1 — North America and the Caribbean

Country	Code
United States, Canada, and most of the Caribbean	+1

Zone 1 is one shared code covering roughly two dozen countries and territories — see which countries share the +1 country code for the full picture and why a +1 number is not automatically a US number.

Zone 2 — Africa

Country	Code
Egypt	+20
South Africa	+27
Morocco	+212
Ghana	+233
Nigeria	+234
Kenya	+254

Zones 3 and 4 — Europe

Country	Code
Greece	+30
Netherlands	+31
Belgium	+32
France	+33
Spain	+34
Hungary	+36
Italy	+39
Romania	+40
Switzerland	+41
Austria	+43
United Kingdom	+44
Denmark	+45
Sweden	+46
Norway	+47
Poland	+48
Germany	+49
Portugal	+351
Ireland	+353
Ukraine	+380
Czech Republic	+420

Most European countries use a trunk 0 in domestic dialing that is dropped internationally — the +44 UK guide and the +49 Germany guide show exactly which digits survive the conversion.

Zone 5 — Mexico, Central and South America

Country	Code
Peru	+51
Mexico	+52
Argentina	+54
Brazil	+55
Chile	+56
Colombia	+57
Costa Rica	+506

Mexico deserves a note: since its August 2019 numbering reform, every Mexican number is a uniform 10 digits and the old mobile “1” and 044/045 prefixes were eliminated. Old instructions still circulate — the +52 Mexico country code guide covers the current rules.

Zone 6 — Southeast Asia and Oceania

Country	Code
Malaysia	+60
Australia	+61
Indonesia	+62
Philippines	+63
New Zealand	+64
Singapore	+65
Thailand	+66

Zone 7 — Russia and Kazakhstan

Country	Code
Russia, Kazakhstan	+7

Zone 7 is, besides +1, the only code the ITU assigns to multiple sovereign countries — a legacy of the Soviet numbering plan.

Zone 8 — East and South Asia

Country	Code
Japan	+81
South Korea	+82
Vietnam	+84
China	+86
Hong Kong	+852
Bangladesh	+880
Taiwan	+886

Zone 9 — Middle East, South and Central Asia

Country	Code
Turkey	+90
India	+91
Pakistan	+92
Sri Lanka	+94
Jordan	+962
Saudi Arabia	+966
United Arab Emirates	+971
Israel	+972

How to read a full international number

A complete international number has three parts: the + (or your exit code), the country code, and the national significant number. Written in the international standard it looks like +913322445566 — no spaces, no dashes, maximum 15 digits total. That standard is E.164, and our E.164 format guide is the full reference, including why SIP trunks and dialers require it.

The conversion trap is the trunk prefix. A Londoner writes their number as 020 7946 0958; internationally it is +44 20 7946 0958 — the leading 0 is a domestic dialing instruction, not part of the number. The UK, Germany, India, and Australia all drop a trunk 0 this way. NANP numbers never do, because +1 countries have no trunk 0 to drop.

Zones worth knowing before you dial

Three structural facts prevent most dialing mistakes:

• +1 is a zone, not a country. The US, Canada, and most Caribbean nations share it, distinguished only by area code. A +1-876 call terminates in Jamaica, not Texas — a detail with real billing consequences, covered in the USA country code guide.
• Code length signals numbering history, not importance. The one-digit codes (+1, +7) went to the largest mid-century networks; later entrants got two or three digits, balanced so the total stays within 15 digits.
• National number length varies by country. India is a fixed 10 digits after +91; Germany is variable-length after +49. Never pad or truncate a foreign number to make it “look right.”

What international calls cost

Per-minute pricing to any given country varies enormously by route, by destination type (landline, mobile, premium), and by the quality of the terminating carrier — which is why published one-size rate tables age badly and cheap-looking routes often hide dead air and failed calls. We do not publish an A-Z rate deck. If you have international destinations, ask: we quote routes we can stand behind.

Deep dives by country

Each major corridor gets its own guide, with the exact digit-by-digit conversion for that country:

• USA country code +1 — the NANP zone, and which countries share it
• UK country code +44 — dropping the trunk 0, London and mobile formats
• Germany country code +49 — variable number lengths explained
• India country code +91 — the 10-digit rule and trunk-0 conversion
• Mexico country code +52 — the 2019 reform and uniform 10-digit dialing
• How to call Mexico from the US — step-by-step for the busiest US corridor
• How to call Australia from the US — +61 formats and the time-zone window

Frequently asked questions

Is 011 the same as the + sign when dialing internationally?

Functionally yes. 011 is the North American exit code — the literal digits US and Canadian networks use to route a call out of the +1 numbering plan. The + is the universal placeholder for “your country’s exit code,” whatever it is (00 in most of Europe). A number saved as +44… dials correctly from any country; a number saved as 011 44… only works from NANP countries.

How do I dial an international number from a US cell phone?

Hold the 0 key until a + appears, then dial the country code and national number — the phone translates + into 011 automatically. Dialing the literal 011 also works. Storing contacts in full international format with the + (the E.164 standard) is the better habit: those entries dial correctly from the US, while roaming abroad, and from any VoIP app.

Why are some country codes one digit and others three?

The ITU assigned short codes to the biggest mid-century telephone networks — +1 for North America, +7 for the Soviet Union — and progressively longer codes as more countries joined, so that country code plus national number stays within the 15-digit E.164 maximum. A three-digit code like +254 (Kenya) says nothing about call quality or reachability; it only reflects when and where the code was carved out of its numbering zone.

Which countries share a single country code?

+1 and +7 are the only codes the ITU assigns to multiple sovereign countries: +1 covers the United States, Canada, and most Caribbean nations under the North American Numbering Plan, and +7 covers Russia and Kazakhstan. Several dependencies also ride a parent country’s code — the Crown Dependencies (Jersey, Guernsey, the Isle of Man) carry +44 without being part of the UK; see the +44 guide. Within +1, the area code determines the actual country — which matters for billing, since a +1 Caribbean call is an international call even though it dials like a domestic one.
