What is a country code?
A country code is the numeric prefix — like +1, +44, or +91 — dialed at the very start of an international phone number. It tells the global telephone network which country a call belongs to, before the area code and local number ever come into play.
It routes calls between countries
The country code is the first thing the network reads, sending your call to the right nation before any local routing begins.
It follows a global standard
Every code is assigned by the ITU under the E.164 standard — one to three digits long, and identical from any phone on earth.
It comes after your exit code
On a mobile you simply press +; from a landline you dial an exit code such as 00 or 011 first, then the country code.

Anatomy of an International Number
Every international call follows the same four-part sequence defined by the ITU E.164 standard. Here’s exactly how a call to London breaks down.
Exit / IDD Code
Your country's prefix to dial out of the national network — 011 in the US, 00 across Europe, or simply + on any mobile phone.
Country Code
Routes the call to the destination nation. The UK is +44; every country in this directory has its own unique code.
Area Code
Targets a city or region inside that country. Drop any leading 0 — London dials as 020 locally but 20 from abroad.
Local Number
The subscriber line you are actually reaching within that area. Dial it exactly as written.
Three steps to make any international call
Find the Code
Search by country name or dial code. Every entry shows the full +XX prefix, ISO codes, and capital.
Dial the Sequence
Prefix with your country's IDD exit code (usually 00 or + on mobile), then the country code, area code, and local number.

Frequently Asked Questions
An international dialing code — also called a country calling code — is the numeric prefix you dial before a local number to route calls internationally. Defined by the ITU E.164 standard, each country has a unique code, such as +1 for the US/Canada or +44 for the UK.
From a mobile, press + (usually hold 0) followed by the country code and local number. From a landline, dial your country's IDD exit code first (011 from the US/Canada, 00 from Europe), then the country code, area code, and subscriber number.
A country code routes your call to the correct nation — it comes first in any international sequence. An area code is a sub-national prefix routing to a specific city or region within that country. Some small nations use no area codes and route directly from the country code.
An exit code — also called an IDD prefix — tells your local network that the call is leaving the country. You dial it before the country code. It is 011 in the US and Canada, 00 across most of Europe, Asia and Africa, and 0011 in Australia. On any mobile phone you can replace it with a + symbol, which works worldwide.
Many countries use a leading 0 (a national trunk prefix) for domestic calls — for example London numbers start 020. That trunk prefix is only for calls made inside the country. When dialing internationally you replace it with the country code, so 020 becomes +44 20. Keeping the 0 will cause the call to fail.
